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-2a


 The Acoustic Research AR 2a 3-way system loudspeaker
Two 5" Cone units for Sparkling Midrange
Hemispherical Super-Tweeter
Thunderous  "Lows"
Glittering "Highs"
Acoustic Suspension, The concept which expanded the horizons of high fidelity by creating new standards of bass response and low harmonic distortion, is utilized in this moderately-prieced 4-speaker system. The 10" woofer is essentially flat to 42 cps (-10 dB at 30 cps). Harmonic distortion at 40 cps is a mere 3%. Two 5" cone units in dispersed array range from 2000 to 7500 cps. The unique AR Super-Tweeter raises the response beyond 20,000 cps. This hemispherical radiator is without rival for smoothness, low dispersion characteristics and virtually flawless transient response. As a result, the AR2a has received accolades and applause from audio experts and won renown for setting new standards of excellence in its field. The size of theenclosure is dictated by Acoustic Suspension; the air-sealed cabinet providing  a pneumatic spring for most of the cone-restoring force, rather than convential mechanical springing.
Midrange and HF units independently adjustable.
