My basement theater room is 23' long, 12' wide and 7' high so ~1932 cubic feet. Only one opening to the room that is open and this open could possible be covered by some material during viewing times. I am planning on getting the 16-xx Plus series. Whether i get the PC+ or CS+ with the sampson amp relies on me needing a second sub. So on my room size, do you think i will need a second sub? BTW, I am pretty bass hungry.
