I was just wondering if anyone else is doing this i've got an Onkyo 5.1 multi source running my voice and a Marantz 4 channel running my 3 subwoofers. They are wired together through a 15 band a side graphic eq. Its a pretty loud setup and I have a ton of flexibility with two volume adjustments on the voice side (main speakers and remote speakers are both wired in the same room and have separate volume controls) and the volume adjust for the bass along with the option of 1, 2, or all 3 subs on at once or none at all.
