They are actually matching stereo amps, two stacked on each side, providing 8-60w amps (mono speaking :-) total.
The 2-8" mid drivers of each panel are wired in parallel and powered by 1-60w amp; the tweeter by 1-60w amp; and each of the 2-12" woofer drivers by a 60w amp individually...that makes 4 amps to 5 drivers (on each side) of the stereo (2-channel system)
This is possible becasuse it is an active EQ/XO 2-way system. That is, there are 2-outputs from the EQ/XO for each side: one for the main panels, and another for the woofers.
Then I use 'Y' splitters to each stereo amp, and run a speaker cables to each individual driver (except the mids are joined together as one (wired in parallel) giving each its own amp.
I take it your goal for the system is not 'true to the original'. That is, revealing, transparent speakers, powered by a distortion free amp so you can actually hear what got recored onto the source material: the good, the bad, and the all too frequent ugly.
If you use your system to correct poorly produced recordings you are left out of hearing the sonic superiority of the well engineered ones. Oh, well.
To me, a 'poorly produced' recording is one where some arogant engineer attempts to 'improve' the sonic quality of the music the artists create on their intruments with their 1/4 million dollar, room size, mixing console toy.
Whereas others, gaining the respect of the more serious audiophile, attempts to capture with sonic accuracy what they are actually creating, complete with subtlety and vibrato, including the bass notes and drum slambs, and the invironment in which it is made.
That is what I want to hear: in the privacy and comfort of my own home. It is possible, you know.
