Acoustic Research AR-2x

 The AR-2x are lower cost versions of our basic acoustic suspension design. AR-2x has a 10-inch bass speaker, mounted in an acoustically sealed enclosure filled with glass wool, and in addition , a small, high-dispersion cone speaker. Separate controls on the back of the AR-2x  permit independent adjustment of the level of the midrange / high frequency speakers. The performance standard in the design of the AR-2x was the same as that for the AR-3a; natural reproduction of music without exaggeration or artificiality of sound. But where quality in the case of the AR-3a hes been limited only by the state of the art. And our own engineering skill, here price is also a consideration.

 "Clean, balanced and wide range …  from under 50 cycles to beyond audibility this speaker will reproduce what is fed to it with clarity and with honesty …  its strengths lie in an unusual smoothness and lack of any harshness whatsoever."

American Record Guide

"The  bass line is, as we have come to expect from AR, exemplary; well-defined and clean. The highs are quite open … strong fundamental bass to just below 40 Hz … response upward from here is uniform, smooth and remarkably well dispersed all about the speaker".
