"I am sure that there is some form of damping which could be included into the cavity and on the driver basket which would go a long way to help it's just a matter of experimenting. I am sure some significant improvement could be found. "

I have done extensive testing with a wide variety of materials in varying thickness: acoustical felt, cotton, fiberglass, polyfill, lamb's wool.

None of them provide a "significant improvement", all of them are capable of reducing a peak around 170 Hz, but also reduce the output level below that by a similar amount, net result is just less output, with a similar peak.

And a day's measurement work, and a lot of cleanup after...
