Heh, the LFM-1 can definitely supply the "hey guys" levels of bass...especially for people downstairs. 8-)

Like Gonk, I haven't heard the LFM-2 either. If the LFM-1 is blowing your doors off, you can always turn down the gain on it. I've got mine set on 2 and my listening room is many times larger than yours...

Cheers,
