Description from a website. The Acoustic Research AR-5 from 1969 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. 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.
