Speaker repair...is it easy?

Thank you.

My concern was I've read something years ago that said if you don't get the glue just right the piston action of the cone would be compromised.

That kind of stuck with me for some reason.

Cheers, and stay safe.

Thanks, everyone.  

I think I will send the driver to a professional for repair since I'm not sure I can even get a replacement speaker for the Dunlavys should I screw the pooch on this repair attempt.

The next logical question:  Who should I send it to?

Thanks.
