    AR-3s With Korina veneer!

    When I saw Liangshan Marsh's post I was excited to hear about another example of some Korina venere classic AR's. Those AR2a's Tom pictured are mine. Picked them up from a guy in Dayton exactly three years ago. They have never been on ebay. Two years ago I got some 3a's in April. Last year a set of 12's in April. Maybe these 3's are my April surprise this year. They sure look good, but I tend to agree that they are probably birch. The 2a's have been put back to original dual mids. They are currently boxed up in storage. I have one original grill, still looking for its mate. Anyway I would like to see another Korina venere example out there.

    Ar-3a Capacitor Advice

    Just checked my October 1973 3a's and here are their numbers.

    Ar-3a Capacitor Advice

    Those serial numbers may be right. My 1970 3a's have serial numbers in the 27XXX range. I earlier stated that I was planning on using Dayton polys for the 150uf and 50uf caps. I also have the option of using these matched Mundorf ecaps instead. What do you guys think. Film or bypassed NPE's.

    Ar-3a Capacitor Advice

    The truth be known I really don't have a favorite capacitor. I use them all. Getting ready to use some Jantzen Superior Caps in some 3a's for the 6uf. One 3.3uf and one 2.7uf paralleled. For the 150 and 50 I like to use Dayton polys. I have used two 50's and a hundred, but this time two 75 and one 50 Dayton. There are so many possibilities and opinions that make capacitor discussions confusing at best. I am a diet coke guy, but when flying on a recent trip I settled for a diet pepsi.

    Upcoming AR3a project

    I used a set of four on some AR5's that had been redone 2 years ago with L-pads on the tweeters and Ohmites on the midranges. Like Ra.Ra. stated the build quality is fantastic. My testing with a ohmmeter shows that the range is spot on and smooth. They are a little bit stiffer than the RHS15RE and don't have the flat shaft end, but these differences turned out to be of no consequence . I wish I had opened one up and looked inside, but it is like the old adage "if it's not broke". I have a set of super nice early 3a's to do this summer and I am debating getting another set or using a set of Ohmites I have stashed away. To me (my opinion) L-pads are not appropriate and rebuilt original Aetna-Pollak pots are just asking for future problems. I wish I knew where Captain Fantastic sourced these potentometers. I will give them two thumbs up.

    Upcoming AR3a project

    Not as expensive as the Ohmite RHS15RE potentometers, and they are self contained. No need for a enclosure. I see they are now $5.00 more than when I purchased them last year.

    Vintage AR2a with vinyl finish (year)?

    Hey Robert, you got my curiosity up. I resized your pictures and will post them for members to see.

    Using AR speakers in a home theater?

    With all the streaming services I rarely use the FM in the cars or home theater setup. I do use the FM on my vinyl playing setup. Today I turned it on and noticed it was a hip hop station, not my regular. Then I remembered my 2 1/2 year old grandson was over a couple of day ago.

    Cracked Broken AR3a .75 inch Tweeter Flange

    I recently super glued a broken flange on a AR48S tweeter. I have a non working unit that I could swap flanges with.

    I Have AR-5's

    Before 9's took their place I had 5's stacked on top of some 2ax's. They both are excellent speakers, but where the 5's walk away from the 2ax's is in the dome midranges. Vocals really stand out along with imaging of many instruments. The bass on both are solid.

    What are these speakers exactly?

    Found this information on the Classic and Limited series speakers which were produced between 1992-1994. http://www.aphenos.net/electronics/speakers/klh/all_ar.htm My question is what were the cabinet covered with. Vinyl or Wood?

    Mortite

    The Mortite rope caulk is a great way to seal those old acoustic suspension cabinets. Here is a AR2ax done that way. Here is a AR4x cabinet sealed with the Parts Express caulk strips. To me it makes the restorations on these classic speakers more authentic. For the ADD and later models it's hard to beat the foam gasket tape. I also cut gaskets from foam sheets, but that is much more labor intensive.I recently has a pair of AR11's where someone used Permatex gasket sealer. Wound up damaging the MDF baffle cutouts removing the woofers. Had to resurface the cutouts with epoxy to repair the wood.
  13. Looking for a AR 12 in woofer Part no. 200003-0. I have a non functional one and would like to try my hand in repairing a set. I believe what I am looking for is a A.4 woofer used in the Mk1 version of the AR 11 and 10pi. Also maybe the Norwood AR3a and LST. The woofer is characterized by the black retaining ring instead of the earlier orange ring. They were produced from 1975 to 1977. Here are pictures of the non functional one I already have. Looking for a reusable cone and frame/magnet assembly.

    WTB AR 12 in. 200003-0 non working or working

    This speaker reconing thing is all new to me. I have replaced surrounds on between thirty and forty sets of woofers, so I want to give it a shot. No I don't have a source for authentic style parts. I was just going to order a AR 11 kit from Speaker Exchange. I am pretty sure the cone will be wrong. Probably the voice coil and spider too. Maybe it will just be a learning experience for me. I will post my attempt when completed. We will see where this winds up.

    AR90 compared to AR91?

    Just figure those 90's are going to cost you $800.00 plus gas money. It always worked for me. I had a uncle that gave his wife a outboard motor for a anniversary gift. That didn't go over.

    WTB AR 12 in. 200003-0 non working or working

    Hi Pete. I am pretty sure the non functional woofer I have is what the AR3a restoration guide labels a A.4 woofer. Does yours have the black surround mounting ring? My woofer does not have a parts number but is stamped 561 7536. If this means it was manufactured the 36 week of 1975 it is definitely a A.4. Yours may be the A.5 version manufactured in 1978. They are pretty much the same except the A.5 has a slightly stiffer suspension. I have both AR11 Mk1 and Mk2 examples.This morning I removed one of the woofers from my Mk1's to see it looked like my example, and to my surprise it was a tonegen replacement. There wasn't even a gasket. My Mk2 speakers are the A.5 woofers. Send me a PM if you are interested in parting with your woofer. I am assuming it has the original cone. Thanks Larry in IN

    Picked up some more AR speakers

    I knew I had some of the Parts Express grill guides around here. Just had to find them. My Nines have the sockets in the speaker cabinets and the pegs on the grills. The PE pegs fit the AR sockets perfectly. The PE sockets are a little loose on my grill pegs although they appear to be the same size. I guess it wouldn't mater if all new parts were used. One other thing is my grill badges are just AR and yours say AR9. I wonder which is the earliest version. Building up and reinforcing the water damaged MDF with epoxy may be tedious, but will restore the integrity of the cabinets. Good Luck. Nines are special and when visitors see them they always want to here them.

    Patient In Cardiac Arrest

    Kent: Thanks for confirming that the tweeters are the same. Sort of like the AR3 phenolic dome tweeter also being used on the AR2a and early AR2ax speakers even though the later two are 8 ohm speakers. The KLH 17 and 20 woofers are the same except for their voice coil windings. Upon some further reading it seems that a lot of open Model 17 tweeters are caused by breaks in the tiny voice coil wire leads. If you can cut and pry off the mesh covers you might find something like this.

    Patient In Cardiac Arrest

    Just a couple of questions. Is there a difference between the bright finished tweeters and the black finished tweeters. I have both kinds in different sets of 17's. Second question. Are the tweeters in my Model 20 speakers different because they are 4 ohm speakers?
  20. lARrybody

    Patient In Cardiac Arrest

    You might check that the insulating washers around the binding post are installed properly because it could be grounding out on the metal plate. Definitely check the tweeters with the ohms function of your multimeter. I have seen several 17 tweeters come to life when the caps were replaced. Check your solder joints again, evan the ones at the tweeter terminals. Always look at the simplest things first. You will be successful.
  21. If your Sony is a STR-AV500 that would be a stereo 2 channel receiver. If it is a STR-DH500 it is a 5.1 channel receiver and would have the menu mentioned above. The STR-AV500 used the RMU80 remote which there are several listed currently on the auction site for under $20.00. That is if you can't find yours.
  22. I agree with Aadams that your 2ax speakers appear to be all AR. The tweeters look like what you might find on some AR 11's or 12's. Still 3/4 in domes ,just from a later generation. The woofers look good, the surrounds look like the roll is a little narrow. Good news is that the more desired surrounds are available. I would get a empty paper towel tube and listen to the mid and high drivers while adjusting the potentometers. The potentometers are the week link in the AR2ax chain and corrode and drop out all the time. They can be replaced if not repairable with L-pads or better yet 15 ohm 25 watt rheostats. There is a lot of music reproduction left in your speakers. Oh, by the way welcome to CSP and I can assure you this is the right place with the best knowledgable people willing to help.

    I Have AR-5's

    L-pads were used on the midranges, thus 25 ohm resistance were added. Could of been added internally, but works the same. The woofers will look fine with the dome dust caps IMHO.
  24. lARrybody

    I Have AR-5's

    .One of my sets of AR5's has the early woofers with the dome dust caps. The other set looks exactly like those that sarals has and have the flat dust caps. One thing of note is that the early woofer frames have 8 mounting holes and the later frames have four. This is compared to the early 2ax ceramic magnet foam surround woofers with six mounting holes. The darker painted woofer below was purchased directly from Tom Tyson.

    Simply Speakers also sells a recone kit. You might ask them if they have the spyder available separately. https://www.simplyspeakers.com/acoustic-research-speaker-recone-kit-ar3-ar9-ar11-rk-ar11.html No affiliation with this company.
