I've owned these speakers for about 2 years, bought directly from RSL. They are absolutely fantastic speakers, far exceeding what I expected to get. I have them hooked up to an old Marantz SR8500 AVR, Sony 5 Disc CD player, and a Sangean HD Radio receiver.
The space is small, a 5'x12' fenced in back yard. Even at low volume, the bass is impressive. I'd call them warm, if only slightly. Details are there, they really sound amazing, especially...
