I got the LFM-1C and am driving it with the RR 2150. Sounds good for music in a fairly bright open concept living room+dining area+kitchen (hard to measure -- say between 400 (immediate sitting room) to 1,000 (neighbouring space) ft2). My experience is posted in the RR 2150 forum.

Basically: Solid base, not boomy. Fills the space well. The LFM can migrate under some conditions (i.e., my cranking the volume), but is generally fine on the plastic spikes + ceramic discs on hardwood floor.

Like Bob A's experience, discs weren't included in my package - had to request them, and they were sent along later.

And I remain quite pleased with the Outlaw products.
