MartinLogan Masterpiece Series Electrostatic Loudspeakers (Renaissance ESL 15A, Expression ESL 13A, & Impression ESL 11A)
Product Gallery
Product Overview
MartinLogan's Masterpiece series electrostatic loudspeakers feature a hybrid design that combines MartinLogan's signature XStat CLS Transducer with a powerful dual-amplifier section to deliver a coloration-free audio experience.
The Renaissance ESL 15A, Expression ESL 13A and Impression ESL 11A integrate exclusive Anthem Room Correction (ARC) technology. ARC measures low-frequency sound output in your room and intelligently adjust the bass output for optimal natural sound reproduction.
The Curvilinear Line Source (CLS) electrostatic panel enhances high frequency detail. It produces controlled dispersion radiation pattern that minimizes side-wall reflection.
MartinLogan's PoweredForce Forward bass technology produces powerful bass and reduces front-wall bass reflections, giving you more placement flexibility.
