  1. >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 would be difficult, but a history of the "Classic Period," from 1954-1974 (or 1980 perhaps) in one part and the Teledyne/International Jensen/Recoton/Voxx period in another part or in a revised edition. The most important part of AR history is the first 25 years or so. Anyway, please reply with your thoughts and ideas, for example: The best title for such a book? The period covered with this book; part of all? The amount of detail to be included in this book? The size of this book, a small book with 150 pp or so, or comprehensive with perhaps 300 pp? The other questions you might have. There are also many people here on this website with detailed knowledge of specific aspects of AR history and technology. Therefore, give me ideas about how you would like to see such a book. —Tom Tyson 06Jun2017
  2. Hello All, I've been collecting/repairing receivers and turntables for a little while, and now moving to speakers I find myself here. I picked up a pair of AR-2ax's and am interested in getting the cabinets in better shape. They don't need to be perfect and am happy with a bit of original character. The finish is currently quite dull and dark. Also I'm no woodworking expert but it looks like these have possibly had a staining attempt. I've looked at other AR's and don't see much of this colour. Attached are pictures of the top, sides, bottom and back. I did a light sand of the bottom with 120 and 220 grit to see what would happen. It is the worst area for scratches as usual. I'm thinking a light sand all around, but then the next step I'm unsure about. I have used the Howard's products (Restor-a-finish, Orange Oil, Feed n Wax) in the past. I also see a number suggesting Watco Danish Oil which I can get. I wouldn't mind the finish a bit lighter as it's quite dark. I also need more lustre. I've sprayed lacquer on turntable plinths but don't think I want to go that route here is possible. Any thoughts are welcome. Thanks, -Steve
  3. C. Victor Campos C. Victor Campos, 84, from Framingham, Massachusetts, an alumnus of Acoustic Research from 1960 until 1963 and again from 1974 until 1979, died on December 11, 2017 after an extended illness. Victor briefly worked at AR's Music Room in New York in 1959 and later worked in customer services and assisted Ed Villchur with the production of the Live-vs.-Recorded series in the early 1960s. In 1963, Victor went to competitor KLH Research and Development Corporation to work in customer service and engineering under Henry Kloss, but he returned to AR in 1974 working with the Advanced Development Division's new speakers. During these years, Victor produced a superb series of FM broadcasts out of Boston, "Adventures in Sound" and "Shop Talk." These broadcasts were done with master tapes without compression, usually challenging a FM listener's high-fidelity equipment; i.e., if you did not possess AR heavyweight loudspeakers in your system, you were likely to sense distortion during playback! These were superb reel-to-reel tapes done on Ampex AG-440 machines and similar high-end transcription recorders. In the mid 1970s, Victor produced the excellent Neil Grover (drums)/AR-10π live-vs.-recorded demonstrations that showed the extremely capable and accurate reproduction of the AR-10π, especially reproducing the bass drum at high levels. This was a very difficult demonstration—in ways more difficult than the Fine Arts or Gustavo Lopez demonstrations—requiring enormous amplifier peak levels of over 800 watts per channel to reproduce the peak acoustic levels. Steve F on this site attended at least one of those demonstrations and can elaborate on the effectiveness of that demonstration. Much of the credit for the success was due to Victor Campos' understanding of amplifiers, loudspeakers and tape recorders, and he was able to produce excellent results during these LvR demonstrations. Before Victor left AR (he was also at Adcom and NAD through the years), he was very instrumental in the development of the AR9 tower loudspeaker. Initially, Victor wanted the AR9 to be a "powered" speaker complete with built-in amplifiers for woofers, midrange and tweeters, but he was not successful in that quest! At times, Victor could go overboard: when the AR-10 was being developed, a problem occurred with hinge on the fold-out solid-walnut access door on the front. It would bind and stick. Victor wanted to quit "experimenting" and simply cut to the chase: add ball bearings to the hinge! Of course, this was much too expensive, and a proper hinge was developed which worked well without problems. His influence was felt! Victor was an intelligent but sometimes impatient person, yet he accomplished a great deal in the years he was at Acoustic Research and KLH. He will be greatly missed! —Tom Tyson 12Dec2017
  4. Here is a photo of the AR Demonstration Room in Grand Central Station in New York around 1970. It was there for years with various AR speakers and electronics and the turntable. It was only for demonstrations, not for sales. It was permanent for a few years in the late 1960s/early 1970s. Does anyone remember this? (This was a frame from a youtube video at 2:33 by Trainluvr called 1969 plan photos about NYC.)
  5. Hello All, My Name is Sudhir and I write from India. I am very happy to have found this forum of great know how and people with expert knowledge of these wonderful speakers. I have owned a few AR's in India. These are quite a rarity in this country and I have been relentlessly searching to get my hands on more of these speakers. I have a AR18J, the TSW210 and the TSW510 (Dads). Of all these the AR18's are my favorite. I bought them from a guy 15 years ago for some 15$. At that point one of the speaker was not working . A quick inspection revealed that one of the lugs had come off at the woofer. These little speakers have been paired with a Rotel RA - 414 for the last 15 years and have been with a friend when I left the country and are back with me now. Now the 18s were not in the best shape when I got them , but have always sounded nice and rounded. The woofer material seemed to have been replaced locally and I have been searching for a replacement original on ebay for a while and nothing seems to turn up. I see a lot of replacements for the B and BX suffix models , but none for the J suffix. The aim is to return the speakers cosmetically to the condition they were when new. I am willing to CNC the box to exact specs and use the old front baffle as I love the typography on them! Recap the speakers Silver internal wire Use new / refurbish connectors on the rear. I know i will not get the original veneer colour, but will substitute with something very close. Here are some pictures of the speakers and the listening setup. I know i have placed the speakers horizontally, but will have them back vertical as soon as I get the stands shortened! Picture 1: How it looks from the front 2: The typography and front baffle 3. Crossover : Everything seems to original 4. The fill seems to have been added at a later stage. See the colour difference? 5. Woofer front 6 , 7 and 8: Rear of woofer (Seems to be original) 9 and 10. Cabinet disintegration as I moved them around for the pictures! 11 and 12. The original foam grilles in a very delicate shape. 13 and 14 . My listening setup! Experts! Waiting for your suggestions!!!!! Thanks and Regards, Sudhir
  6. I have all the drivers and components needed to finish a pair of AR3 speakers if anyone has a pair of empty cabinets or speakers for parts thanks
  7. Hello Friend of Acoustic Research: A documentary filmmaker from New York -- living in the same town as and acquainted with Edgar Villchur -- is making a documentary film on the life of Edgar Villchur. This film producer is Cambiz Khosravi, a well-known documentary producer, and he is well on the way with his project, "Edgar Villchur: The American Inventor." I've helped him quite a bit, and I think the documentary production will be very nice and a great tribute to Edgar Villchur and Acoustic Research. Mr. Khosravi does need any help he can get to cover the cost of the "production stage" of the film, and PBS -- the likely presenter -- will cover the remaining costs. Therefore, Khosravi has set up a funding site: "https://www.facebook.com/plugins/post.php?href=https%3A%2F%2Fwww.facebook.com%2Fcambiz.khosravi%2Fposts%2F10217946219041185&width=500" If you can help in any way, it would be fantastic! --Tom Tyson
  8. Need 3/4" dome for AR 2ax... Thanks!
  9. Quite an "interesting" opinion by someone called Herb Reichert as part of a review of the Harbeth Monitor 30.2 40th Anniversary Edition loudspeaker over at Stereophile. https://www.stereophile.com/content/harbeth-monitor-302-40th-anniversary-edition-loudspeaker "Everything sounds like what it's made of. I'm known for saying that, and to me, it's obvious: box speakers with dome tweeters sound like box speakers with dome tweeters. I can hear their tweeters calling to me when I'm in the next room, making a phone call. I can hear their boxes hissing and groaning even after I turn off the stereo. Many a day, I think Edgar Villchur, inventor of the acoustic-suspension loudspeaker and the dome tweeter, ruined audio, and that audiophiles will never stop denying how artificially colored the sounds of domes and cones in boxes really are." What say you? As far as I'm concerned the guy is a bullsh*t artist.
  10. My first speaker rehab is a pair of AR-5's. I'm on the woofers which I have determined have bad voice coils. Is it reasonable to think this can be repaired or am I at a point where the woofers need replacement? Thanks for your help!
  11. I recently acquired a pair of KLH model 28's. I know they are rare, but are they collectible? They are too much speaker for me, so I'll probably be selling them. Man can they part your hair. I'm just trying to figure out what I got. Thank you for any help. DJ BTW I have AR-5, AR-2ax, AR-4ax, and KLH 17's. I like them all.
  12. 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 good night!" Merry Christmas! --Tom Tyson
  13. I just happened to be in the right place last Thursday and caught a pair of AR 4xa speakers in a moving sale. Once I confirmed they were actually AR 4xa speakers I took the chance and grabbed them untested for 20.00. They are in rough shape and will be a a restoration project for sure. Took them home and did the battery test 1.5 volt to see if we had any action which I did. So hooked them up as the were and to my surprise they worked perfectly. Amazing AR sound. Being the newbie here I now have a lot of questions. 1. Someone has gone and painted them with what looks like flat black spray paint on the cabinets. Anyone have any suggestions or know of any products to remove the paint without damaging the veneer underneath ? Or is careful sanding the only way ? 2. My other concern is, did the AR 4 xa use foam surround woofers or were they another material ? If they were foam someone has used a rubber or plastic coating to cover the foam, or was that the way these speakers were. What is the best way to clean up the surrounds without damaging the cones ? I will pull all the drivers and stuffing and start the woodworking project, and try to clean up the drivers as best as can be done, along with checking the crossover components. Any suggestions or recommendations on any of the above would be a great help, some pictures below as I found them. Thank in advance for any help. Brian
  14. Hi all, This is my first post in this forum,'ve been reading some post...Congratulations for the contributions!! Two years ago bought a pair of AR 2a in very nice status, but I never have heard them well (musical fidelity a100, marantz 1150, NAD 352...)...could you recommend some that work well with it? thx in advance Diego
  15. I have a set in excellent condition with the controller and cables. I am the original owner and they come with the original boxes as well. I would like 500$ for them. They are located in Portland Oregon. They still sound amazing.
  16. hello classic speaker gurus! this is my 1st post, though i've been a member for a while. i am taking a look at my AR 5 crossovers to see if they need updating. i did some research and found carl's schematic (attached), another schematic (looked the same), and some pictures. so i was surprised when i opened up the box and found this: http://albums.phanfare.com/isolated/Dk50KRQL/1/6272416 i expected 3 capacitors: 4uF, 24 uF and 72 uF. instead i only found one object i immediately recognized as a capacitor (i am a novice at this). it is the 4uF cap. so where are the 24 and 72 uF caps? there is a boxlike object with several wires running into it that seems to be sealed with wax? are there capacitors in there? i bought them from an engineer who said he had restored them but i don't think he remembered the details. maybe i can try to contact them. anyways, would love any advice!

  17. Hello All, I would firstly like to thank the members for helping me out with my AR18 rebuild in my previous thread. Now, for my 4th pair of ARs, I have come across a reasonably decent shape AR93EQ with blown tweeters. Now the other 18s which I bought for the woofers have the tweeters lying around. So from a little research I have concluded that the tweeters on the 18 and 93 use the same tweeter. So, it should be a straight fit. I am really interested in the 93s cause I know they will have pretty much the same characteristics of the 18 with additional lower frequency response. The question is how finicky are these speakers about placement. And how do the side firing woofers behave with a stereo rack in between them? Regards, Sudhir
