"Polyamping" A Look to the Future or Fancy Fad?


In a recent quest for information regarding DIY speaker designs, I was referred to the Linkwitz Orion Project. These speakers employ active crossovers and it is suggested to give each driver its own, separate amplification (actually one for each woofer and one for the tweet/mid - three per speaker). Linkwitz recommends the ATI AT6012, a twelve channel, six zone amp (60W/ch). I am not sure about the merits of the ATI amp but, regardless of amp, does anyone think this will be a "growing" design. I mean I have heard the benefits of biamping and have heard tell of triamping but, in this case, "sextamping"? Octamping would seem to be next. All accounts say that the Orions sound fabulous. Perhaps I am just behind the curve. What so you learned folks think of this direction in audio?

Some interesting comments.

Bob, I was not singling out that an ATI amp be used, just that such was sugeested in the design by the designer. I have no knowledge of these amps personally. It was the only design in the DIY realm that I saw which incorporated use of a mutli-channel amp.

Sean and Gregm, your comments with respect to sufficient power are intriguing. How would the 60w not be enough for quality bass response when others claim to get such even with very low wattage amps? I am not saying you're wrong, just asking because I don't know.

Sorry if I overlooked designs of the past that used this design scheme. It was the first I've come across that really went beyond biamping in what seemed to me a radical way. But then, I haven't been auditioning dozens of speaker designs over dozens of years. Because Linkwitz is considered to be rather an innovator, I wondered if his design might be a direction for the future. If such has been done before, though, it wouldn't be the first notion of a technology or approach in audio that was relagated to "dinosaur" status, only to raise its head triumphantly at some point in the future. I'd say analog front ends are an example that many here are familiar with.
Well I made up the label "polyamping" for the purpose of this thread title though, like you say, there is nothing new under the sun so I won't claim it as an original idea. Nor will I claim, or even remotely infer, that I "invented the whole thing". Had I the technical expertise to do so or the stones to claim such, I wouldn't be here asking questions.

Has anyone taken a look at the Orions under the link http:\\www.linkwitzlab.com who would like to comment on whether it seems a reasonable approach?
Kpinneo, wow I had forgotten about this thread. I'd have keen interest in your impressions of the Orion project you build.
