Anyone know how I can repair this dent to my beloved M60? Our house was burglarized. The speakers were too heavy to steal (unlike my tv, Onkyo receiver, and Yamaha hi-res audio player), but in the process of knocking the speaker over, the ruffians kicked this mid-range cone.

I've only been able to listen to it once so far - not sure yet how much it affects performance (frankly, not sure if it does at all after one listen to Neko Case). But I'd love to fix this. Insurance should cover the repairs.

Appreciate any advice. Been awhile since I've been on the forum but my Axioms are holding up beautifully.
