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-priced speaker. 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.
