Judging from the info that you've provided and doing some "guestimation" ( appr. woofer height ), your bottom woofer is located at a height that is "safe" above 200 Hz or so. Since you are running it below that frequency, i would not doubt that your problems are resultant from floor borne reflections. Cancellation between the sub and mains is another concern, but i'm assuming that you have also experimented with sub placement to a great degree.Since the woofers are running full range with their own natural roll-off slope taking care of bottom end attenuation and your desire to keep the tweeters at a specific height, you may need to walk the speakers back towards the wall slightly. If you have gear mounted between them, it may affect the imaging and soundstage of the system negatively though. With that in mind, here's another simple yet STRANGE looking approach.
Take a piece of wood that is appr. the same width as the baffle board. Prop it between the face of the baffle and the floor. By altering the angle and length of this board, you can "fine tune" the amount and frequency of the reflections. This is strictly a trial and error method and does look a little weird when all is said and done, but can come in VERY usefull in situations like yours. Keep in mind that this can alter other aspects of the speakers performance, so try it with a grain of salt. Once you've found something that works to your satisfaction, you can go about implementing cosmetics from there. Sean
