The foam surround had deteriorated on the woofers and was replaced in 1998. The repair included new surround, voice coil and cone. It was replaced as an assembly, an upgrade from McIntosh. The work was done by Speaker Repair Service in Fort Worth. They were a McIntosh factory authorized servicer. No, those are not Cerwin Vega drivers, lol.

Also, a high frequency mid was replaced in 1998, a direct replacement from McIntosh.

There is some minor water damage on the replacable (repairable?) base of one of the speakers, a cosmetic issue.

I have scanned the Owner's Manual (2 included), Service Information Lit (2 included), XR Series Dealer Brochure, Service Invoices and reciepts etc. Also included are 33 high res photos of the speakers. You can download a 42MB zip file containing all scans/photos here:
