Hi Ash,
The eden recommended repair company is Surrey amps, also called the amp hospital, he did my metro when I blew both cones, he is good but it is a little expensive I would guess its going to cost you £125 plus vat per speaker plus postage. You just pull out the speakers and mail them to him, speak to stan he is a good man.
Or if you go on e bay and look up mikes chop shop he will post you new replacement speakers at probably less than the re cones, I also blew my 210xlt and with vat and post it was going to be £300 ie $500 I got 2 new speakers including postage from the states for $290, mike is a good man as well and does cheap strings.
If you go on the eden web and go to the chat section, ask about the speaker and you will have a model etc within 24 hours, they are good guys on there.
Any problems drop me a mail and I have all the contact details at work.
Rob
