I agree with Plate. In my mind, you have 3 options:
1) Get a Tact room correction unit. It works exactly as advertised.
2) Try positioning the speakers along the opposite wall they are on now (ie if on short wall now, put them along the long wall).
3) If they are ported, try stuffing the ports with something like dacron, etc
As an aside, I am sure Mr Joseph could help you out as well. Best of luck.
