I have a few questions that would be great if they would be answered, would really help out....first I'll give some background In my fraternity house, we are setting up a speaker system in the dining area, a very large room. We have located the receiver in one corner of the room, and we want to put the 4 speakers and 4 powered subwoofers in each corner of the room. How can we hook up the 4 subwoofers efficiently? I hear that if you go over a certain distance you lose signal. We need to go around 65 feet to reach the far corner. Can we split the signal so that we don't need to get multiple long cables? Thanks for any help!
