Need help regarding speaker repair

[tannoy611mkII]

Hi
I am from Kolkata, India.
Recently, I noticed that the foam surround of my tannoy sixes 611 MK II speakers has gone brittle.
I need to get them replaced. Can anyone point me to someone authentic from Kolkata, from where I would be able to get them repaired?
Regards.
