Does it matter if the wire runs are equal? My front left and rear left will be about 15' father from the reciever than the rights- a buddy told me, I need to have the same distance , in wire to both, for optimum sound??? I have the Onkyo 5100 with Audesy will the eq system correct this ?
Thanks Much

Not necessary. Differences in length under a few hundred feet won't matter if the cables are otherwise adequate.

Thanks Kal
