Wierd vibration sound coming from speaker cone after replacement. Help appreciated

[Jonathan Sjogren]

After I replaced my sorround foam on a couple of old speakers I started to experience wierd and powerful vibration sounds from my left speaker as soon as a bass heavy song came on at desent volume. This was not there before I replaced which I find very wierd, I tried alot of things but for no avail. Help would be appreciated.

It is super critical when you replace the surround on a speaker that the voice coil be perfectly centered. Not that easy to do with enough precision. If it's not centered your get distortion caused by the voice coil rubbing. You can try it again or get a pro to do the job right.

Hey. Thanks for the tip. Im pretty sure that's not the problem because however I press the cone in whatever position it doesn't rub anything.
