I have an opportunity to purchase either of these speakers at a fantastic price, but will not be able to listen to either due to a lack of stocking dealers in my area.

I am considering the RBH signature 661se CLRs for the fronts and center and 66se surrounds for the rear, or the Klipsch Reference RC-7 Center, RF-7 fronts and the RS-7s for the rear surrounds.

This will be a dedicated home theater system as I have a seperate system with Maggies for music. I will be powering the system with a Carver AV-705 (125 x 5), so I don't think that efficiency of the speakers will be a deciding factor. I already have a SVS PB2+ sub (man, what an earth mover!) so the low end is covered.
