I have a Denon AVR-2307Ci with Polk Monitor 60 (L/R), CS2 (center), f/xi3 (surrounds), and a self powered PSW 404 sub in one room; and another Denon AVR 1600 powering paradigms with a 4speaker impedence matching control box. There are two speakers (in-wall) that are powered by the 1600 in the same room as the other system. Those two speakers as well as some outside are turned on/off with the imedence control box. Is there a way i can run those two in-wall speakers (from the 1600) while watching SAT/DVD on the AVR-2307 by connecting the two recievers? and if so how?....or would it be a better idea to re-wire the 2 in-walls into the the 2307 as Zone-2 7.1? Any suggestions appreciated!
