I had the opportunity to help my father-in-law repair his RtR G-200 speakers in his basement system.
These were his first pair of speakers. He bought them while he was in college (so they're 30+ years old at least).
Here's what they looked like before this weekend:
The enclosures are actually in pretty nice shape, but as you can see the surrounds have been replaced by duct tape. Our aim was to fix that and get the drivers back to working condition.
Here's mark working on removing glue from the passive radiator
You can see that we took what was left of the rubber surrounds off of the drivers (more like they fell off) and then scraped the glue from the speaker outer edge with a box cutter. We then hit it with some alcohol and glued new surrounds on. We got the surround kits from Parts Express. It came with everything we needed except the alcohol and some simple tools (screw drivers, box cutters, etc).
here's the PR with the new surround drying on.
The glue that came with the surround kit is some seriously sticky stuff. We ended up with it all over our hands and it was a PITA to remove. It dries nice and clear though so you don't even notice it if you make a mistake and smear it on the driver edge (but you should still be careful not to)
When all was said and done, the speakers looked like this:
The whole process took about 3 hours (including glue dry time) and took what was essentially a useless pair of speakers and returned them to a very nice sounding system (especially with the Carver AVR100 powering them)
P.S. Yes those are 2 pair of Blose sitting on top of the RtRs. I tried like crazy to get the old man to throw those things away now that his speakers are working, but he insisted on hooking them up to the 'B' outputs on the reciever.... For whatever reason he likes them
