hey, i got the JBL NSP1 set several months back. but now i want to set up another system for music only using 2 speakers and my old receiver. lately i've been leaning toward using two of the N24's for this music only system. if i do this i will be using my old jensen speakers for the rears in the home theater system. will this be ok? i know for sure the front 3 speakers need to be voicematched but what about the rears? thanks in advance.
