You do not need an AVR with separate sub output to get the benefit of REW. You will not actually physically move the subwoofer. You increase the distance setting and that time and phase align the subs and speakers and improve your FR if you have a dip/cancellation in the FR.
Ideally, you would first turn off Audyssey and then move the sub or subs around the room and try to get the smoothest FR. Then run Audyssey, then run REW and look at your FR and most of the time you need to increase to subwoofer distance in your AVR settings increasing it by 1-2ft and taking another REW sweep. Keep increasing the sub distance until you get the smoothest FR from 10-200hz.
