What on Earth IS this thing?

one AR-2ax along with the tools we used to take it apart

How does a nerdy professor spend his Saturday morning? A friend stopped by without warning. He's a fellow audio geek (and a retired engineer), so we spent the morning tearing apart a pair of Acoustic Research AR-2ax vintage loudspeakers from 1972 or so. I already refinished the dark walnut cabinets. He's going to take the woofers home and fix them. I'm going to remove the nasty fiberglass stuffing and try to fix the midrange and treble controls (called potentiometers, or "pots" for short) that always go bad on older Acoustic Research speakers. I'm also going to make new grille cloths for the speakers. When we're done, we hope to have a fully functional (and very beautiful) pair of AR-2axs from something that might have wound up in the dumpster. They're actually excellent sounding speakers and would be worth about $300 for the pair if we get everything right. I might keep them, though.

When you work on something you get attached to the work and the item in question as well. I would keep things because I'm a pack rat.

@TheHorse I work on other people's stuff all the time, and most of the time it's ideas, so I don't get attached.

@OneOfMany That would be satisfying too. Especially if they ACT on the work you do together.

It IS hard to say goodbye to something I've worked on. But most of what I do is for someone else (fortunately).

I hope the repairs go as well as expected.

Thanks! I'm pretty confident we'll come up with a pair that looks and sounds good. These (AR-2axs) are what my parents had when I was a kid. So they have some sentimental significance.

My husband always wants to keep every car he fixes. I can imagine you wanting to keep these once you repair them.

I can relate. When I own them (I own these), it's hard to part with them. But I manage to sell most of what I own and refinish. I admit, though, that I have about five pairs of speakers already in my "permanent collection." Well, maybe six. Or so. Definitely not more than eight.

Thanks, Judy. We'll give it our best shot.

I am sure you will end up with a beautiful pair of AR-2axs. I agree that in old loudspeakers the potentiometers always went bad.

@TheHorse I have to repair an old radio, a friend gave it to us, as you can see it's not in a very bad shape, except for the ivory buttons.

@LadyDuck Wow--that looks cool! Is it from the 1950s or early 1960s? Will you be restoring both the insides and the outside? Does it have tubes? Tube radios sound the best!

Acoustic Research was one of the best makers of speakers in the "golden era" of hi fi (the 1960s and 1970s). But those dang "pots" were an area where they skimped. They are notorious for going bad.

It surprises me that you are able to find things made of wood to renovate. I thought they would all be replaced by fake stuff by now.

Well, there's mostly fake stuff in the stores. Many of these old speakers have been hidden in someone's garage for years. Many of my "customers" are older guys returning to the stuff of their youth after the kids are grown and gone. But some are "hip" younger couples who are going back to vinyl (records) and quality stereo gear.

I had big speakers like that when I was a teenager.

Do you remember what brand? This was my hobby (reading about all this stuff) back when I was a kid and too young to own what I was reading about. My first "real" speakers were Dynaco A-25s.
