this is a great idea…!! never thought of this.. If we use just 1 Beolab 7.4 for center.. we only send Left OR Right…correct? We dont send both signals (L R) to this speaker. I ask because..i have a 7.4 that we make the RCA cable to powerlink and 12v trigger. We send BOTH left and right..but the speaker sounds very loud..more than the other speakers..i think we send double signal too much.
