Have you tried treating the room yet? Look around for "Do It Yourself" types of webpages for acoustic treatment.

One thing I would try is to take a thick blanket or tapestry and hang it above the drumset. Tack it into the ceiling so that it's centered over the cymbals and let it drape down a little bit. It would have a convex curve off the ceiling. Kinda like this (side view)

but obviously more rounded. Leave the sides open (attach the top and bottom sides to the ceiling leave the left and right sides open. If the tacks/nails are strong enough, you can try to fill it with some sort of light material (fiberglass, sponge, foam, etc). Try Adjusting the amount of draping it has (a couple inches off the ceiling to a foot or two off the ceiling at the lowest point). See what sounds best in the mics.

Theoretically speaking, the wavelength for a sound at 2KHz~2.5KHz is around 4.5~5.5 inches. So you should have the tapestry drape at least 5 or 6 inches off the ceiling to catch sound at 2KHz and up.


Hope this helps a little.
