Considering buying my first ever subwoofer. I've heard great things about SVS and am compelled by the review of the above model here. I'd like to use this for both audio and home theater. Is there anything I need to know about this type of set-up? My room is approximately 20' x 15' with an "L" shape on one end. My system includes a Yamaha RX-V992 receiver and (the now defunct) Platinum Audio Studio 1 mains, Studio 2 center and Studio 3 rears. I know I have a lot to learn, but thought I'd ask for some preliminary advice. Thanks!
