Hi MikeW,
I'm a newbie with the same receiver and RF IIIs (older center and surrounds i'll probably upgrade soon) and have been wondering the same thing, so looking forward to any answers, including how you've set your system. On the home theater forum there's a lot of discussion about setting the speaker sizes to small and the sub crossover on the receiver to as low as possible, >60hz on the DB840.
