Hi!
thanks a lot for all your suggestions!
Thanks a lot Paul for your job re-designing and modifying the current Xover.
It is nice to see all you guys trying to fix my problem.
I don't know yet how to proceed but I have a lot of choices now.
Thanks again
Giuseppe

The Tweeter and Mid Closed box, not filled, just foam around the walls

Experiment: Add loose stuffing in the rear 1/3 of the midrange triangle box (wool, fiberglass, cotton, poly-fill). Most speakers put sound absorption material in the rear midrange cabinet volume to absorb highs.
