Brian (or anyone else),

I was wondering if I could get a bit of advise on subs.

I'm in an approximately 3700 cubic foot room, but will have a "near-field" sub placement (sub directly behind couch on one side directed in - me sitting on the couch ~ 5ft away). Though my room is large, my entire 7.1 setup is on one end (one, 1/3rd of the room), and I don't really care about the sound performance on the other 2/3rds of the room.

Would a 12" be sufficient without anything nasty (like clipping) for up to about 100db? Technically, I have space for the 15", but I'd really prefer to not go that large unless you just think that's what I need in my case? FWIW's, my SB12+ doesnt have any issues playing to my demands, but I believe it has a bigger amp? (425 bash)

Also.... I own a SB12+. Are you pretty confident that when I compare your sub to my current one, that the end result is that my SB12 will go on ebay, and I wont return the Rythmik? :-) To be real, could I tell a difference? I do have a HSU test tone disk, btw.

Thanks,

Az.
