Expression ESL 13A

Product description
A hybrid electrostatic in MartinLogan's flagship Masterpiece line — the curved XStat panel handles midrange and treble while twin 254 mm aluminium woofers run active, driven by two internal 300 W Class-D amps with Anthem Room Correction. The powered, room-corrected bass solves the usual electrostatic weakness; it still needs an external amp for the panel.
