New from Acoustic Research

The AR-11

Musical accuracy

A new standard of accuracy from Acoustic Research Musical accuracy 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 recently introduced AR-10π , except that the AR-11 does not incorporate a Woofer Environmental Control and the associated crossover components.

The AR-11 is designed for optimum performance when placed against a wall, as on a bookshelf, or slightly away from two room surfaces, as illustrated.

New drivers

The AR-11 uses a substantially improved version of the 12 inch woofer with which Acoustic Research introduced the acoustic suspension principle to home listeners, as well as the dome midrange driver of the AR-3a.

It also uses a newly designed 3/4 inch high range based on the original high-frequency dome radiator introduced by Acoustic Research in 1959. This high-range incorporates new diaphragm materials, voice coil, and construction techniques that have produced significant improvements over earlier versions.

These drivers, in combination with a new crossover network, have resulted in a speaker system with uniformly dispersed flat energy output to the highest audible frequencies. The AR-11 is able to transmit the information from a program source to listeners in most positions in a listening room with an unprecedented degree of accuracy.

Complete specifications of the AR-11 are available on request from Acoustic Research.

As with all AR speakers, the workmanship and performance of the AR-11 are guaranteed for five years.
