Mission 700 woofer refoam

Hello,

I was lucky to be given a pair of Mission 700 speakers. The foam surrounds have completely disintegrated and I'd like to refoam them but one of the cones is a bit bent/distorted - please see the photos. Is there anything I can do to straighten the cone or would the new foam straighten it up?

The Monacor SPH-210 is suggested as a replacement but is kind of pricey and I'm not sure it would work with the crossover so I'd like to stick with the originals if possible.

Any advice would be much appreciated!
