My new LFM-1 Compact arrived on Friday. I got it set up and configured. I ran the Audyssey for my Denon again using 6 different points. I sure that they are plenty of subs that can go deeper, and cost more, but this thing is a huge step up from what I was using. My wife could even tell a big difference, and she can never see or hear what I hear. The bass is way more tighter than anything I have had before. It is clean with no boomyness. Watch part of the Eagles from Melborne DVD. The kick drum was pounding my chest. I really believe that if I had went with a larger sub, it would have been to much for my listening area.
