  1. Hi As suggested I am reposting my original inquiry..Where I have already received encouraging feedback. .... have inherited a pair of AR-4x that have been in the family for years and I am interested in rebuilding. I am a total speaker neophyte. They sound a bit flat, that is, not much sparkle or depth and when the volume is turned way up on my 110 Watt/channel receiver they do distort. Is it a given that I must change the tweeter and woofer? Attaching photos. Both speakers woofer and tweeter seems to be in the same condition. Thanks for any advice. ... I
  2. 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
  3. I was browsing the 2016 LIS (loudspeaker industry sourcebook) that came in today's mail reading an article on ferrofluid written by insiders. Discussion went to the use of ferrofluid for coil centering ... "All the way back in the early 1970's, AR discovered that the spider could be removed and ferrofluid used for centering in single-point suspension designs (e.g., the the AR-4x cone tweeter). I've never had one of these apart but wasn't under the impression that the 4x tweeter used ferrofluid... anyone? Reference photo: Roger
  4. This orphan came in today so I recapped it and sealed the massive air leaks around the substitute tweeter. Sounds great paired with the Elwyn 4x although it is a lot brighter/forward in the midrange which is easily adjusted with the pot. Hmmm, guess I'll have to stack it with the orphan AR-338 and see how it does. Serial number 45K in unfinished pine and OSB baffle and back. The back had swelled quite a bit from moisture but the seams are pretty much intact. The cab may actually cleanup fairly well with some effort. Looks like the tweeter may be from KLH. The only marking is M-12 with a late 6
  5. Here is some progress on the previously rumoured "silk-purse" AR-4x's. These were sailboat speakers and ready for the dumpster -- cabs delaminating, etc. I decided to put some of my sailboat experience to work after a friend gave me some black walnut and do a small tribute to the New England craftsmen of old. Serial numbers are 41K+ and crossovers were the early two cap type. You need lot's of free time to do this kind of work, especially with a limited tool set. Sanding is no where near complete but I was testing finishes this morning and got carried away. Roger
  6. These heavily water damaged AR-4x's cleared the auction site this morning for over $170. Serial number unknown. Can anyone explain that to me. The seller thought the woofers were not original but I think we covered this recently. They appear to be dated 1968 which I always remember as the year of the "Tet offensive" -- the fulcrum point of the Vietnam War. Back to the topic, here are some photos. Roger
  7. I have a pair of AR speakers that I bought from a previous owner sometime in the early or mid 1970s and used happily as my main stereo speakers for decades. For the last several years they have been out of service, replaced by a pair of JBL L80T's that I bought more than 15 years ago. About a year ago, I hooked up the ARs for the first time in quite a while and discovered that the tweeter on one of them had blown (or so I thought). I ordered an original replacement from Vintage-AR, but I didn't have a pressing need to use the speakers, so I didn't get around to installing it. Then, a few weeks
  8. Rebuilding some old AR-4x speakers and found a wad of caulking/putty wrapped around the wire bails that hold the Aetna-Pollak pots together. It looks like the same black caulking that was used to seat the speakers to the box. Does anybody know what this is for? Are there vibration/rattling issues with these speakers? I have not seen this caulking on the bails of my other AR speakers but they are not the same model. Should I put caulking on the bails when I'm reassembling these speakers?
  9. I bought a pair of AR-4x speakers that had a newer tweeter in one cabinet, and corroded pots on both, so I decided to rework the pair. I utilized new phenolic ring tweeters - 8 Ohm (http://www.parts-exp...tnumber=270-252), new solen 20uF 400V polypropylene capacitors (http://www.parts-exp...tnumber=027-582) and new L-Pad attenuators - 15W Mono 3/8" Shaft 8 Ohm (http://www.parts-exp...tnumber=260-248) in place of the corroded pots. While the high end is now very well defined, I'm missing the bass that made the speaker sound so full and smooth before I started working on it - overall the sound i
