What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

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".
