I am moving into my newly built house in 4 weeks and need to starting ordering components for my HT room. I've been really interested in this SVS box sub for some time because of all the rave personal reviews. Here's my thing. My HT isn't going to be built for an audiophiles ears. I want great sound, but probably wouldn't be able to tell a huge difference between whats awesome and whats just pretty good. So....my center channel and surrounds are of the JBL studio series line (S-CenterII and 4 S36II's) and are going to cost me roughly $600 for all. This SVS sub with the color I want after shipping, is going to be $700! I want great bass response but am on the fence as to whether this sub is that much ahead of say the JBL S120PII, or the PB12. Is the SVS THAT much better or am I better off saving my cash? BTW, the room the HT is going in is only 12x13 feet. Thanks!
