OK, my friend with the two LFM-1s just called me with some more info on the new sub: a little more powerful amp (maybe 50 watts more), slightly different enclosure, called LFM-1 Plus, priced around $700, comes with port plug, bass extension switch bring it down to 20Hz.

What separates from the Hsu version is that Outlaw's believe in downfiring ports, which will usually fire into a nearby carpet/floor, cutting down on chuffing compared to a back firing port that fires into the air. For listeners, it basically means less port noise complaint (as Philip Roth would say).

My friend is tempted to buy two of the Plus subs at the show (to go with the two LFM-1s he already has). Peter said he would sell them to him Sunday evening.
