This is my room layout: The red are the two couches. The green is where the TV would be. It's not EXACT placement but you get the idea I currently have a 2.1 setup. Sony STR-DG800 receiver Polk Audio R300 x2 Polk Audio PSW10 subwoofer What do you guys thing I should do? A 5.1 would be nice as I like the rear sounds, but the layout doesn't exactly make that all that feasible from what I understand... Should I go to 3.1 and get a center channel? I don't know what to do... please help!
