What kind of floor is under your speakers? Are they on an upper level? Are the floors suspended plywood? if you jump up and down does anything in the room pick up vibrations?
if so the problem may be inherent in your room/floor. Some speakers may isolate from floor interactions better than others. One cheap solution worth trying is to put teh speakers on isolation pads. I use Auralex subdudes under my OHMs on my second floor where this is a problem as it is with much modern constructed houses. A problem for Hifis and speakers but the give is good for avoiding structural damage in earthquakes, etc. Subdudes, if practical for use under speakers like yours, run about $50-$60 each on Amazon.
BTW when I use teh same OHM speakers in my basement on solid concrete foundation with thin carpet and padding, nothing else is needed. I can jump up and down all day down there and not much will vibrate. If I really turn things up, the walls and doors might just a bit, enough for the key I store above teh door frame to eventually fall to teh floor. Nothing particularly audible though. The same speakers off teh same gear are able to shine right through becasue there is little or no vibration transmitted to teh floor.
You might want to try some kind of isolating platform under teh speakers if you think you have this problem first before investing megabucks in other speakers that may solve teh problem in a similar manner out of teh box.
Just somefood for thought.
