The AR58S crossover is the same as the AR91 crossover except without the attentuition switches and resisters. The drivers are definitely the same. The cabinets are different. A google search will find you plenty of information about these excellent speakers. Last November I recaped my AR58S speakers. These two threads by Darren James and myself maybe helpful to you. Also this thread by Briodo may also be of interest.

The 1210037 woofer is the Tonegen version of the 200037 woofer and can be found in the AR Rock Partner speakers.

Those woofers look fantastic. Anxious to learn what you and Roy discussed and observed about your speakers.

The pair in GA may or may not be OK, but the pair in NJ , one has a DCR of 4.2. Nobody is bidding on that pair.

Good things come to those that wait.

I like how the back of the cabinets are covered with veneer. Much like my AR 10pi speakers. Going back to your broken binding post. Have you lifted the cricut board yet to see how they are configured? If the holes are 3/4 in on center maybe these would work for replacements. You could get a couple to see, and if not compatible they could be used on another project. https://www.parts-express.com/parts-express-dual-binding-post-banana-jack-1-red-1-black--090-475

Maybe this thread will help answer your question. I think your Tonegen woofer may have a raised metal lip instead of the masonite ring.

They sure look like real veneer. I agree with Aadams, send those surrounds back. They deserve better.

Jomede. What a great find. Those are some rare birds. I have no experience with this version of 3a’s. Tonegen drivers, printed circuit boards, vinyl oak covered cabinets. Many AR enthusiasts would love to have these. If they were mine I would value them at least thirty times more than what you have in them. Go slow and gather as much information as you can.

A few years ago I got a set from Simply Speakers. They seemed a bit stiff, so I got another set from Rick Cobb. Much more compliant and perfect fit. Have used at least 6 sets by now. Still have the set from Simply Speakers.

I get mine from Rick Cobb whos sells on ebay as looneytune2001 or you can contact him directly at rcobb@tampabay.rr.com

Welcome Mustbrad to the CSP forums. Your AR 38S speakers use the 200040-0 woofers. These are mine. They pop up on the auction site from time to time. You may have to refoam them. Hers a pair I refoamed for my AR48S speakers. Same woofer used in both models. Notice the inter foam lip is glued to the back of the cones. A bit different than other AR 10 in woofers. They are some really great sounding 2 way speakers. Much like the AR18S speaker except for larger enclosures and woofers. The Rat Shack woofers you currently have probably sound pretty good, but to hear them as AR 38S's you will need the 200040-0 woofers. If you are patient enough they will turn up.

If you can't find Crinoline fabric i have used plane old kitchen cheesecloth.

I don't quite understand the 11.3uf value on the 120uf cap. I have used a few Erse PluseX caps and I like them. How do your new caps read? Are they within the + or - 3%. I agree with the phone cameras getting better and better. Happy Valentines Day everyone.

There are reproductions out there. Check with Vintage AR, they may have some.

Did you play with the tweeter level control on the back. Turn it back and forth and see if the tweeter drops out or has static. That may be your problem. Dirty potentiometers are quite common on 2ax’s

Those are some excellent pictures Stephen. That voice coil former is pretty much destroyed. Unless you want to go with a total recone and new voice coil I would look for another woofer.

That looks like some pretty nice specs on your power amp. Once you get your AR3a Improved speakers sorted out thay MCA 20 will make them sing. If it was me I would look for another Tonegen 1210003-2A woofer and maybe replace those tweeters with these. HIVI QR1 https://www.parts-express.com/hivi-q1r-1-1-8-textile-dome-tweeter--297-417 Don't know if they ship to Australia or you can find them locally, but there is much information here about how with the right inductor and capacitor they are a very favorable replacement to the original AR 3/4 in dome tweeter. Good luck on bringing them back online.

No break in the lead wires or short in the voice coil. Cone moves freely so no magnet shift. No sound when wired directly(no crossover) to an amplified signal.. This is a real mystery. I would try a second multimeter maybe. Check that the spyder is connected properly. You may have to remove the mesh screens to check this. What does your Tonegen replacement woofer Ohm out at? There has to be a explanation. Edit: Just a thought. Try to re-floe the solder between the lead wire and the speaker terminal strip. Could be a cold solder joint.

I like using the gasket tape you can get from Parts Express.Some like cutting new gaskets using a circle cutter. You can get thin foam sheets from Michaels . I have re-used original gaskets before, but they have been compressed and may not be a good seal.

I have never seen those AR 9 and AR 15 models. Here are my AR 15 speakers from the Teledyne Acoustic Research period (1967-1989). Since 1989 three different companies have owned the AR brand. Voxx is the current owner and basically makes inexpensive portable bluetooth speakers of which I do own a pair. Would like to find more information on your speakers because they look interesting. With a center channel speaker they may make a nice home theater system. Other companies have also recycled model numbers over the years. I have two Pioneer PL-570 turntables, one from 1977 which I value over $800.00 and one from 1991 I doubt is worth 1/8 that amount.

Powerglide, your attention to detail raises the bar for many of us that have restored these vintage AR speakers. Congratulations on such a excellent restoration. As far as recording artist from down under there is only one that tops my list. Born in Cambridge, Raised in Melbourne, Four time Grammy Award winner and still going strong at 71.

Hey John, do your replacement 200027 lower midranges have four mounting holes or eight? The ones I refoamed that were in my late production 9's have four holes, but the same speaker in my AR 90's have eight. I have also seen lower midranges with seams in the cone like the ones pictured above.

I was in Harbor Freight Tools today to pick up that folding hand truck I didn't get for Christmas. I saw some small dollies on sale for eight dollars each and that lightbulb went on in my mind. When that happens I never know till later if it was a good thing. Well I managed to get one under one of my Nines. My thought being that I am redoing that room and I will need to be moving them around. As if they are not tall enough. I will probably keep them on the dollies and experiment with placement when I get my new components and furniture in place. Will being five inches higher off the floor make much difference? I am sure the new amplification will make a difference.

Hey Edward how about these jewelbabys. I am getting ready to swap out my Adcom separates(GFA555II) currently driving my AR9's with this new Crown XLS 2502 and vintage Yamaha C-70 preamp. Crown is less than 11 lbs. and should put out about 700 watts per channel into 4 ohms. The cool thing is that the Crown is 2 ohm stable and with a easy mod I can run the AR9's that low. Lots to do to get the room ready. The newer amplifiers are lighter and very powerful , but I still love my vintage stuff.
