In 27 years, most of the world's hi-fi manufacturers have copied our woofers, our tweeters, and just about everything else in our speakers.
Except the sound.
We invented the acoustic suspension woofer, and they copied that. We invented the hemispheric dome tweeter, and they copied that. What they can't copy is the sound whose bass Stereo Review calls "deeper, flatter and cleaner than that of any other we have tested." The sound High Fidelity says "will satisfy the discriminating listener long after others have lost their charm." See your local AR dealer and hear for yourself. Stereo Review on the AR 9, July, 1978. High Fidelity on the AR 28s. July, 1981.
