Hi, I am really interested in getting an SVS subwoofer, but my main concern is which to get! ;-), My room is approximately 12x13X8 (8 = ceiling height) and the subwoofer will go with 4 Energy connoisseur C-3s and a center. I want to set my speakers to small so i can help my c-3s sound better and put all my bass in the subwoofer. Which series should i go with? the PCi or the PC+? Im not going to play it that loud (nor would i think i would need to due to the small size of my room i think) and which size should i go with? the 16-46, the 20-39 or the 25-31? I admit that i am interested in added subsonic potential added by the 16-46, but would that be alright for my C-3s and my room? I personally would like sub with the most capability., Any recomendations would be very helpful, thanks, -Chris- what sub would hit reference level in my room and what does reference level necessarily mean? I heard it a few times recently.
