You are right, and for larger rooms, it can be a bit of a stretch to get enough out of them when running the full range. I have run various pairs in the past bi-amplified with KT88's on the top and they are beautiful. Seeing as the Genesis amplifier uses the Hypex modules, you are probably getting excellent sound out of the RPDs run full range by them. The Hypex parts, are good stock and implemented properly are absolutely outstanding.

Yes, Bi-amping most speakers is where it is at. It makes it much easier to choose the right amplifier for the job.
