Acoustic Research AR2ax Repair Part 1
Vložit
- čas přidán 2. 08. 2018
- Refoam kit was purchased from ebay, there are several sellers that provide parts for Acoustic Research Speakers. I did these videos to help others with repairing their speakers. Its to bad a lot of these awesome old speakers get tossed in the garbage when they're in this condition.
PS This is my first video and have plans for many more. I've been wanting to do this for years but family and work comes first. Hope this video helps some one repair their vintage speakers.
Man, I couldn't get over how exciting it got around the 38 minute mark!!!
Hey if your having trouble sleeping save this video....lol 😉
I had AR5s for years. In spite of upgrades to more esoteric speakers, those were my favourites.
Gave them to my brother, surrounds perished after time.
Lighter fluid works great to remove the glue from the basket edge. I used it in my 1970 2ax restoration about 10 years ago.
I'll keep that in mind the next time I'm working on a set of these.
I found on two AR 2ax in new york about years ago both woofer was in bad so I replace them. I still have them my pioneer elite receiver make them sound great.
The original AR2ax didn't have the cabinet with that kind of front edge, are these some of the last ones in the 60's? Mine where mid 70s
Nice instructions, but I wouldn’t use a speaker cabinet as a worship table.
I wish I knew how to get the grill off. Yes pry it off but to see it done would help
Those speakers are really really good speakers I had a pair wow !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Recently picked up a pair of AR 2Ax speakers at a garage sale, $40.00, nice shape, grill cloth and wood in nice shape. A little Old English scratch cover and they look excellent. Mine are a little later than yours, no screen on woofers, cabinets not routed/stepped in front, tweeter, mid and woofer all working. Was your original foam glued to the back or the front of the speaker? Mine was glued to the back and I ordered new surrounds purposely angled to go under the speaker edge so to glue them to the back. Could be a little more difficult. Need to clean up the reostats, cant wait to try them out.
Why would you work on top of the speaker cabinet?
Is it necessary to send 30 hertz signal to woofer when glueing the outer seal?
Not necessarily. Right after the glue is applied you carefully and evenly push on the cone a bit to make sure the voice coil isn't rubbing. Usually the spider helps keep things lined up but not always. Woofers that are harder to align its better to cut out the dust cap and shim the voice coil while refoaming then just replace the dust cap.
Thanks for the tip. I’m actually reforming the exact same speaker from your video. AR2ax. But I don’t really have a way to send a 30 hertz signal to the woofer while gluing their outer edge.
Original grills were held on with staples and glue. Not Velcro! Someone has already worked on these!
Yes, the original grilles were also beige, i had AR2ax back in the 70's. Surrounds where rubber, ADVENT came out with the foam surround. These have been played with more than once
@@cengeb My AR-2ax are from 1965. They have the treated cloth surrounds. I haven’t had to do anything to the surrounds.

Correct...
I wish i knew to push the cone up while gluing when i repaired an old infinity subwoofer every time i push one side the other would lift up
Now you know, and knowing is half the battle. GI Joe.
Details please. If you are not free to name a brand, what kind of glue and characteristics should I look for? You removed the screens keeping the insulating/sound deadening material away from the cone. AR put screens in for a reason. This does not encourage me to watch this vid. Good initial effort, but sorry, you should re do this.
The glue came with the refoam kit and the bottle doesn't indicate what it is. I've repaired many speakers including others that are sealed acoustic suspension designs just like the AR2ax that are completely stuffed with fiberglass damping. Funny none of them had screens on the woofers.... I guess back in the 60's AR assumed the woofers needed these screens. I've also built a few of my own designs that were similar and never had an issue with the stuffing. I wasn't restoring these to original condition, just repairing so they worked. They're just old AR2ax's nothing super special. They were great back in the day and still pretty good by today's standards but performance wise I wouldn't pay more than $150 for a working set. I can build something better for the money. Now others with a bad case of nostalgia will spend couple hundred on these.
Sorry. Many refoam kits including glue can be found on ebay or partsexpress.com. Sometimes I have to google specific models and buy refoam kits from wherever I can find them.

The screen were designed to keep the loose fiberlass fill from getting in between the cone and the frame, more of a precauation if the fiberglsass started to fly around. Probably wont due to the amount they stuffed in anyway
