I have some reading to be but I will be setting up a second sub SOON
I now have a denon AVR 3805 Velo SMS-1 with one SVS SB12 + and will be adding a second SB12+
I have no problems with HT but I like a lot of lows and when I turn up my sub I can tell its coming from the front right of the room
So I hope adding a second will help even out the lows in the room
