You could try rotating the driver 90 degrees so that the problem area is at 12:00, and MAYBE gravity will help. If that doesn’t work, you could also try it with the problem area at 6:00. This is a long shot.

I been rotating drivers for over 35 years but 180. A guy told me to do it every couple of years, and do a batting inspection on the drivers. His drivers were larger than most, but with care and rotation, 40+ year old drivers used all the time, are still sounding wonderful..
Check and make sure something behind them hasn’t come loose, like the batting membrane, or the securements coming loose.. Even floppin wires vibrate on the enclosure, drivers... LOOK..first
Happy hunting, hope it’s something simple like, SOMETHING simple.
Regards
