Hello all,
I'm looking for a way to tame some of room modes in my theater room. I realize that the best way to do this would have been to build my room to better dimensions, but it's a little late for that now. (Should have done more homework up front. ) Here's a little about how my room is set up:

Speaker compliment:
Front: B&W DM604S3 Set to small, x-over @ 40Hz.
Center: B&W LCR600 Set to small, x-over @ 60Hz.
Srnd: B&W DM302 Set to small, x-over @ 80Hz.
R. Srnd: Polk M3II Set to small, x-over @ 80Hz.
Sub: HSU VTF3-MKII Built-in x-over disabled.

Electronics:
PrePro: Outlaw 990
Amp: Rotel RMB-1075
Srnd. Amp: Parasound HCA750
DVD: Denon DVD-2900

Room:
25.5'long x 13.5'wide x 7.5'ceiling.
Thick carpet + pad over concrete.
Large 5 seat sectional sofa.
Acoustic panels on rear wall.
Front speaker baffles 3' from front wall, slightly toed in.

My sub is 5.5' from the front wall along the side wall. This placement didn't give me the loudest bass, but it did give me the smoothest response I could get. I used a test DVD with a bass sweep and rat shack sound meter. I originally had the sub in the corner, but all I got was one note boom. So I'm looking to further tame the bass in my room. I was thinking a 2nd sub could help me wth that. I'd like to save some cash so I was looking into the LFM-2. Could this be a decent match for the setup I've listed above?

Sorry this is long winded. And, as always, thanks in advance.

later,
simp
