  1. I've just finished restoring a pair of AR-3a's and I'm interested to know how people find they get the best sound from them. I've read a few comments here and there on the forum but couldn't find a specific thread on the subject. So, how do you find the AR-3a to sound its best? Against the wall or out in the room? Toed in or parallel? Tipped back slightly or level? I know some people say they should really be on their sides but that's not an option for me at the moment due to the space. I have mine on home made stands, tipped back a
  2. >I also recall having read the same detailed information from Stereophile, and I assume its correctness against what appears to be a sort of revisionist article containing conflated timelines, unattributed premises and boot-strapped conclusions. >I've been wishing & hoping for Tom Tyson's definitive AR history for years...would a GoFundMe effort be in vain? —ar_pro Book: The History of Acoustic Research Any and all suggestions and ideas here would be greatly appreciated! Any thoughts about what you would like to see would be great as well. To do a complete history wo
  3. This wonderful Christmas poem was sent to me several years ago by a great AR friend (who reports here frequently): T'was the night before Christmas And all through the room, 3a's were playing, Their bass tight with no boom. As Nat sang "Chestnuts..." He sounded so near, Those dome drivers Were playing so clear. From high notes to low notes It sounded so good The melody came through Just as it should Now Santa loves music, And his gifts are so right, "AR speakers for all And to all, a
  4. I know of no other loudspeaker that is more beautiful than the AR-3, that is, in my opinion! I sent this pair to the San Francisco Museum for the Dolby-sponsored "History of Audio" display a few years ago. This pair of early 1960's lacquered-mahogany AR-3 speakers, C 78XX, shows the absolute beauty of the AR-3 cabinet, grill and logo placement. Notice that the logos are properly placed on these speakers and the gold thread in the ivory saran grill material (saran is a Dow Chemical PVDC material very similar to nylon) is evident in this early version. The gold thread was discontinued a
  5. Frank, any room in your knitting class? I distinctly remember saying I wasn't going to buy anymore speakers this year ... Picked up a set of AR-3a's with lots of issues today. It was almost two years ago to the day that I was reintroduced to the AR family with the AR-5 Formica project which was supposed to take its final form this year but has been waylaid once again. This is the first pair of AR-3a's I've seen in the area in those two years -- I passed on them the first time, but hey, if there is anything that I learned from Frank it is that, life is short -- art is long. So, since
  6. For many years—perhaps from the very beginning—AR had a difficult time selling their products in typical audio salon showrooms. In fact, from 1954 until around 1974, AR made no attempt to cultivate good dealer relationships. Nevertheless, and despite the lack of dealer success, AR outsold nearly every other speaker manufacturer worldwide for many years without a strong, formal dealer network. How was this possible? AR products traditionally had the highest ratings and best reviews, but a prospective speaker buyer would never know it to visit the typical, small hi-fi showroom where on
  7. I ordered an Ohmite RHS15R Rheostat Wirewound 15 Ohm 25W Switch to repair my AR-2ax speaker...... I ended up being able to repair the original so didn't need to use the Ohmite RHS15R Rheostat. Asking $30- for it with 1st class mail included in the price. danwenzel@comcast.net
  8. In the review of the A-25, there are several mentions of AR products. I guess at the time of this review, AR was the standard against which everything was compared. http://www.stereophile.com/content/dynaco-25-loudspeaker#KOozMceFiJCv3uCu.97 Anyone know whatever happened to the "aperiodic" design? Today most speaker systems are ported, but there are a number of sealed bookshelf systems. Further, some of the best subs around are sealed boxes. I can't remember ever seeing a modern aperiodic system. Regards, Jerry
  9. I was recently walking down 19th St in NYC when I stumbled upon a pair of beautiful AR-3a's on the curb waiting for the garbage men. I couldn't believe it, so I got a cab and loaded them up and took them home. They're in pretty nice condition, and after plugging them in, almost fully working. Unfortunately, one of the speaker's woofers doesn't work. The foam surround looked good, as did the dust cap. There didn't appear to be any air leaks, but it didn't really make any noise except for a very, very faint bass response and a little rattling. I've been trying to diagnose the problem
  10. Looing to potentially sell a pair of AR-3a speakers that my father purchased and stored for the last 40ish years. What is the best way to vaule these speakers? Appreciate any information. Thank you.
  11. Hi All, I want to try dropping an A23 tweeter in for a poorly-performing A19 in an AR-3a. Assuming they are both 4ohms, is there any reason why this should not work conceptually, and if not, could someone talk me through how to make the transition from front-wired to rear-wired with as little alteration/damage to the cab as possible? Many thanks
  12. Just curious if anyone knows who this auction site user is operating out of High Point, NC? Perhaps TomT since some of his copyrighted material was used with credit. These are historically relevant AR-3a speakers.

  13. Here's what they looked like when I got them: None of the regular pickers at the GWO had ever seen them, apparently. So they were sitting around ignored and available when I got there. I didn't recognize them either, but I was intrigued by the heavy weight, and then I started to get it as I looked at the woofer paper. I had seen that distinctive type paper before, on some AR-93s I restored for someone. Then the notion that I'd heard of Heathkit making a speaker with AR drivers bubbled up.... GWO got $10.00 and I got the speakers. Initial testing shows 5 of six drivers functional. One tw
  14. Compelling AR "Hindsight" Questions: Instead of the 3-way AR-5 with its excellent, expensive midrange and tweeter, should AR have made a good 3-way bookshelf unit using the AR-3a 12-inch woofer and an AR-2ax-type midrange and dome tweeter—at the AR-5 price point—to better compete with (or outgun) the Large Advent? It would use the AR-3a-size cabinet, but it would not include the expensive midrange-dome driver or solid-wood grill molding. It would look like a slightly larger AR-2ax box. As we all know, the AR-5 was (except for deep bass) technically superior to the Advent, but it failed in t
  15. The title gives the goal of this project. Here are three midranges: A: B: C: A is my uninjured midrange, B is the patient, a working midrange that came to me naked, as you see. C is a non-functional midrange that tests open, and is the donor. The hope is to make B look and sound like A. The hard part here is getting the parts wanted off of C. They are glued down tight. Further, on the donor unit, the grill is inset from the outer flange. This is different from my OEM units, on which the whole face is flush, and is making things harder. I'm willing to be destructive with the donor unit
  16. Good Day Friends. I am looking for AR3 cabinets in good to restore-able condition. I have all the drivers needed for the ar3a speakers but lacking cabinets. Please do let me know if you have it.
  17. I'm looking to recap a pair of AR-3a's I have. I understand that involves 50 uf and 150 uf caps as well as a smaller ones. Frankly, those larger sizes can really get expensive with the foil and other types of caps. Is it pure heresy to use an eletrolytic NPE cap in the crossover? I realize they don't have the longevity the other caps have, but when the cost is 10% or less of the other options and funds are tight, I'd like to know what the ramifications are? I understand that originally AR used NPE electrolytic caps in some of their speakers. Will it work...for awhile at least? Will the sound
  18. I've just gone through one of my two pairs of AR-3a and am being reacquainted with what very pleasant speakers they are. But ... it is time to let go of some speakers and I'm going to cut down to just one pair of 3a's, selling my favorite pair (they've been displaced by a pair of AR-90s) and keeping the other, less perfect pair to have as a project. Before I list this pair for sale, I'd like to know (about) when they were made. The irony is that I sold them (to my great uncle) when they were brand new, but can't recall just when, although I'm guessing 1973. The serial numbers are 93511 and
  19. After first being in denial, and then just being annoyed, I need to take action. My beloved 3as, which I received in pristine, unmolested condition in 2010, and for which I made the typical fixes, are now getting a little scratchy in the mids. Just one of them, really. It's the pots, methinks. I brushed away all the green residue with a Dremel back in 2010, and they looked quite clean, but something must have changed. Now, in loud passages, I hear scratchiness. It is not apparent in music for strings, but in solo piano music, or music for flute or French horn, I hear it plainly. It almost soun
  20. Probably been done before but...... What are the differences between an AR3 and an AR3a? What I think is the same: Cabinet (Same size?). Midrange. Woofer. If its the cloth surround AlNiCo type. Known Differences: The tweeter. The crossover. On the subjective side: How would you describe the difference in how they sound?
  21. This spring I purchased an unmatched pair of AR-3a speakers. Although they sound great, one of the speakers (early AR-3a) has always sounded a bit louder in its bass region relative to its mate (1976 factory upgrade 3-to-3a). The reason for this difference has both eluded and bugged me. We just discovered that it is caused by uneaqual woofer inductance values. With helpful insight from Tom Tyson and Edgar Villchur, any possible woofer problems were eliminated long ago. New surrounds; no air leaks; clean level controls--all thanks to the craftsman from whom they were obtained. I replaced all th
