Advanced Vojtko Filtering
Proprietary Vojtko filtering technology is utilized for EFX's electrostatic transducer. This audiophile quality network, derived from the CLX, is carefully hand-built using precision point-to-point wiring, polypropylene capacitors, massive air-core coils, and a custom wound E-I core transformer—flawlessly preserving micro-acoustic subtleties while effortlessly handling the broadest range of dynamics contained within even the most demanding sonic source.
Custom 5-Way Binding Posts and Low-Voltage Power Supply
MartinLogan's proprietary tool-less binding posts simplify cable connection and management. EFX features custom 5-way binding posts and provide the ultimate level of flexibility for connection and setup. To further simplify setup and cable management, the EFX features a low-voltage DC power supply eliminates the need for a traditional, heavy IEC power cord.
Surround Yourself with EFX
MartinLogan is proud to introduce the slim, on-wall EFX™ hybrid electrostatic loudspeaker, featuring XStat™ technology, dramatically reducing cabinet size, yet establishing new standards for efficiency, dynamics and precision.
CLS™ XStat Transducer
Housed within a radical, ultra-ridged extruded aluminum AirFrame™, the EFX's new CLS XStat transducer builds upon the legacy of MartinLogan's electrostatic heritage with the incorporation of advanced vacuum bonding and MicroPerf stat panels, providing even greater efficiency and precision.
