Martin Logan Expression ESL 13A

Audio is both real, and imagined. There is the fact of the sound. And there is the feeling that the sound arouses within us.
This feeling is the inspiration behind the new Expression ESL 13A. Like the Expressionist masterpieces, this artful presentation of audio is focused solely on intensifying your emotional experience. It’s a virtually transparent audio performance that transports you to a new landscape of the senses.
