RM8/PSW111 crossover problems

I have a 3.1 system now with RM8 left/center/right, and just hooked up the PSW 111 (pre-out to LFE in).

I ran the Audyssey setup on my receiver (Onkyo TX-SR508) and it set the crossover at 120 Hz, which is seemingly where it should be (based on the specs and all the reading I have done on here).

Problem is, everything at the top and bottom of the spectrum sounds great, but the middle is missing. It seems like the volume drops off so much that you just don't hear the sounds that should be coming from the lower range of the RM8's.

Would raising the crossover to 150 Hz fix the problem, or is that too high for the subwoofer to be dealing with?
