Service center for sub woofer

Hello, in the process of making some changes to placement and other things, I just noticed the woofer surround is deteriorating on my Velodyne ULD15 sub woofer. Anyone know of a REPUTABLE service center that can take on this job in the Hudson Valley region of NY, northern NJ or even western CT? I know this is a dated speaker but I've had very good luck with it and it stills sounds very good.
