Acoustic Research AR-3a speakers. Speakers are in good working condition. I have used these as my main speakers for the last year and have now replaced them with a new set of speakers. Speakers sound great and are in good working condition. Tweeters are not original and were replaced by original owner at some point. One tweeter does not produce sound and I have never tried to repair as I just bypass tweeters anyway. One speaker is missing the adjustment nobs for increasing or decreasing the mid and hi. Cabinets are in good original condition, some scratches and minor chips in veneer. Lower serial numbers 2506 and 2508. One badge is missing the AR-3a emblem and the other has come apart, a little glue will fix this. Grill cloths are in decent shape with some minor puling at corners.
