I purchased the Polk Audio RM20 surround speakers and a PSW-111 Sub for $582 taxes in, i was looking to switch it for ths SVS sbs-01 5.1 system but the cost is $1150 plus taxe here in Canada, is ths SVS that much better, the room is 12x18x9 and it will be powered by a pioneer elite AVr at 110 watts per channel. Comments are welcome.
