A delicate project: $1300.0000 on the line

I bought a pair of Acoustic Research AR-3a loudspeakers for $280 about seven years ago. They are classic speakers, made in 1968 or so, and designed in part by Audio Hall-of-Famer Henry Kloss. A minty pair commands about $1300 on eBay. Over the years, I've refinished the wood, had the problematic midrange and tweeter controls repaired in compensation for some wood refinishing work, and made screens for the speakers that match the originals. But I recently heard some distortion on bass note in one speaker, and discovered that the "surround" of the woofer on that speaker has separated from the metal frame that supports it. I am about to embark on a major project: I am going to glue the surround back to the metal frame. I am going to use Gorilla Glue, a powerful adhesive. If I fail, I will have a pair of AR-3as in need of an expensive early woofer. If I succeed, I will have a pair of minty AR-3as worth $1300. I will still have to listen and decide whether I want to sell these speakers or keep them as part of my permanent collection. A single of an earlier version of this speaker is actually in the Smithsonian Institution. Please take a deep breath with me and wish me luck.

Thanks! I just went ahead and put the glue in. The surround is weighted down with a few stain cans. I'm off to see a kid client. It should be dry enough to test when I get back.

@Corbin5 I'll provide a report when I test them. The speakers are great cosmetically, I just want them to work 100% before I decide whether to keep or sell them.

@thislittlepennyearns It looks fine. And sounded fine at low volume last night. I'll try them louder later today.

The speakers from 1968 were made better, than ones we might buy today. I'll definitely wish you luck, that the Gorilla Glue will hold the surrounds back to the metal frame. I can't wait to see them, once you're finished!:)

You are so right! It is worth it to restore these older speakers.

@kobesbuddy I think I have a picture (somewhere on my computer) of what they look like. But they have to sound perfect for me to be happy with them. I want them to be "plug and play," whether I keep them or sell them.

At $1300 I know I would sell them. You can buy another pair to repair and make as good as those ones.

If they sound good enough, I might keep them. These speakers are known for their deep bass, and for sounding good on classical music.

@TheHorse The old speakers were a lot better on classical music, we also have speakers that were built in the 60's.

@LadyDuck They have that warmth that's necessary to convey what it's like to be in a concert hall. Today, I think I will start oiling the pair of Dynaco A-40 XLs I'm working on. Let me see if I can find an old photo that conveys why I enjoy oiling so much. Dry walnut wood looks light. But when you apply the oil, it becomes dark and lovely.

Good luck with the project. This is one you might want to keep the child laborer away from.

I don't think he's helped me with this one. So far, it sounds like the fix worked.

So far so good. I listened at low volume last night. Will really test it (them) later today.

Deep breath taken and good luck wished. Hope it goes well and that Gorilla Glue is well-named.

So, how did it come out, pony? I'm sure you did a good job, though.
