sudhir Posted January 11, 2019 Report Share Posted January 11, 2019 I was home for the holidays and dad showed me his latest find. A pair of not so well kept AR94ER . The speaker appear to be intact except for the tweeter which has been replaced along with the capacitor which is now 3.5μF. I have a pair of spare tweeter for a AR18 project and a few 6μF capacitors to start experimenting with. Now I am wondering if the rest of the drivers are intact as I think they are. Please give me your suggestions. 1. Full speaker. Someone decided to give it a go with a silver paint can. 2.Closeup of surround and woofer material. (is this the original?) 3.Middle driver - speaker A 4.Middle driver - inside (surround seems to be stuck from behind, I though it was supposed to be from the front?) 5.Lower driver - speaker A 6.Crossover -speaker A 7.Middle driver - speaker B 8.Lower driver - speaker B 9.Crossover -speaker B 10. Tweeter ( dont know what tweeter this is ) Now if I get the original tweeters for this is it worth the time and money? I can have my neighborhood carpenter sand and spray the cabinets black again. Replace the tweeter and capacitor. But are the woofer and the materials clean enough? The plastic top and bottom are fine and intact. Cloth is reasonably good , but could use a wash. Dad uses a TSW 510 right now. Even though they are a bit bright, they work well with his ears. How do these speakers fair against the TSW. I use AR18s and love them to bits. Would these sound closer to the 18s? Regards, Sudhir Quote Link to comment Share on other sites More sharing options...
DavidR Posted January 11, 2019 Report Share Posted January 11, 2019 The tweeter does not look like an AR tweeter. The 8" drivers are old style AR - must be very early 94's. Usually you find Tonegen drivers. The foam should be attached to the face of the cone not the rear. The tweeter cap should be a 4uF. One resistor looks cooked.

sudhir Posted January 15, 2019 Author Report Share Posted January 15, 2019 @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?

DavidR Posted January 15, 2019 Report Share Posted January 15, 2019 They have a nice big roll on the surrounds. Hard to tell about the dust cap. The type isn't too important IMO. Anything close to original will be fine. I think the originals were just paper. Quote Link to comment Share on other sites More sharing options...
djcheung Posted January 15, 2019 Report Share Posted January 15, 2019 I repaired a pair of 94er sometime ago. The surrounds were indeed on top of the cones and not under. The picture below shows the before image. Quote Link to comment Share on other sites More sharing options...
sudhir Posted January 15, 2019 Author Report Share Posted January 15, 2019 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! Quote Link to comment Share on other sites More sharing options...

Giorgio AR Posted January 16, 2019 Report Share Posted January 16, 2019 Hi Sudhir, I have 4 woofers 200001 and at my multimeter they measure 4.7 and 5.0 ohm as you can see from the photos Quote Link to comment Share on other sites More sharing options...
sudhir Posted January 25, 2019 Author Report Share Posted January 25, 2019 Thanks Giorgio! Will be heading to my parents place in a week! will measure and post results here!! Quote Link to comment Share on other sites More sharing options...
DavidR Posted January 25, 2019 Report Share Posted January 25, 2019 Those readings are correct and good. Quote Link to comment Share on other sites More sharing options...
Listening Posted June 6, 2021 Report Share Posted June 6, 2021 I enjoyed reading this post admiring your expertise. I have a very simple question about these speakers. I inherited the pair of speakers from my father and am very fond of them. However, the space I have available is very limited. Do you think I could place the Yamaha HS8 I use for audio editing and production on top of these speakers, or could I ruin them? They weigh approximately 22.5 lb (10.2 kg) each. Thanks for any feedback! Quote Link to comment Share on other sites More sharing options...
