Acoustic Research LST

Multi driver loudspeaker system for professional applications.

Description

The AR Laboratory Standard Transducer is designed for those laboratory and commercial applications that require conveniently repeatable, accurately known spectral energy profiles, including one flat profile extending from 30Hz to 20 kHz.

The AR LST uses a 12 inch acoustic suspension woofer, four 1 1/2 inch mid range hemispherical radiators and four 3/4 inch hemispherical tweeters.

The individual speakers are identical with those of the AR-3A system. Crossover frequencies are 575 and 5000Hz.
