Jarred,
My room is 15 X 25..and I run 2 LFM-1's and a Def Tech PF15TL.
This does a good job on the bottom end.
I like solid controlled bass..that is why I kind of went overkill. I personally think it it better to have too much and turn it down...then over drive to get the results I want.
Just my 2 cents worth.

Later
