VINTAGE ACOUSTIC RESEARCH AR-11 AR11 LOUDSPEAKERS SPEAKERS (2) BIN. The AR-11 is the most accurate speaker system ever made by Acoustic Research. Its performance, drivers, and crossover are identical to those of the AR-10 except that the AR-11 does not incorporate a Woofer Environmental Control and the associated crossover components. They are 4 ohm speakers. The AR-11 is designed for optimum performance when placed against a wall, as on a bookshelf, or slightly away from two room surfaces. It uses a substantially improved version of the 305 mm (12 in) woofer with which Acoustic Research introduced the acoustic suspension principle to home listeners, as well as the hemispherical dome midrange of the AR-3a. It also uses a newly designed 19 mm (3/4 in) high range based on the original high-frequency dome radiator introduced by Acoustic Research in 1959. This high-range driver incorporates new diaphragm materials, voice coil, and construction techniques that have produced significant improvements in performance over earlier versions. It has a lower resonance frequency and more extended high-frequency response, plus greater efficiency and higher available output. These drivers are used with a new crossover network to produce a speaker system with uniformly dispersed flat energy output to the highest audible frequencies. It is able to transmit the information from a program source to listeners in most locations in a room with an unprecedented degree of accuracy. A pair of three-position switches provide a means of decreasing the overall level of the midrange and high range drivers in 3dB steps. The 0 position of the switches should provide the most accurate results in most listening rooms, while the -3dB and -6dB settings are useful for compensating for the effects of more reverberant, or live rooms.
