The ringing wouldn't change - it's very much a driver material, surround, motor characteristic. BTW. I already damped the baffle, the cup, and the back of the driver with dynamat. Stuffed acoustic fiber in the cups too. No more cavern reverby effect. Also used 1 layer TP between the pad fabric and front of driver. The TP worked better than other materials in reducing the 7-8k peak, while retain as much last octave air as possible. Measurements forthcoming. It sounds pretty darn good. Unfortunately, I don't think anything can be done to fix the bass distortion.P.S. I suspect using Jerg technology on the pads may yield some gains in reducing the 1k bump, smoothing things out, and providing a better sense of openness.
I do like these cheapy drivers a lot.
