So a receiver + stereo amp would not work. I am pretty sure that the power AND the gain need to be the same for all channels powering the new speakers


i'd be willing to bet that the amp for the rear section doesn't need to be as powerful as the front section. i bet only the gain needs to be identical. lets face it the rear only has 2 tweeters and 2 mid-woofers. the front has all of that plus 3 (sub) woofers.

time will tell


here is a quote from andrew, tonight, about the amp needs for the new speakers and the DSP boxes:

"The amplifier power does NOT need to be identical for the front and rear sections. A good rule of thumb is 60% or more of the front section power. An example would be a 200 WPC stereo amp driving the two front sections. You would then want at least 120 WPC for the rear section. Any less than 60% and you risk the rear sections running out of power before the front sections. Now, even though the amplifiers do not need to be identical in power rating they MUST have identical gain."

Gee, any of this sound familiar!?! Looks like Uncle Solarrdadd hit the nail on the head with the my thoughts on the amp needs! wink
