Due to the fact you're dealing with laws of physics it is possible to do. First is the bass traps. The more the better. This will level out your bass frequency response. Next is some sort of DSP. Of course speaker position should be experiemented with. AV123 has recently come out with a parametric equalizer to deal with this effectively. I'd get ahold of John Casler and ask him. He has been experimenting with one I believe in his system learning about it so he can help others. They're only 400 bucks and I'm not even sure if they are available yet. Get the bass smoothed out some and your midrange will sound much better. I know it sounds (not intended) odd but it is surprising how much better your whole system sounds with the bass response flattened. First reflection points like the ceiling, sidewalls and any coffee table should be damped or diffused too. You can make panels that can be put away when you're done listening if need be. When you have a good acoustical environment it should sound very close to an actual performance on many good recordings with those RM 30's.
See what you've gotten yourself into:) Now you can't stop!
