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.
