I decided to buy Epos ELS-3 as main and center channel speaker. What would be the best matching rear speakers and subwoofer? I think I can buy additional pair and use it as rear speakers. But, I would prefer to go with another brand (possibly, the one designed for rear surround speakers). I got a lot of posts regarding subwoofer in this forum. If my room size is 16x15 and don't want to bother my neighbor, which brand/model would be suit for me? (I got Onkyo NR801 receiver) My budget would be $500-600 combined. Also, where would be the ideal location for subwoofer?
