Try putting the speakers on pads. I use Aurelex speaker stands. The rise about 1-1/2 inch off of the floor and are great to reduce any bass reverb/boominess. It also goes without saying (but I will say it anyway) to move the speakers away from the walls a bit more. They are, I think, front loading speakers so perhaps that is less crucial.
The stands are available on Amazon and elsewhere online and at stores as well.
