LFM-1 Great with Studio 20's
I have three Studio 20's (one for center), with the Outlaw LFM-1 sitting in the corner of a 15x15 room. And this system SINGS, baby! On music, I hear a low end that is clean, clear, and not forced. On movies, it can curdle your guts.
I have friends that have much more expensive systems, with much larger and costlier subs -- and when they hear my system, they always get a funny look on their face. (But I think they also have not taken the time to balance their systems).
So, for me, the LFM-1 is a good match!
