Celestion SL 700 woofer surround replacement

Has anyone had Celestion SL 700 woofer surrounds replaced? The originals are cracking and I really miss listening to them! I have given up on finding new replacements, and want to find a repair shop that will get them to sound as close to original as possible. Recommendations would be greatly appreciated!

I have had the same problem with sl600 surrounds and sl6SI surrounds. I have obtained several types of flexoble polymer ashesive from the hardware store and done some experiments with each one to determine their flexiblity and other properties. Several worked fine, using a fine artists paint brush applying very small quantities to the tears between the two types of surround material. I first tried ordinary latex, which worked fine but looked unsightly.
