Play with sub positioning and phase adjustment.  You might be able to knock down that narrow peak considerably

I would recommend pulling your speakers well out into the room. Listen & measure as you move them. I would also suggest playing with toe-in after you pull them out into the room. Don't forget to mark prior speaker position with tape.

Quick question on toe in...right now, they are toe'd in right now to aim about a foot behind the listening position.  Would you suggest not toeing them in at first then starting to incrementally toe them in?

Check out this thread and see if it helps you at all. It's one method of speaker positioning used. There's a lot of information but read it through. There may be some ideas that will help you now.

Dguarnaccia, thanks for the update. Not being an audio expert or guru, I'm happy that I could be of some small assistance. I suspect that you'l be most satisfied running the mains full-range like I mentioned in #2 above, with the two subwoofers running up to 120 Hz region. You may need to parametrically equalize down a bit around 58-78 Hz or so. Also, it will be  a little tricky playing with the placement and phase for the subwoofers. The method discussed in http://www.mehlau.net/audio/multisub_geddes/ probably will be the easiest, but you'll probably want to skip the step with the subwoofer in the corner, unless you chose the corner where the tube trap is now. One possibility that might actually work for you would be to place the two subwoofers to the sides of the listening positions because these would likely maximally energize a different subset of room modes. For extra credit, you might consider running them 90 degrees out of phase for interesting "spatial bass" effects, as David Greisinger from Lexicon suggested. Best of luck, and have fun with your party!
