Description
The EFX is a slim, on-wall hybrid electrostatic loudspeaker built around MartinLogan's XStat CLS transducer, designed as a versatile surround speaker for any MartinLogan home theater system. At just 6.5in deep, it mounts to the wall on a pivoting bracket to free up floor space while delivering the precision and dynamics of MartinLogan's electrostatic heritage.
