Short reply as things here are busy BUT I received my LFM-1 today ( was quite surprised ) and have it hooked up. I have only done a very simple calibration but could not resist getting it connected. Also, please realize I have limited subwoofer experience and reference points ( have never heard an SVS, HSU, etc ). But, here goes:

It's fairly big though not huge. The plexi top looks very attractive and it also passed the girlfriend test for aesthetics.

How does it sound? IN technical terms.. simply WOW. The Two Towers has never sounded so good. The bass is very strong and deep but never boomy sounding. I've also played afew cd's with it and it perfomrs just as well with music in bypass mode as it does with HT. It easily shakes my walls, and on moderately loud settings ( -20 db on my 950 volume ) it makes my sofa vibrate when the deeper bass sections occur. I was a little concerned about musicality since I love 2 channel music as much as HT and thus far there is no signs of boominess at all, but it does have very powerful, strong, deep bass. Yes, I'm happy thus far. More to post after I have had a chance to play with it more but for now it's a very incredible beginning!
