This why they set the standard for many years.
What work have you done on them?
I have done some soldering on the front terminals for the midrange and tweeter. The pots need to come apart and be cleaned. I'm able to set them the way I like a so i haven't opened the cabinet yet. I just run them as they are they play amazing. Someday I'll pull the woofer and clean, recap the crossover. They sound amazing just as they are.

Wonderful, what kind of amp are you running?
Im running them with a Mc 7270 power amp plenty of power. Clean power is the key.

I'm smitten with My Ar3 speekers. I upped my streeming to Qobuz and it has been worth it. The more detail I put in the more these speakers impress. Classical, jazz, rock. Country. Nothing seems beyond there scope they even put Slayer in perspective. The vocal details are fantastic. I run them at a fairly loud volume and they just sing. I will not be parting with these speakers.

Massive save i was about to pull my midrange and tweeter and just for the heck of it I resolderd all the little connections on the front of the cabinet a Bingo!!! Fixxed!!! Now I don't have to sweet shipping the hard to find midrange. My advice do some soldering irrespective of how things look first. These babies are singing.

The woofer surround Masonite ring was partially loose from the basket. I removed the entire ring from the basket and reattached it with house hold goop. Both surrounds were dry and covered with dried dope particulates. I took a soft paint brush and a vacuum and gently cleaned the surrounds and drivers and then gave them a coat of vintage Ar dope I got on ebay woofers pass the three finger test and sound much better they would just pop out when pushed in. So woofers are good. One speeker has intermittent midrange cut out. I think maybe a bad connection. Maybe a driver issue 🤔. It pops on when I turn the volume up. I don't think its the pot. I'm going to crack it open and see if it's a bad connection or the driver.

I got the 3s as for is the 3a better hard to say.I personally wanted Villchur's design. I also wanted a cloth surround alinco woofer.
-
Thanks, good to know.
-
Will these pots work in a Ar3 as well?
-
The speekers on to are Ar4x. I see in every brochure they show Ar3 Horizontal and my record cabinets put the speakers at ear level when sitting on the couch. I would have liked to meet Villchur and thank him for his acustic suspension invention.

First these are not restored near as I can tell the grills have not been completly off and the pots are the pitts.
After a bit of exercising the pots they came back enough to set mids and tweeters.
The sound is pretty amazing there is a lot of subtle details that my Ar2ax pre1970 miss. And the deep bass is welcome no sub woofer necessary. I'm pleased with the sound and thankfull the midrange domesare working good. I'm going to look for a fabric stretcher and see if I can straighten out the grills. And clean or replace the pots. For now I'm just enjoying them.
Unfortunately someone removed all the rear labels so who knows what vintage these are. When I pull the woofer ill at least know the year.

3s are expensive no doubt. Japanese are tripping over each other for classic Americana. My great uncle had a pair and they had this sound. He ran them with 60rms mono block amps.
-
Sweet, I listen to jazz, rock, classical, I like some of the space age Batchelor pad stuff too. Opra should sound fantastic My 2ax speekers deliver voice like few others I've heard.
-
I will be driving them with a MC7270. I have been running my Pioneer SX1980 lately and really like the phone stage so probably run them with the pioneer for a while it has plenty of power to run the 3s.
-
Vary much looking forward to adding AR3 to my collection i have AR4X, AR2AX as well. I'm listening to the AR2AX at the moment thinking about the 3s. These present well in the photos grills are fair compared to some I've seen. Hopefully the seller will be available today I'd like to collect my new toys.

I was thinking of using that apoxy thanks for the marker link. There are some lesser bumps in less obvious places I will start with them and get a technique going.
25 minutes ago, genek said:Ideally, the best repair would be to cut in a new piece of veneer, but that is probably beyond most hobbyists.
For a filler-based corner rebuild on an otherwise good condition cabinet, I would use an epoxy stick filler in a shade slightly lighter than the surrounding wood (Famowood is great for filling gaps anywhere except right at the point of a corner). With care, it's possible to shape the filler with cards and a blade while it's partially cured and avoid sanding. Then use touch up markers to match the color and recreate grain.
Kent's post has the link to my preferred epoxy filler sticks. Here's a link to the markers I use:

I think I can do it. I just have minimize getting into the undamaged area. And the match the finish with stain. Is the opoxy more durable?
10 minutes ago, JKent said:After applying the filler let it cure thoroughly--overnight is best for WoodWeld, a couple of hours for the epoxy stick or Famowood. Then use a file or sanding block to shape the corner.

Thanks I will look into both. Experiment on something else and get a feel for applying.
-
Nice except for the corner.

Not sure what would help this.

I recently purchased a set ar2ax speakers during shipping I think one corn was damaged not a huge gouge but enough. I am wandering if there is a way to improve the appearance with out getting to invasive? Lucky it is the left rear corner.

Putty is the reason there are so many warped and cracked AR tweeter flanges. AR went to foam gaskets by the mid 70's.

Sure did my ar4x I think they are 71 or 72 vintage they have the black ribbed 8" woofer. have white foam gaskets I had to replace a woofer in one and I just reused the gasket.

Amplifier clipping is I feel the biggest problem with popping these tweeters and or killing any speaker for that matter. I have a 270 watt Mcintosh amp running my Ar2ax. It is a speeker friendly amp it takes a lot to clip this amp.Push them with a lower power/quality amp and you will risk of clipping the amp and taking out a tweeter. I have not blown a speeker with this amp. I don't recommend running a low power amp with these speekers.
-
I would like to thank all those who have contributed to this post. My problem was simple. One of the tweeter wires worked it's way out of the brass spring loaded conector under the tweeter. I just reconnected it and bingo tweeter is alive and well. I am really enjoying the heck out of these speakers.
Ar3 restoration complete
in Acoustic Research
Posted
I just finished my ar3 restoration. All new capacitors and midrange drivers rebuilt. I also replaced all the pots with good originals. All components and midrange repair provided by Roy C.
These speakers sounded vary nice before the restoration however the midrange speakers where not play at the same level the white goo was rock hard on one for sure. Now after Roy's handy work these speakers sound great they have more sparkle and the stage is much more 3 dimensional and voices are smoother and more natural. These speakers are going to be my mains for as long as my ears work. Are there better modern speakers definitely, however how many of them can draw you in and keep you enthralled all day. A3 is a charming speeker no wonder why it was #1.
If you run across a set of unmolested Ar3s definitely send the mids out to Roy C worth every penny. Anyway thats my 2 cents on Ar3 speakers.
