speaker repair

I have 25 year old Wilson X-1 Series 1 speakers. The speakers still are great but the rubber on all the speakers are degrading. Does anyone know of a speaker repair facility in the metro NYC area. It would have to be a facility that would either repair the speakers at my house or that would remove all the woofers to be repaired at their facility then returned and remounted. Each Series 1 is about 600 ibs which is why the whole speaker cannot be removed.
Any help is greatly appreciated.
