  1. ew tweeter with faceplate removed and terminals at 7 o clock position. Screw holes match up for the original TSW faceplate.
  2. @VinylChef Apologies, wasn't checking the form for a couple of months! Unfortunately the coil which goes around the dome seems to have gone bust (no continuity). But the tweeter is very easy to disassemble and probably a good time to refresh the ferrofluid in there? Once disassembled it is very easy to take a small curved surface and push it from behind. So I decided to take the plunge and buy the Acoustic Research 1210127-1 3/4" Mylar Dome Tweeter from parts express as the mounting seems to be similar. They have finally arrived in India and although I haven't heard them yet , my father says they sound absolutely the same and the harshness is completely gone. He tested with one original and one of these mylar on each speaker in mono. They fit in perfectly with zero modification required. https://www.parts-express.com/AR-1210127-1-3-4-Mylar-Dome-Tweeter-299-2038 There are two more pieces left so if you hurry you can get them! and at 50$ you can't go wrong. There is another version but this seems to shielded. https://www.parts-express.com/Acoustic-Research-1210142-OA-3-4-Fabric-Dome-Tweeter-299-2034 Regards, Sudhir
  3. https://www.ebay.com/itm/ORIGINAL-TSW-710-TWEETER-AND-CROSSOVER-TWEETER-ALSO-FOR-OTHER-TSW-MODELS/163520668898?hash=item26129764e2:g:0lUAAOSwiIxZ94rn The later ones which say "Nitrogen fired" have a golden sheen to them. Wonder if the difference is only cosmetic and durability. Have messaged the seller to see if he can help me out with two of these or one plain aluminium tweeter. Will wait for his reply. Meanwhile, https://www.parts-express.com/acoustic-research-1210127-1-3-4-mylar-dome-tweeter--299-2038 Down in the Q&A a user had adapted them to his 510's. Worth a try?
  4. https://www.ebay.com/itm/ACOUSTIC-RESEARCH-AR-HOLOGRAPHIC-IMAGING-M-1-M2-M4-REPLACEMENT-TWEETER/264973429575?epid=18038929000&hash=item3db1a5ab47:g:FZEAAOSwACpf09-0 Would this be a good substitute? Seems to have mounting screws from the front! and the seller has a pair!
  5. @DavidR Thank you for the headsup! However the tweeter seems to be slightly different. The terminal cutout on my speaker cabinet is at a 7 o clock position while this one seems to be at the bottom. My tweeter has a different mount plate design with screws holding them from the front.This one does not. Probably I can use the diaphragm plate from the ebay one and assemble it in my housing. At 20$ I think I will risk it!
  6. 1210090-0B is the part number. Need one, but if you have a pair, Im willing to pick it up!
  7. Thank you. Will hunt on ebay now! Im attaching a few pictures anyway. Someone might want them in the future!
  8. Hello all, Dads TSW 510s has a blown tweeter. No sound and shows no continuity. Rest of the speakers are all fine. The speakers haven't been pushed or driven at loud volumes. I am guessing it is an age related issue. Are these repairable? I see that all TSW's from the 110 to the 910 use the same part # 1210090-0B. Is there a good substitute for this? The focus plate has three screws from the front holding the tweeters as opposed to the later versions where the tweeter was screwed in from the rear. If anyone has spare, id be happy to buy and retain the original-nes!
  9. Hello all, Over the last few months I have been noticing that my left speaker has been becoming dull. Initially blaming it on room acoustics and my ears, Ive decided to investigate the issue. It turns out that the left tweeter is "seized " and has very little movement compared to the other one. So I pulled out my spare tweeters(older) and discovered that one of them exhibits the same difference in movement. So I have used the "good ones" from the pair and used them for now. But I still hear a mild difference. As in the image sort of shift to the better tweeter especially in recording with female voices. Also the silver outer of the tweeter now don't match and the paper colour is slightly different and this is driving me nuts! So I want to go ahead and do an all out restoration on both the pair. What would you advice me to do? Turn it in to a professional ? Or try the DIY method? If there is professional who can do a great job on this, I don't mind shipping them to the US or UK (I'm from India). Theses speakers are very dear to me and hold a lot of sentimental value. So I don't mind spending some monies on them! Any pointer to the professional who can do this or a DIY kit would be highly appreciated ! Many Thanks, Sudhir
  10. Good day All! After a long silence I am back to playing with my speakers again. Background: I had a pair of not so good AR18s and bought another pair just for the drivers. The spare tweeters bought in a new life to my boxes. The old woofer had butchered voice coils and woofer material, so I swapped them too and now it sounds all pleasant. Why did I not just use the second speaker box? Well the front baffle on the donor was all patchy and mine was mint. I also upgraded my Rotel RA-414 to a Pioneer A-676 and wow! I am a super happy man! The Rotel now pair with the Minimus 7 in my home office. Now I am sitting on a pair of old tweeters and woofers and was wondering how I could put them to good use. 1. I have a AR93 with shot tweeters and would like to use these tweeters on them. How do I get around to refurbishing them? I believe there is an expert on this forum who services them. I wouldn't mind having someone hand carry them to the USA and have it shipped locally to him. 2.The woofer: I have never repaired a woofer ever, but I am confident I will be able to do a mechanically correct job( if not cosmetically). But what do I do with the woofers? Make an opposing box (like the AR93s bottom end) and make a small sub-woofer unit? I know this requires lot of calculations and probably is not worth it as the woofer may not go very low in a sealed box. The other option is to make a cabinet larger than the AR18 ( 17/25/28) and use an exotic tweeter like an AMT to make a hybrid? 3.Use the woofers in the lower cabinet in the configuration they are in now (see pic), seal the tweeter opening and make a (some kind of) hybrid AR94? If I ditch the cabinets, I would like to get rid of the rear switch , binding posts and logos (basically whatever is salvageable) and give it to who ever need them for free on this forum. I have friends travelling almost every alternate month and can do a local courier in the US. I would rather they go to someone who has some use for them instead of hoarding them. Regards, Sudhir
  11. Thanks Giorgio! Will be heading to my parents place in a week! will measure and post results here!!
  12. Thank you! Any idea how much the #200001-1 should measure?
  13. Thanks Gentlemen! Now what should the resistance of the individual drivers be? I want to make sure no one has messed with the voice coils!
  14. @DavidR thanks for the reply. I have a pair of AR18 tweeters . I will replace the tweeters with along with a 4uF capacitors. The resistors too will be changed. Im only worried about the effect the surrounds might have. Who ever did it seemed to have done a good job. But do the dust caps look authentic?
