Don't know if it's been mentioned, but you could try placing them on soft footers (I usually recommend first trying something from around the house like cutting up an old mouse pad/rubber mat, et cetera).
Does the Rotel's LF boost (6dB @ 100Hz) help?
As far as moving the speakers goes sometimes just a few inches will make a difference.
