I finally figured what was causing me to have such bad results with the FV15s. When I hooked up the first sub, it had the factory defaults set to the settings I needed so I assumed the second one was going to be the same. It did not and it had the PEQ turned on. So I was running the two subs with basically different settings. I tried it again with the recommended settings from Brian, and the results are now WAY better. I also moved the center speaker to make it more flush with the subwoofer and that seemed to have improved things a little.
For movies, the FV15 sounded better across the board compared to the F15s. I attribute that to the difference in the output between the two. I have the damping set to HI for both movies and music. For music, the F15s is still a tad better, I would grade it at a 9/10 and the FV15 at an 7.5-8/10.
So far I am very happy with my purchase. I think it is a good all around compromise given my 90/10 ht/music preference. Thanks everyone for your thoughts and suggestions.

dynamic EQ on
Audyssey music (even for movies)
Try Audyssey with 14-hi (rather than 14-low, like Brian suggested), so Audyssey can correct for phase. I think the problems Brian was troubleshooting don't apply to all rooms.
Try a variety of crossover frequencies with mains. I got best results with my left/right at 90hz and my center at 70hz. This gave my LRs a bit more muscle while avoiding unnatural boominess in male voices. YMMV.
