System: Recvr.: HK AVR125, DVD Apex AD-600A, TV Sony KP- 53S15, Fronts: Sony SS-MF315, Center: Infinity CC-1, Sub: InfinityBU-2, Rears: Polk R15. Sub is se inbetween theleft front and TV. Room size is 12' x 36', min listening area is 12'x18'. 8' ceiling. I know this is a lower end set up but I'm happy with it. I was hoping for input on the best way to set up the speakers. Large vs. small plus output levels? Any help or extra thoughts would be greatly appreciated!
