Acoustic Research AR-90
Multiple Driver Reference Loudspeaker System

Description
The Acoustic Research AR-90 are very high precision devices, designed and built to tolerances comparable only to professional studio microphones.
They far exceed the performance capabilities of the classic laboratory reference standard and AR LSTs.
All of the modern technology in speaker design, as well as the most sophisticated of computer techniques, were used, not only in the development, but continually throughout their design and manufacture.
The three most distinctive applications of this technology in the AR-90s are the Acoustic Blanket, the vertical, upper-range driver array, and the positioning of the two woofers, one on each side of the enclosure.
The former two insuring unprecedented imaging and precision of localization and the latter unequalled flat frequency response in any listening environment, particularly at lowest music frequencies.
Indeed, the clarity of the AR-90s will make you aware of limitations in associated equipment, including the finest electronics. As a result, any improvements in the chain preceding the AR-90 will seem to continually improve the overall performance.
