These are pretty rare vintage speakers (53 years old) especially in their all original, unmolested condition. Some people prefer these to the bass heavy AR-3’s They are the early model AR-5’s with all original drivers. These are offered at a small fraction of the price of AR-3’s. These are fully tested and working as they should. All original unmolested, unrestored cabinets, grills and badges. Just re-foamed will all new potentiometers. The grills have some fraying from being removed, but still very presentable all original condition. The cabinets are very nice with only a small back corner ding and very nice original condition. Please look carefully at all the pictures for their exact condition. The Acoustic Research AR-5 from 1968 is often named to be one of the greatest vintage speakers available at an affordable cost. The AR-5 is a three way speaker using a 10 woofer, a 1,5 dome midrange and a 0.75 dome tweeter. Currently the price depends strongly on the condition of the speakers. The AR5 features the intricate and well-designed crossover network of the AR3a and a similar midrange driver. Therefore, AR-5s have a detailed mid and high response and at the same time deep bass, less deep than the AR-3, but with more soul than the AR-2ax. According to audio karma’s forum AR5 was meant for those people who thought the AR3a was a little too bass heavy. Its midrange drivers and tweeters were basically the same as the ones of the AR3a, which was clearly superior to the 2ax. The reason for the existence of the AR5 was to give people an alternative between the AR2ax and the AR3a. AR-5 Quotes and Specs. AR´s model manual went more into detail to explain the differences to the AR-3a. The manual states that inside the AR-5 are the two hemispherical dome speakers of the AR-3a, which provide uniquely accurate midrange and high-frequency reproduction, and a completely new 254 mm (10 in) woofer. The main differences between the AR-3a extends approximately 1/3 octave lower, and the price of the AR-5 is less. The AR-5 pioneered several advances in materials technology that help make its performance possible. These advances have subsequently been incorporated into other AR speaker systems. The cone of the woofer, for example, is molded by a low-vacuum process developed for AR, which greatly reduces the tendency to coloration heard in conventional cones of paper or polystyrene. At the cone´s outer edge is a suspension of urethane polymer, which helps to achieve very low distortion at low frequencies. The AR-5, in fact, is one of today´s most advanced speaker systems, the result of combining AR´s years of experience with the newest processes and materials. The AR-5 series are definetily worth to be refoamed. Many of them have foam surrounds that rotted away over the years. It does not require any particular skill, just a calm hand and a little patience. We tried out several different available foams and recommend to use Parts Express´ 10 inch Surround Kit. You can find it in our Store or directly at on the right. Acoustic Research AR-5 Specs.

You must pass all three tests without any damage, cosmetically or functionality. I think it’s worth a few extra bucks, because they can’t be replaced.
