Repaired two woofer cone but one woofer had dustcap bigger then the other due to unavailability of same size will it create any issues ?

You might be able to measure it but it’s not likely to be big deal.

This is the back side of speaker cone, it's some kind of speakers glue will it have some effects on audio.
