Have you tried some form of absorbtion or reflection panels behind the speakers? I use some heavy wool rugs behind mine and the speakers are about 18" from the front wall relative to the front of the speakers.
I've had Tonian Labs TL-D1s (which are semi open baffle) and now have Clearwave Duet 6 monitors (which are rear ported) and have no undo bass reinforcement, muddiness or bloat. In fact, the Clearwaves measure +/- 2db from 1Khz down to 40Hz.
I'd experiment with some room treatment before giving up (if you haven't already done so) :-)
All the best,
Nonoise
