Romy, have you gotten into where/how your MF driver breaks up yet? Given that the tweeter is actually made to go way down there, I am curious if this may be a case where 1st order XOs at 1 octive apart could work. Or, if not, at least trying it might add to your sense of what's going on in the area you are concerned with. If you stuck with 4.5k Hz like you suggested, and 2nd order on top, then maybe try 3k/6k, both 1st order. What the heck...
And did you ever put some sort of soft/hard de-coupling washers on the driver mounting bolts? Depending on the size of those screws, composite T-washers may be available that would allow you to isolate the screw and nut from the driver frame and baffle. Use fine pitched screws and a drop of Loc-tite resin on the screw (or use locking-type nuts) and you can very precisely dial in and hold indefinitely a given tension that will best damp particular resonance(s) at that level.
Best regards,
