About the EFX
The MartinLogan ElectroMotion EFX is a versatile, ultra-slim on-wall hybrid electrostatic speaker designed for high-performance home theater systems, particularly as surround speakers. It combines an advanced XStat CLS electrostatic transducer with a 6.5-inch fiber cone woofer in a bass-reflex enclosure, housed in a rigid extruded aluminum AirFrame for minimal vibration and maximum precision. Key technologies include vacuum bonding, MicroPerf stat panels, and a Vojtko crossover network with custom components for exceptional clarity, dynamics, and efficiency. The pivoting wall bracket allows easy sound direction, and it complements other MartinLogan electrostatic speakers. While listed on the official site, availability at some retailers suggests it may be phased out.
