I'm using NHT Focused Image Geometry speakers (2.3As, 2.1s, 1.3As, and SuperZeros) in a 7.1 channel setup with two Rotel amps -- a 5 channel 985THX Mk. II (110 x 5), and a 2 channel 981 (130 x 2), and I'm very pleased with the sound.
I've never heard their theater line, but if they work like the Focused Image line, the more power the better. I had my 2.3A mains hooked up to a Denon receiver, and there was no difference between running them full-range or crossed over to the sub -- the Denon couldn't make them produce ANY real bass at all. With the Rotel 981, they actually get down around the 40 Hz that they're supposed to reach.
