Idea Man: A Memoir by the Cofounder of Microsoft – Allen

2011, Penguin, 358 pages

Book Blurb

“The entire conversation took five minutes. When it was over, Bill and I looked at each other. It was one thing to talk about writing a language for a microprocessor and another to get the job done…. If we’d been older or known better, Bill and I might have been put off by the task in front of us. But we were young and green enough to believe that we just might pull it off.”

Paul Allen, best known as the cofounder of Microsoft, has left his mark on numerous fields, from aviation and science to rock’n’roll, professional sports, and philanthropy. His passions and curiosity have transformed the way we live. In 2007 and again in 2008, Time named him one of the hundred most influential people in the world.

It all started on a snowy day in December 1974, when he was twenty-one years old. After buying the new issue of Popular Electronics in Harvard Square, Allen ran to show it to his best friend from Seattle, Bill Gates, then a Harvard undergrad. The magazine’s cover story featured the Altair 8800, the first true personal computer; Allen know that he and Gates had the skills to code a programming language for it. When Gates agreed to collaborate on BASIC for the Altair, one of the most influential partnerships of the digital era was up and running.

While much has been written about Microsoft’s early years, Allen has never before told the story from his point of view. Nor has he previously talked about the details of his complex relationship with Gates or his behind-closed-doors perspective on how a struggling start-up became the most powerful technology company in the world. Idea Man is the candid and long-awaited memoir of an intensely private person, a tale of triumphant highs and terrifying lows.

After becoming seriously ill with Hodgkin’s lymphoma in 1982, Allen began scaling back his involvement with Microsoft. He recovered and started using his fortune–and his ideas–for a life of adventure and discovery, from the first privately funded spacecraft (SpaceShipOne) to a landmark breakthrough in neuroscience (the Allen Brain Atlas). His eclectic ventures all begin with the same simple question: What should exist? As Allen has written:

To me, that the most exciting question imaginable…. From technology to science to music to art, I’m inspired by those who’ve blurred the boundaries, who’ve looked at the possibilities, and said, “What if…?” In my own work, I’ve tried to anticipate what’s coming over the horizon, to hasten its arrival, and to apply it to people’s lives in a meaningful way…. The varied possibilities of the universe have dazzled me since I was a child, and they continue to drive my work, my investments and my philanthropy.

Idea Man is an astonishing true story of ideas made real.

Paul Allen is the billionaire technologist and philanthropist who cofounded Microsoft with Bill Gates. He is the chairman of Vulcan Inc. and founder of the Allen Institute for Brain Science. He also owns the Seattle Seahawks and the Portland Trail Blazers, and is co-owner of the Seattle Sounders pro soccer team. He lives on Mercer Island, Washington.

Idea Man

A few months ago, me and JS were chatting at work about what we can learn from good role models. I mentioned Warren Buffett and Elon Musk. From Buffett, I learned of optimism. For example, when asked how I’m doing, like Buffett, I answer, “Never better.” It gets the conversation flowing in the right direction. From Musk, I learned how important it is to be a showman when promoting your ideas. Great ideas need great presentation. There was a Tesla AGM a few years back. The issue with electric cars was that they take too long to charge. Musk came up with the idea of Tesla service stations where they would swap out your battery. On the big stage, he had a mock-up of a service station. An actor drove up a Tesla for a battery swap. On the video screen, he had another actor pull up to the fastest gas pump in LA to fill up an Audi. He set it up as a competition. While the Audi was being filled up, the first battery swap was complete. Then the second Tesla rolled up…then the third…the crowd went wild. That’s showmanship!

JS then mentioned his influences. One of them was Paul Allen, who had recently passed away (October 15, 2018, aged 65). JS suggested that we read Allen’s book Idea Man and compare notes. He had been impressed by Allen’s role as one of the founding fathers of the digital revolution and his subsequent ventures into the arts and sciences. I picked up a copy at the library and started reading. By the way, the library is the best resource in the world!

What can I say about Paul Allen’s character? Much of his success can be attributed to his perseverance. He spent three years talking to Bill Gates about the personal computer concept before convincing him to create a BASIC code for the Altair 8080 (in the 70s, the personal computer wasn’t such a sure thing: the standard model was for large institutions to rent out computing power to clients). Another of Allen’s strengths was that he was a good communicator. Till his last days with Microsoft, he would wander the halls and chat with programmers to work out solutions with them.  Allen spends much of the book talking about his fascination with ideas, and this is perhaps his strongest characteristic. It is his fascination with ideas that motivated him to revolutionize how we use computers. It is his fascination with ideas that motivated him to launch the SpaceShipOne venture, one of the first private attempts at spaceflight. It is his fascination with ideas that motivated him to team up with Carl Sagan to fund SETI. It is his fascination with ideas that motivated him to launch the Allen Institute for Brain Science. Allen reminds me of Goethe’s Faust, who defines himself by continually striving. Allen is like Faust, who, up to his dying day, can be found working on monumental projects such as reclaiming land by building a series of dikes to push back the sea.

Allen had his strengths, but he also had his weaknesses. He is not as dominant a personality as his peers and colleagues, such as Bill Gates and Clyde Drexler. As a result, one feels that sometimes he could have done better in negotiations. He comes across as learned, but he does not come across as someone fascinating. Innovators such as Musk, Jobs, or Gates come across as fascinating. Allen seems more down to earth. A good way to put it is that he surrounds himself with people more fascinating than himself. I’d have a beer with Jobs or Musk. But I’m not so sure if I’d like to have a beer with Allen.

Now the book is 358 pages long, and you can say quite a bit in 358 pages. There is one peculiar and glaring omission: nothing about his love life or relationships with women. He’s close with his mom, and quite close with his sister (who also takes leadership roles in his philanthropy projects), but there’s nothing about romantic relationships. From reading the book you’d think that all his life he’s either coding or playing guitar or pursuing space travel. That’s hard to believe. Remember that even Descartes, who locked himself in an attic to come up with the irreducible human axiom upon which to base all philosophy (which turned out to be “I think, therefore I am”) managed to get his maid pregnant. Perhaps his credo could have been modified to read, “I reproduce, therefore I am”? It would have been interesting to have read about Allen’s romantic relationships, and to learn about how they affected his thinking.

The takeaway from this book? Allen teaches us to pursue our ideas. He teaches us how powerful childhood is: it is during his childhood that he developed a fascination for programming, AI, space travel, and the hidden workings of the mind. He talks about mortality in the book (two brushes with cancer), and the book reminds me of my own mortality. His breakthrough year when he started programming BASIC to run the Altair was 1974, the same year I was born. Now Allen is gone. The time to want it all and to do it all is right now. This is something we can all take away from this book.

Until next time, I’m Edwin Wong, and I’m doing Melpomene’s work.

Risk Theatre Modern Tragedy Competition – December 2018 Update

Stats, stats, stats!

Thank you assiduous playwrights for all your entries! Here are the vital statistics since the competition began seven months ago on June 1, 2018. Fifty-one plays have come in from three continents (North American, Europe, and Oceania) and five countries (USA, Canada, UK, Australia, and Ireland). Here’s the country breakdown:

USA 43 entrants

Canada 4 entrants

Australia 1 entrant

England 2 entrants

Ireland 1 entrant

Of the American entries, 29 are from the east and 14 are from the west. There is a concentration of dramatists in New York (nine entrants) and Chicago (four entrants) and LA (three entrants). Write away New York, Chicago, and LA!

The breakdown between male and female entrants stands at 37 men and 15 women. While the balance may seem to tilt towards male writers, in a historical context, the numbers are quite progressive: prior to the twentieth century, I only know of one tragedy written by a woman. That play is The Tragedy of Mariam, the Fair Queen of Jewry, written by Elizabeth Cary in 1613. The times, they are a changing!

The website is averaging 16 hits a day this December. Most hits in a day was 196 back in June 2018 when the contest launched. That month also saw 2000+ hits. December 2018 is on pace for 500 views. So far, so good!

The inaugural competition will conclude on March 29, 2019. Three months left. My book The Risk Theatre Model of Tragedy: Gambling, Drama, and the Unexpected is due out February 2019. This coincides nicely with the March date. Complimentary copies will be going out to all the hardworking playwrights who have sent in their scripts. Keep up the good work and thanks for contributing to the success of this one of a kind competition. The book isn’t necessary for the competition: the judges will be scoring plays based on the parameters found in the ‘Guidelines’ section of the website.

Until next time, I’m Edwin Wong, and I’m doing Melpomene’s work.

Coherent Audio – Retro 15 Neo Be Speaker Review

This is a review of the “Retro 15 Neo Be” speaker. It’s a drop-dead gorgeous horn-loaded and hand-made speaker by Frank Fazzalari, founder of Coherent Audio, a small Canadian speaker manufacturer operating out of Stoney Creek, Ontario. The speaker measures 22″ long x 13″ deep x 34″ high. They sit on small stands which raise them 7″ off the ground. This places the tweeter at approximately ear height for seated listeners. On the rear of the cabinet there are two ports. Rear wave resonances are tamed by lattice slats inside the cabinet rather than the more commonly seen polyfill insulation. The front baffle sounds solid when you knock on it. The sides sound less solid. And the top sounds hollow. I believe Frank has tuned the cabinet by using panels of different thicknesses. Like Audio Note speakers, these cabinets are designed to resonate. This philosophy of cabinet design contrasts with the current craze to make cabinets as inert as possible by using multiple layers of composite materials or, in some cases, aluminum enclosures.

The speakers probably weigh close to eighty pounds–one person can move them, but with difficulty. The level of woodworking, from how the terminal posts are inset into the cabinet to how the model name is stamped into the cabinet, is superb. I think of these speakers as a piece of fine furniture that happens to convert electrical into sound energy. Size and finish wise, they bear a physical resemblance to the DeVore Orangutan O/96, another lovely and well-regarded speaker.

This is the demo pair from Coherent Audio’s booth at the 2017 Toronto Audio Visual Entertainment Show, otherwise known as “TAVES.” There they were powered by a Triode Amps 2A3 setup, a captivating combination of a lower power tube amplifier with a high efficiency speaker. Since there were no local dealers, I travelled to Toronto to have a listen. Also on the listening list at TAVES were the JBL Synthesis K2 ($80,000), the GoldenEar Triton Reference ($11,000), and various speakers by PMC. PMC champions transmission line cabinets where the rear wave of the speaker goes through a tuned labyrinth. They claim that this results in deeper and more integrated bass than either sealed or ported designs. I find this approach fascinating and wanted to have a listen. The GoldenEar Triton References were appealing because their low-end has been compared to that of the legendary Mirage M3s, a speaker I lived with and enjoyed for many years. They could produce subterranean bass that energizes the room. To be able to charge up a room is great fun. And the JBL I wanted to hear because JBL is a legend and the K2 was there attempt at a state-of-the-art horn design. Unlike the speakers by Coherent, GoldenEar, and PMC, I was not planning on buying the K2s. At $80,000 it was listening only! In the end, I purchased the Coherent Retro 15 Neo Be demo pair from Frank for $11,165 (CAD), shipping included. They were 3 months old, so they were pretty much new. At the time of writing this review, I’ve enjoyed the speaker for a year. This last year I moved, so I’ve also experienced how they perform in different settings.

At the heart of the Coherent Audio Retro 15 is a modified Radian 5215 15″ Neo Coaxial Speaker. These bad boys are designed for commercial applications, boast a 700 watt AES power handling capacity (!), and retail for $1200 (CAD) each. A 3″ horn loaded driver handling the frequencies above 800 Hz is built into the dustcap of the 15″ treated paper woofer, hence the “coaxial” designation. The advantage of coaxial designs is that the low and high frequency drivers are time-aligned. Conventional speakers that have separate woofers and tweeters mounted on a panel are not time-aligned: the different frequencies arrive at the ear fractions of a second apart, smearing the presentation. Heroic crossover design can ameliorate this, but with a coaxial speaker, time alignment happens automatically. The Radian 5215s combine two great technologies. They are time-aligned. And they are, above 800 Hz, horn loaded, which makes them super efficient. With one or two watts of power, they will fill most rooms with concert hall levels of sound. On a side note, Radian is the last manufacturer who still builds and assembles all their drivers in the USA.

What modifications has Frank done to the Radian 5215? He took off the dustcap so you can see the high-frequency horn in the centre of the speaker (no grilles come with the speaker). And he discarded the Radian designed crossover with an autoformer of his own devising. You see, the 5200 series Radian drivers were designed for punishing commercial use. The crossover was designed to protect the speakers, not for audiophile sound. Sound wise, it’s like a horse-blanket. Frank’s genius was to recognize that, if he could come up with an audiophile crossover, the Radian 5215 could be the centrepiece of a world-class home loudspeaker. Traditional crossovers use resistors to match different sensitivities of low- mid, and high-frequency drivers. Autoformers match drivers of different sensitivities by multiplying impedances. Autoformers are much more expensive than resistors. They are, however, much more efficient than resistors, which dissipate the power produced by the amplifier as heat. With autoformers, the amp never has to produce this extra power since the driver appears to the amp as a higher impedance device. The “first watt” crowd will love the autoformer concept: musical purity favours simpler, lower power designs. Klipsch is another manufacturer that combines high-efficiency horns with autoformers, at least in their “Heritage” line.

Horn loudspeakers are the holy grail to me. Horns are efficient. Two or three watts of power is sufficient. No need for half-kilowatt monster amps. You have your choice of any amplifier. Single-ended triode?–check. Output transformerless OTLs?–check. Class A tube or transistor?–check. Huge Krells?–you could use these too. The horn colouration, if anything is an advantage. Commercial speakers, because efficiency is important, are invariably horn loaded. As a result, we naturally associate the sound of horns with live music. Though horns can play loud, they sound extremely pleasing at low volumes. This is true of the Coherent Retro 15s as well as the Klipsch LaScala, another horn I lived with happily for many years. They are a great late night speaker. Horns are quite different than Magnepan panels in this regard. I have owned the MG-II and, more recently, the 3.7i. I love them, but you always are reaching for the volume to turn them higher, and they just soak up the power. Not so with horns. Late night listening sessions are possible with horns. Horns take you closer to the music, as they project more direct sound towards the listener.

While both the Coherent Retro 15s and the Klipsch La Scala use horns, the sound from the Retro 15s is more refined. The La Scalas, on the other hand, tend to grab you more viscerally. Another difference between the two is that the bass driver on the La Scala is a folded horn (a type of compact horn). The bass (and low midrange) handled by the 15″ woofer on the Retro 15s is not horn loaded. As a result, the cabinet size of the Retro 15s is about half the size of the La Scala, which is massive. Both speakers seem to put out a ton of bass. But it’s different bass than the bass from the latest ported speaker designs with multiple low-end drivers such as the Mirage M3 or the GoldenEar Triton References. Those speakers can convulse rooms. The bass from the Retro 15s and the La Scalas is more airy. And since many owners of horn speakers will be using low powered tube amps based on 300B or 2A3 tubes, the bass will have the bloomy tube sound. I’ve had tubes in the past, having built single ended 300B and OTL kits (I build speakers too, which is great fun). But right now, the Coherent Retro 15s are being powered by a Devialet 120 amplifier. It’s an all-in-one design, perfect for condo living: built into one box the size of a bathroom scale is a class A/D amp, a digital-analog converter (DAC), a world-class digital preamp, and a wireless function where you stream music from your computer. No more unsightly box and wire clutter from preamps, amps, transports, and D/A converters. Yay!

Frank expressed surprise when I told him I was going to be using the Devialet with his speaker. He’s built and tuned his speaker to work with tubes. At the show, he demoed the speaker with a 2A3 tube amp. What I love about the Devialet, however, is that it is dead quiet. It is dead quiet, dead accurate, and like horn speakers, it is–being a class A/D amp–efficient. At its hottest the chassis gets up to 45 Celsius. I’ve had tube amps I could fry eggs on. You know, the ones that input 100 watts of power and deliver 2 watts to the speakers. Who needs such inefficiency anymore? I love the Devialet’s analytic and revealing sound. Tubes are fun, but their euphonic characters sometimes add a pleasant bloom to the sound that isn’t there. This bloom masks subtle sonic cues and emphasizes others. Devialets are all about control and efficiency. And yes, you can use them with horns. My Devialet 120 started off as a Devialet 110 five years ago (purchased in 2013 sight unseen). It became a 120 from a free firmware upgrade. We’ll see more and more audio manufacturers take this route in the future. This is as good as Tesla owners who wake up one morning to find they have the new ‘ludicrous’ mode update.

How to the Coherent Retro 15s compare to other horns? Just as they were more refined than the La Scalas (a speaker I’d very happily purchase again), the JBL Synthesis K2s were that much more “airy” in the top end than the Retro 15s. But whereas the Synthesis K2s are a three-way design, the Retro 15s are a time-coherent two-way design. As I get older, I favour simplicity. Two-way rules! Then there are the Tannoy Ardens, another 15″ dual concentric speaker. The Retro 15s, however, blow this legendary speaker out of the water. I auditioned a used pair (with new surrounds in great condition) driven by McIntosh electronics. Like the Retro 15s, they had a big, big, lifelike sound. Perhaps even bigger than the Retro 15s, which have a laser focus to their presentation. But the bass from the Ardens was absolutely out of control. Bloated, big, and flabby. Some may like their gigantic presentation. But, to me, they’re out of control. I’ve also heard the Avantgarde Duos, but it’s been too long to draw comparisons. I do remember that I loved the sound of these beautiful art-pieces and that the powered DSP bass was module was a great idea. They must be going for close to $25,000 (CAD) these days, so they’re out of my price range. At least right now. Maybe one day down the line though. The Avantgarde Solo was in my price range, but they sounded congested.

Here’s one feature of horns that I find very interesting. I used to live in a New York style loft condo: the upstairs is open to the downstairs. One thing that horns do that no other speaker does is that they sound very lifelike from the next room. The speakers were downstairs, and I had a home gym upstairs. When working out, when the horns were playing, it would sound like a real band was playing downstairs. When I had box speakers, it would never sound that real. And the Magnepans sounded downright wrong. It must have something to do with the radiation pattern of the sound?

Now another interesting thing about all these high-efficiency horn speakers (the Retro 15s, La Scalas, Ardens, and K2s) is that, while they seem to pump prodigious bass out of huge boxes, they don’t actually go that deep. The lot of these speakers go down to the low 40s before dropping off. Considering that conventional ported box speakers with 8 or 12 inch drivers can routinely get down to 35 Hz or lower, this doesn’t seem so impressive. Of course, conventional box speakers are much less sensitive and need to be paired with big amps to achieve this. So low bass must be one of the tradeoffs of a horn design. Here’s how the Retro 15s measured from my listening chair (roughly 12′ from the speakers). Measurements taken with Galaxy Audio Checkmate CM-140 SPL meter:

  • 20Hz 59dB (-17dB)
  • 25Hz 59dB (-17dB)
  • 31.5Hz 64dB (-12dB)
  • 40Hz 66dB (-10dB)
  • 50Hz 68dB (-8dB)
  • 63Hz 66dB (-10dB)
  • 80Hz 76dB (0dB)
  • 100Hz 75dB (-1dB)
  • 125Hz 79dB (+3dB)
  • 160Hz 77dB (+1dB)
  • 200Hz 78dB (+2dB)
  • 250Hz 80dB (+2dB)

The Retro 15s measured similarly in my previous condo:

  • 20Hz 60dB (-24dB)
  • 25Hz 61dB (-23dB)
  • 31.5Hz 69dB (-15dB)
  • 40Hz 73dB (-11dB)
  • 50Hz 81dB (-3dB)
  • 63Hz 87dB (+3dB)
  • 80Hz 84dB (0dB)
  • 100 81dB (-3dB)
  • 125 79dB (-4dB)
  • 160 86dB (+2dB)
  • 200 84dB (0dB)
  • 250 84dB (0dB)

They’re fairly flat from 50Hz and up. The 50Hz (-8dB) and 63Hz (-10dB) dips at my current place have more to do with the room than the speaker. They drop off fairly sharply in the 40s and have useable bass down to the low 30s. One thing that’s been illuminating from measuring speakers: a “big” sound isn’t the same as deep bass. A lot of box speakers (such as the Mirage M3s and the Golden Ear Triton Reference) go lower, but the horns sound much bigger. Instruments and voices sound more solid, like they occupy a real space. Box speakers have a leaner, smoother presentation. Horns are raw and elemental. One of my friends, a jazz singer, commented that these were the first speakers she could make out subtle changes in pitch and timbre in her favourite vocal recordings.

To fill in the bottom octave, I went out searching for a subwoofer. Like many of you, I’ve had subs in the past. There was a Yamaha, a B&W, and Hsu. The Hsu ULS-15, a sealed 15″, was actually quite nice. And a good deal. I’ve never been able to perfectly mate the sub to the mains, though. The ULS-15 (with wireless option!) was probably the best of the bunch (the B&W was 12″, too small), but they were matched with the Magnepan 3.7i, a brilliant and exceedingly frustrating speaker. After much research, I ordered a Rythmik FV15HP. It’s a 15″ aluminum cone self-powered dual-ported sub. It is big and it plays at -2dB at 17Hz or -6dB at 12Hz. That’s pretty impressive. I use it with one port plugged. After months of hair-pulling tuning, fidgeting with knobs and controls, and moving things around, here are the frequency measurements with the sub at the listening chair:

  • 20Hz 77dB (+1dB)
  • 25Hz 70dB (-6dB)
  • 31.5Hz 71dB (-5dB)
  • 40Hz 80dB (+4dB)
  • 50Hz 77dB (+1dB)
  • 63Hz 75dB (-1dB)
  • 80Hz 76dB (0dB)
  • 100Hz 73dB (-3dB)
  • 125Hz 75dB (-1dB)
  • 160Hz 81dB (+5dB)
  • 200Hz 77dB (+1dB)
  • 250Hz 82dB (+6dB)

Not bad! +/- 6dB across the board! Purists will inevitably poo-poo adding a sub to such a brilliant time-coherent speaker, but purists be damned! The big sub is big fun. And, every once in a while, when a recording has deep bass (Bach organ music, Andy Stott, Portishead), one is rewarded. The sub also does a good job of bringing out bass guitar lines in rock music, say Springsteen. On most music, the effect of the sub is quite subtle, certainly more subtle than the measurements suggest. Unless I were doing A/B comparisons or listening to electronic music with room shaking bass, I probably couldn’t tell if the sub were on or off. The sub is positioned in a corner behind the right speaker. The left and right speakers are placed about 4′ from back wall (measured from front baffle), so that’s just enough room to fit the sub there. The right speaker almost conceals the sub. Almost. Did I say that the sub is big? And for those of you wondering: “Why not a sealed sub?” the answer is that at my old loft-style place the sub had to energize a 15,000 cubic foot space (30’x20’x25′). Although sealed subs may be more musical, a vented sub puts out power. At my new place, it’s quite overkill. It’s coasting along at maybe 10% of its capacity. Nothing wrong with that. Power in reserve.

How do the Coherent Retro 15s compare to the Magnepan Magneplanar 3.7i? With the Coherent speakers, you’re sitting in first row, like it or not. And with the Magnepan speakers, you’re sitting 20 rows back, like it or not. With the Coherent speakers, the treble is crisp. With the Magnepan speakers, the treble is silky smooth and extends into the air. With the Coherent speakers, you can hear where the left and right speakers are. The centre image is stable and focussed. The soundstage is contained between the speakers. With the Magnepan speakers, it’s harder to heard exactly where the left and right speakers are. The centre image is diffuse. The soundstage extends far beyond the edges of the left and right speakers, and the depth is awe-inspiring. The Coherent speakers are ever-present. The Magnepan speakers are ever-distant. With the Coherent speakers, the midrange is detailed and palpable. With the Magnepan speakers, the midrange is detailed and recessed. With the Coherent speakers (without the sub), the bass is articulate and light on its feet. With the Magnepan speakers, the bass is, well, different. The Retro 15s will play all types of music: from heavy metal to Lieder and from Bruckner’s symphonies to Woody Guthrie, they will perform. Despite what some aficionados say, the Maggies do not like Motorhead. I found that, with the Maggies, I would listen more to choral and symphonic works. The Maggies are good at recreating the empty space around the instruments such as the interior space of a cathedral. But their ability to do this comes at the expense of recreating the exciting and visceral punch of rock music. With the Coherent Retro 15s, I found myself tapping my feet more often. With the 3.7i, I found myself cranking up the volume and closing my eyes more often.

Frank hasn’t been the only audiophile interested in the Radian coaxial drivers. Live Act Audio out of Germany uses the same driver in their Emotion and Reference Series of speakers. The Emotion Series employs one coaxial driver in a ported box. The Reference Series employs a single coaxial driver with multiple bass drivers. Their Live Act Series 115 (LAS 115) is the closest model to the top of the line Retro 15 from Coherent. Front instead of dual rear ports. Similar size. Full floorstander, as opposed to the Retro 15, which sits on a compact 7″ stand. But while the Retro 15 retails for $11,165 (demo model, includes delivery), the LAS 115 retails for 29,990 Euros ($45,000 CAD). I don’t even want to know how much Live Act Audio’s top of the line Live Act Series 512 costs: it employs four 12″ bass drivers with a single 12″ Radian coaxial driver in a 2 – 1 – 2 configuration. I’m sure it sounds great. And I’m sure it goes for six-figures.

Though Coherent Audio is a small Canadian company run by what seems like a husband and wife team, local audiophiles seem to have heard of their speakers. The reason may be that there is a huge (well, huge by audiophile standards) following for Tannoy dual concentric speakers. The offerings from Coherent Audio offer a very viable and attractive alternative to purchasing used Tannoy speakers. The pair of Ardens I auditioned, for example, must have been 40+ years old. They had new surrounds put in at Sound Hounds. The cabinets had been reveneered and in great shape, but nothing like the beautiful fine furniture finish Coherent offers. For example, the Ardens have wood veneer sides, but sport a plain black front baffle. The Ardens were going for $3000. I offered $2800, but the owner wanted $3000 firm. And I’m sure he got it. In a way, I’m glad he didn’t accept my offer. Now I have the mighty Coherent Retro 15s. But if he had accepted my offer, it wouldn’t have been all that bad. The nice thing about vintage is that you can enjoy the speakers for a few years, and turn around and sell them for the same price. Rob at Q-Electronic has also heard about Coherent Audio and the Radian drivers. He’s going to come by for a listen one day. And if he likes them, he’s going to build a pair for his own use at home. Radian drivers are a hidden gem in the audio world.

Here’s a photo of the speakers in the listening room:

The Listening Room at the Global Warming Villa
Front baffle, comes with magnetic bezel around the driver
Dual ports on rear, note how the binding posts are perfectly flush with cabinet

These speakers sound great and look great. Frank is superb to deal with. My biggest worry was the shipping. But it turns out my fears were misplaced. They were professionally packaged in a box within another box. Both speakers were attached onto a single pallet and shrink wrapped. It was a joy to unpack them, as much though had gone into protecting them on their journey across Canada. I’m glad I went to TAVES 2017 to hear these speakers. Although they’re slightly off the beaten path, Frank exhibits regularly and it’s easy to find him. I’m a very satisfied customer.

PSi #25 2019: “Elasticity”

School of Creative and Performing Arts, University of Calgary
Calgary, Alberta, CANADA
July 4 – 7, 2019

Extreme fluctuation is a basic aspect of life in Calgary. Situated between the foothills of the Rocky Mountains and the plains of the Prairies, nestled in the bed of the powerful Bow River, Calgary’s landscape is perhaps the most visible manifestation of this characteristic. An elastic and resilient ecosystem is demanded of an environment where springtime flooding is followed by prolonged draught and wildfires in the summer, and where winter chinooks can result in 30-degree temperature fluctuations in a single day. This reality is well known to the region’s indigenous population, while settler cultures continue to acclimatize. The economy, political imagination, educational systems, professional opportunities, and performing arts industry follow a comparable pattern of highs and lows, fluctuating between plenty and scarcity. It is with growing concern that we recognize this defining pull to extremes reflected on a far larger scale in global environmental, political, economic, and humanitarian contexts. As polar oppositions continue to intensify, with ever fewer checks and balances in place, we invite the PSi community to address the demands that extreme fluctuation places on the elasticity of connective tissues/processes, as well as the available modes of response.

Elasticity involves the ability to be shaped by an external force and to return to an original configuration if that force is removed. It refers to the adaptability and plasticity of networked connections, and although elastic tissue has a snapping point, it is far more resilient than inflexible materials.  

We call for proposals of panelspapersperformance presentations and workshops involving scholarly and creative reflection on the subject of elasticity as it applies to a wide range of performance studies topics, areas and contexts. These include, but are not limited to:

– The performance of resource-sharing, from the transfer of nutrients in root systems to alternative forms of social organization
– Modes of resistance, resilience and revision within social, political, cultural and artistic dynamics
– Collaboration as adaptation in social and artistic organizational structures and processes
– Elasticity as personal, cultural and/or creative strategy
– Creative strategies and techniques that enhance neuroplasticity and their transferability to other domains
– The elasticity of negotiations between artist/performer and the public
– Performance space as a malleable factor, both for artist and public
– Indigeneity, reconciliation and performance
– Productive economies and creative practice
– Networking places, performers and audiences
– Cultural policies and global impacts
– How spaces, environments and climates shape social, political, cultural and artistic performance
– Design as the ‘stage’ for elasticity, resilience, recovery … the return from ‘breaking points’


We welcome proposals that demonstrate conceptual and/or formal elasticity – that is, which respect and reflect but also adapt and extend the established practices of traditional conference proceedings. Individuals and groups are invited to submit proposals within the following formats:

Papers: 20 minutes individual presentations (may involve performance elements requiring minimal technical support)

Panels: 90 minute curated sessions involving 3-4 pre-selected individual paper presentations (or the collaborative equivalent; may involve performance elements requiring minimal technical support)

Performances: 60 minute individual or group sessions, presentational and/or immersive/participatory in nature, involving modest performance technical support within a studio/rehearsal hall configuration. Can involve an optional, integrated lecture component.

Workshops: 60-90 minute individual or group sessions, facilitating experiential knowledge.

Alternate Formats: 20-90 minute individual and/or group sessions adopting alternate, site-specific and/or experimental approaches. Venues and support are to be negotiated with the conference organizers.

Proposals should be maximum 300 words in length, in addition to the following information:

Name(s) of presenters
Geographic location
Institutional affiliation
 (if any)
Email address and phone number(s)
Technical and venue support required/requested (as detailed as possible)
Short Bio(s) for each presenter (maximum 50 words each)

Please note
: while the final abstracts will be published in both English and the original language of participants, we request that proposals be submitted in English.

The deadline for submissions is Friday, December 5th, 2018. Please send all proposals to, indicating your choice of presentation format in the subject title (for instance, “ALTERNATIVE” or “PAPER”).

For more information, consult the PSi#25 website at Additional information regarding registration and accommodation will be posted to the site shortly.

Well, Calgary is an awesome city. I was there earlier this year speaking at a conference hosted by the Department of Classics and Religion at the university. I had a great time. The city is actually quite multicultural, not at all like what I had thought. In the downtown core there are fantastic skyscrapers. There’s one “Bow” building that’s curved like a bow. The building is supported externally with a criss-cross of metal columns so that the inside is wide open and expansive. Cool. To get around in the winters, there’s a series of walkways that connect all the buildings downtown so that you can literally walk from one end of town to another without having to set foot outside. I like well thought out schemes like this. And the conference theme of “elasticity” looks promising. Many of the papers might be on the future of drama. Or so I hope and imagine. It all looked so good that I put in a paper proposal. Here it is:
Tragedy’s Masks: The Elasticity of Tragic Theory from Aristotle to Today
Interpretations of tragedy fluctuate from one extreme to another. Averroës translates tragedy as “eulogy” or a poem of praise. To Albert the Great, however, tragedy amounts to a recitation of dirty deeds. This paper examines why, unlike the terms philosophy, history, and comedy (which also derive from ancient Greek), tragedy is an elastic term. It provides examples of how this elasticity allows literary theorists to come up with fruitfully ambiguous interpretations of tragedy and concludes by proposing an exciting new interpretation of tragedy.
Because the term tragedy is elastic, tragic theory is a product of its age. In ages interested in final causes, tragic theory focusses on teleological interpretations: the goal of tragedy, according to Aristotle, is to elicit catharsis from the audience. In a Newtonian age full of motion and equal and opposite reactions, tragedy becomes a dramatization of colliding moral forces, as exemplified by Hegel. And in ages interested in psychology, tragedy becomes a battleground of conscious and unconscious drives, as exemplified by Nietzsche.
Today’s world is increasingly interconnected with the result that local bets carry global implications: think of the Great Recession, Fukushima, Deepwater horizon, artificial intelligence, and gene editing. As such, there is a popular fascination with risk: what happens when low-probability, high-consequence events derail the perfect bet? Theatre can tap into this fascination by reimagining tragedy as a theatre of risk. In the risk theatre interpretation of tragedy, heroes’ best-laid plans are upset by low-probability, high-consequence events such as Birnam Wood coming to Dunsinane Hill. To see how this new model of tragedy works, the writer has teamed up with Langham Court Theatre to inaugurate the 2019 Risk Theatre Modern Tragedy Competition, the largest playwriting competition in the world dedicated to the writing of tragedy (see

Edwin Wong received a MA in the Classics from Brown University, where he concentrated in ancient theatre. He is currently finishing a book on tragic literary theory, The Risk Theatre Model of Tragedy: Gambling, Drama, and the Unexpected. He lives in Victoria, BC.
Fingers crossed for an email accepting the proposal. Then it’s time to take risk theatre back on the road!
