A history of success
CM3 Transmissionline speaker
The first product
Bo Bengtsson's first product was a speaker called CM3. Over 24.000 units were sold in Scandinavia alone during a period of 12 years, which gave his company a 33% market share in the business segment for speakers in its price segment. Originally introduced in 1976, even by today's standard it was in many ways a remarkable product. It was the first series-produced transmissionline speaker in its class, utilizing a spin-off of the famous Decca Kelly ribbon horn.
The transmissionline concept made it possible to get more dynamics and impact than ever possible before in a cabinet of that size. One of the features that made CM3 unique was its capability to faithfully reproduce a square wave anywhere between 250Hz - 2,500Hz, indicating a phase linear response from 25Hz to 25,000Hz.
This was a step forward in the history of audio. To date, no manufacturer has succeeded in surpassing this capability. A speaker's inability to faithfully reproduce a square wave within this segment is proof that the fundamentals and the overtones in the music are not arriving at the same time. The solution to this issue has since become a trademark of Bengtsson's designs.
MEGATREND - the next milestone
Introduced in 1985 (at that time it was the biggest electrodynamic dipole speaker on the market) the Megatrend created a shockwave in the European audio world: never before had a speaker of this size been put into commercial series production.
A few years later, its two meter-tall dipole ribbon sister "Athena" was released. A speaker sporting an aluminum membrane only 9 millimeters in width and amazingly high SPL's with a quality only matched by the best electrostatics, suddenly was a available. Despite its relatively high price and weight of 250Kg/per pair (+500 pounds), over 40 pairs were sold in 24 months, finding their way to studios, record companies and the homes of music lovers.
Quotes from Megatrend owners/reviewers:
"Wonderful loudspeakers! They really sound terrific!"
"The best loudspeakers I've never heard! You only hear the music, - not the speakers. A shaking experience. I can't live without them!"
/Red Mitchell, NY
"I bought a pair of Megatrends for my studio and I am perfectly happy with them. They are truly addictive and it would be hard for me to do without them. The purity and the definition clearly is in a class of its own!"
/Robert Von Bahr, BIS Records
"Congratulations! For the first time I hear details in my recordings that I didn't even know were there!"
/Bertil Alving, Alving Records

EST - The transformerless tube-amplified electrostat
This project started up in order to be a reference standard for future loudspeakers.
By utilizing the best electrostatic panel on the planet at the time (the QUAD ESL unit) and by replacing the transformer in that unit with a proprietary no-compromise high voltage tube amplifier, our goal was to determine what was possible to achieve regarding no-compromise speaker technology. This project took place in cooperation with Uppsala university. It proved quite successful - so good that we initiated a series production!
Owners of these electrostatic speakers still keep in touch, especially when they need new tubes, which is in fact the only service related issue we experienced.
At that time, the EST system had very few competitors. This project served as a first-class reference and has been, until recently, the best mid- and high-frequency system project in which Bo was involved until the development of the Dynamic PropulsionTM and Ultra PropulsionTM projects.
Award Conferred by the Swedish Safety Council
In the mid-80s Bengtsson was awarded by the Swedish Saftey Council SAF-PTK for an invention in the electronic field. It is the spin-off from that invention that created the basis for his subsequent improvements in ribbon transducer technology.
The research continued and resulted in a new concept:
Hans Werthén with Centara Quadrant
One of the most famous industrialists in Europe, the former president of Electrolux, Dr. Hans Werthén, heard about Bengtsson's research into the ribbon speaker field. Together they decided to form a research company - Centara Research. Centara is an acronym for Controlled, ElectroacousticallyNeutral and TotallyAperiodicallyRadiatingApparatus.
The efforts were very promising and it was decided to develop a high SPL, square ribbon unit in order to be able to have a highly controlled dispersion unit that could be used for public environments. The result, Centara Quadrant, is shown to the left. With a radiating area of close to 1 square meter, Centara Quadrant can transmit sound over long distances. Its narrow dispersion makes it possible to precision-target the sound, like a spotlight in a theater.
The Centara Allegro Speaker Project
The results were promising, and a prototype with maximum dispersion, as opposed to Quadrant's minimum dispersion, was produced. By "cutting out a strip" of the Quadrant, (thus utilizing the line source effect) the Centara Allegro speaker was born.
On the basis of the research, a decision was made to produce a small pre-production series. At that time, Centara got an invitation from the team at the Beatles' Abbey RoadStudios to give a demonstration.
This was a real breakthrough. Until then, only JBL, KEF and Bowers & Wilkins had the opportunity. The demo was very successful and a dialogue began about how to custom-tailor the system for Abbey Road's specific needs.
However, simultaneously Mr Werthén started to get health problems so the project was put on hold. In the meantime, Bengtsson continued to work with the refinement of transformers for ribbons in general and Centara in particular.

A unique Picture
The first audio fair at which Centara exhibited was visited by none other than Michael Jackson's studio engineer, Bruce Swedien, creator of the famous Jackson sound. He got so excited at what he heard that he asked for permission to write his signature on one of the demo speakers!
Knowing where this man comes from, this signature is priceless.
...followed by consultancy work for a US elite company:
Cello Film & Music systems
The Cello Mini speaker
The Cello Mini
Ultimately, Bengtsson received calls from New York.
One was from Mark Levinson (the man), from Cello Film & Music Systems who wanted to listen to the Allegro. One pair was shipped, and the Cello team got excited. Bo was retained as a consultant in order to develop a true mini-speaker, utilizing his ribbon technology.
...in turn followed by consultancy work for Red Rose Music

The overture to the next speaker generation
In order to produce a speaker superior to the existing Cello system, Bengtsson created a new type of ribbon system, a system that became the forefather of the patented and patent-applied-for ribbon technologies that bear Transmission Audio's logo - Dynamic PropulsionTM and Ultra PropulsionTM.
Bengtsson's creations were successful. following are a few excerpts from reviews. (You will find the reviews in full by going to the links displayed below.)
"The R3's soundstaging was as surprising as its low-end response. This small speaker could fill the room with a really big, well-focused sonic picture—even well off the center sweet spot. I don't mean "big" for a little speaker—I mean BIG, thanks to the smooth performance of the ribbon tweeter, which appears to have remarkably wide dispersion.
..."What might you hear from the R3 when you listen to music? Small speakers are renowned for their ability to "disappear." The R3s didn't disappoint in that regard, but they "disappeared" in a particularly bold way. On my longtime reference disc, Mel Tormée and Friends Live at Marty's (Finesse W2X 37484), the Red Roses delivered an oh-so-vivid, airy, and effortless presentation of Tormée centered in 3D between the speakers, with a natural and convincing "edge" between his voice and the room ambience.
The R3s almost dared me to jump up and step into the image to see if it was solid. Jay Leonhardt's bass (or, on some tunes, Rufus Reid's), Donny Osborn's drums, and Mike Renzie's piano were equally well-rendered, though larger speakers deliver more "nightclub"—more ambience, more low-level detail from the rear of the room. But I didn't miss that stuff; what was there had that smooth, rich, three-dimensional, naturally-easy-fit Dockers sound."/End of quote Full review at: http://www.stereophile.com/loudspeakerreviews/350/
As Mr Levinson had no desire in participating in Bo Bengtsson's upcoming ultimate ribbon projects (the Dynamic PropulsionTM and the Ultra PropulsionTM technologies, Bengtsson terminated his involvement iwith RRM and launched his new technology that probably will set a new benchmark for reproduction of sound. Ultimately, Transmission Audio assumed all intellectual property rights and manufacturing rights of the M1 (the next generation of the former R3 now vastly improved). For more info, please see "Our Speakers".
The second speaker Bo designed for Red Rose was the R1. Even if that speaker is as obsolete from today's new Transmission Audio Ultra PropulsionTM speakers as the R3 is superseded by the M1, it nevertheless received favourable press. Bearing in mind that Bengtsson's opinion is that a new technology, in order to succeed, has to be twice as good at half the price it might be interesting to hear what the press had to say about the old R3 as well:
Quoting Soundstage "Y-files":
"This system is a certifiable knockout, both on sonic and visual grounds. I am floored with a broken heart before the end of round one. The piece de résistance are the speakers. Designer Bo Bengtsson has obliterated what previously were considered unavoidable artifacts of the ribbon experience -- narrow-dispersion beaming and low efficiency.
The beaming mandated head-in-a-vise listening to avoid the collapse of the center image, while the penchant for oodles of go juice meant arc-welding super amps that often lack in refinement what they carry in excess muscle. Think legendary Apogees of yore. They served as a sobering litmus test for self-assured testosterone-heavy amplifiers."
..."And while I have no clue how Bengtsson got around the former flashlight dispersion pattern of ribbon drivers to turn it instead into a broad-spectrum flood light, these babies have an embrace the size of a redwood tree. Even off-axis, the image stays centered. Mind-boggling stuff." End of quote. Full review at: http://www.soundstage.com/yfiles/yfiles200012.htm
A happy Mark with BB's first speaker
...followed by R1
Finally, the new, superior technology is born:
Transmission Audio's Dynamic/Ultra PropulsionTM
Born of 10 years' extensive research (an sample unit stands to the left) this is what the new technology is about:
1 - It replaces all current speaker technologies in price vs performance per dollar.
2 - It is more "ear-friendly" thanks to the extremely low distortion.
3 - It disperses sound in a near-180-degree pattern - no dead spots.
4 - The elongated form distributes the acoustic energy evenly, thanks to the so-called linesource effect.
5 - The combination of #3 and #4 considerably lessens the risk of hearing damage at high sound levels.
6 - Replaces much bigger systems in a typical installation.
7 - Maintenance-free.
8 - Can be used in all surroundings, be it home theater, audiophile use, studio or huge PA-installations.
9 - Extremely long life span.
10 - Ribbon modules can be stacked in up to 8 meters high to cover any room demands.
11 - Ultra PropulsionTM is a transformer-less true metal ribbon technology, the only one of its kind in the world, patent-applied-for and pending.
12 - The ribbons' performance is not impacted by extreme temperatures. Same performance from -50 degrees to +75 degress Celsius.
13 - Low production cost benefits the end user.
14 - Currently available in 4 speaker models, shortly to be followed by a modular high-quality public address system
15 - Tremendous market opportunities.
It is our firm belief that its important to release a new technology when the time is right and the customers asks for it. GOOD BUSINESS to us means making people happier when they listen to their music!
