Very high quality drivers with good crossover Emit tweeter does a good job with the high end.
Well balanced sound– drivers have rubber surrounds for no foam rot. Sound best on stands with tweeters at ear level.

Owned the same pair since 1979. The only component failures were due to stupidity (driving too hard). Very natural sound. Have to move up to the Infinity tower to go better.
