How can I re-condition my speaker cones (mission 707) loudspeakers?
I have a pair of 1989 Mission 707 loud speakers. The large cones have perished around the outside edge and are starting to break up. I think it's soft foam/rubber, (polypropylene?). The more I use the speakers the more the ring disintegrates. I know there are some companies in the USA who do a mail and return repair service, but none of them will take orders from overseas because of the shipping costs for heavy speakers.
Replacement cones are no longer available from Mission, and the alternatives are not the same. I want to keep the original cones if I can because I love the sound of these speakers and they should have many years use left in them.
I am in the UK and would like to hear from anyone who has solved this problem, or knows where I might get the cones re-conditioned.
