I have no doubt that the Walsh driver stomps all over Maggies, which are the best selling "audiophile approved" speaker in the world. As such, i'll use them as a point of reference.
By re-designing the Walsh motor structure and suspension, thereby making it more efficient and higher in nominal impedance, you make it easier to drive. As we all know, Maggie's aren't the easiest to drive and are also "finicky" when it comes to placement. In this regard, the "modernized" Walsh walks away from the Maggie.
On top of that, the Walsh's have TREMENDOUS bottom end, something that you couldn't pry out of a pair of Maggie's. In this regard, the Walsh RUNS away from the Maggie.
The Walsh's also have the deepest and widest dispursion of any driver / speaker system that im aware of, making for a FAR more "engulfing" musical experience. One can gain the sonic "wrap around" feeling that one normally only obtains from listening VERY nearfield, a presentation so "thick" that it feels like you're walking through it ( varies with recording ). Compare that to the presentation of the Maggies, which sounds "ambient" and "spacious" only when sitting in a limited area, and the Walsh once again wins.
Given the single driver point source with no crossover parts to soak up power or add their sonic signature, you don't have time or phase errors. The "one driver, direct drive" approach also produces excellent harmonic structure, prat and coherence, as many of the "full range" afficionado's will testify to. Maggies have a crossover, use multiple drivers and lack the warmth and bottom end required to have great "prat" ( in my opinion ).
To sum things up, it is a fabulous driver with GOBS of potential that absolutely kills the "audiophile reference". Would the average audiophile recognize this? My answer is NO. Most audiophiles are sheep and led by their noses via printed reviews and the herd mentality of the internet. Even if the glossy rags and internet "herd" were to jump on the bandwagon, it would be a short-lived ride till the "next best thing" comes along.
Most audiophiles are more concerned with dimunitive size in a speaker ( monitors ) OR MEGA sized boxes with a lot of drivers. Maggies are kind of a cross of these two i.e. large frontal section but very "petite" in terms of depth. On top of that, the Walsh's are so unconventional in appearance, operation and placement that many would be turned off.
As such, i think that it would become a niche product, just like those using SET's, single drivers, nearfield listening, etc... That's because the design approach and presentation wraps up several different aspects of what these people love and are after, all into one package. As we all know, those specific types of listeners are but a small part of the audiophile market, which is why i think it would be doomed to remain a product of interest to only a select few. Much like it is now, but on a slightly wider scale. Sean
PS... To be honest, i've never heard a Heil system that was worth listening to. Having said that, i'm quite certain that the installations and support componentry were to blame. This is probably most of the problem with those that had complaints about the Ohm's too, especially "way back when".
The technology behind the Heil driver, much like the Walsh, is pretty incredible as compared to more conventional designs. It's too bad we don't have any designers / engineers around today that are willing and capable of introducing and properly implimenting "ground breaking designs" like these. Instead, we keep getting re-hashed "monkee coffins", albeit better designed and better sounding "monkee coffins".
