The dust cap is sometimes the source of higher frequencies which the large cone cannot follow. Same idea as a "whizzer" cone. And then there is dust to worry about.
Better replace the dust caps.

Foam surround replacement question
My woofers' (dynau 30w100) surround have rotted. I ordered a new set of foam surround from speakerbits, Australia. I just discovered that they didn't include the new dust caps. Is it ok to replace surrounds without replacing dust caps? Their instruction didn't mentioned anything about dust caps either.
