Dean, thanks for that breakdown. At $200 it might be a worthwhile investment once I get into my new place. Then again, that $200 could go a long way towards a very nice sub upgrade... hmmm, decisions, decisions. I guess I'll see what the neighbors are like, and then make the call.
As a side note, this is gonna be in a hell of a small room. About 10x9x9, so I could probably get a pretty small sub and still have a huge effect due to room gain and characteristics. Thankfully the room will be dedicated to HT and music.
