'dimple' tweeter fix

Hi.I have kept my Dynaudio audience 52SE in a box for a while now. Reason, was my then 2 y.o son was beginning to be inquisitive and he poked the tweeter, hence I have BOTH tweeter with 'dimple'. I've been using my KESTREL's and kinda miss the clarity and dynamic of the 52SE..

So, anyone has an idea how to do it? how much is the parts or where can I buy them (for cheaper than dealer)? any vid around if someone already did this?

.. its an esotar 2 tweeter IIRC

Thanks
