AR-4x Speaker replacement
Posted 02 October 2002 - 10:04 AM
Does anyone have suggestions on a good speaker repair shop - the internet has a long listing and all claim great results. I checked with one shop in Sacramento (that came highly recommended) but they wouldn't repair tweeter, just the woofer for a good price. I think I can replace the 8" woofer with something at Layne Audio if needed, but keeping the original tweeters are something I'm concerned about right now.
Yes, the woofers DID have the cloth surrounds - no foam.
Thanks. Anthony V

There is no question that the AR-4x was a superb speaker when it was introduced in 1965. It had very complimentary reviews, as did the AR-4 before it. But in May, 1966, Consumer's Union reported on "Low-Cost Loudspeakers," and the comments they made about the AR-4x were, "...And the best of the lot, the AR-4x, handled these upper ranges as well as -- and perhaps even a shade better than -- any other speaker, no matter how big or expensive, ever put through its paces in our laboratory." It received a "check rating," of course, and "Best-Buy" status as well. Remembering that CU has no ax to grind and makes no commercial consideration for any manufacturer, they pretty much "tell it like it is." Many people would argue with CU ratings, but in truth every manufacturer lusts after a high rating from CU's unbiased testers. I don't think any other loudspeaker ever tested by them has ever received a rating like the AR-4x. Naturally, because of these stellar ratings and the remarkably low cost for such outstanding value, the AR-4x was one of the best-selling loudspeakers in the history of audio.
The chance of restoring the original performance of the AR-4x (let alone improving it) by using different drivers and components is a long shot. By far the best idea is to restore the speaker to its original performance with original-type components, as others have said in this thread. You might search around to find some other AR-4x's from which to cannibalize parts since your cabinets are good.
And incidentally, the woofers in the original AR-4x's did not have urethane-foam surrounds (unless they were replaced somewhere along the way with later-model AR-4xa woofers or such), but were cloth surrounds treated with butyl-rubber compound. This was an excellent woofer. The tweeter was a special 2-1/2-inch cone driver AR made to replace the 3-1/2-inch tweeter used in the earlier AR-4 and also as the midrange in the AR-2ax.
Good luck on your project.
