I'm having real trouble wrapping my mind around the idea of a single 12" driver having more output and impact than 4 SVS 12" Ultra drivers. My wife has basically told me to get what I want and shut up about the subwoofers but now I can't decide what to get. I want a sub that can do pipe organs and kick drums equally well. :-) That doesn't seem to exist in my price bracket. (About $2000) My room is every bit of 4000 cubic feet. I also don't want to mess with plugging ports because in my experience this has led to port noise that I was able to hear.

Whatever I get I have to be happy with for the next 10 years at least.

There's no place like 127.0.0.1
