"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?

4yanx...Of course the idea of an amp for every driver has been around as long as I remember, and I go back to the early 50s. However, your invention of the term "polyamplification" is a great leap forward!

Hi all, glad to read all your inputs, especially as it relates to my current project.
I'm building the Orions, but am making what I consider to be significant improvements to Linkwitz' design. I do highly regard his designs and expertise, yet in researching the Orions for this project, it became clear to me that some improvement could be made in the area of baffle resonance, for example, and so I am taking great pains to isolate the Seas midrange and also dampen overall resonance.
My system will be:
Sony SCD-1 modded
Supratek Sauvignon linestage
Linkwitz designed active crossover
(2) Bel Canto EVO4 II (each driver driven by 120w)
Linkwitz Labs Orion Speakers
Chimera Labs CCC Litz-wound interconnects and speaker

I can hardly wait to see how this sounds. I won't be done with everything until May or so. I'll post with an update if anyone is interested.

From what are you isolating the mid?
Interesting about the baffle resonances. How are you thinking of doing this (bitumen sheets or...)? Cheers

Hey Sean, when are you going to build your ''System'' here and post some pics of the arrangment you just wrote about ?

Rgds.

Kpinneo, wow I had forgotten about this thread. I'd have keen interest in your impressions of the Orion project you build.
