Slim, On-Wall True Hybrid Electrostatic
MartinLogan's EFX is a slim, on-wall hybrid electrostatic loudspeaker. This innovative speaker features XStat™ technology, dramatically reducing cabinet size yet establishing new standards for efficiency, dynamics and precision. It’s not only perfect for home theater duties, but it is ideally suited to surround channel use. The EFX will excel in any role you give it, including front and center channels.
Housed within a radical, ultra-ridgid 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. Complementing the electrostatic panel is a 6.5" high-excursion fiber cone woofer with extended throw drive assembly and bass reflex design for handling the low frequencies.
Slim On-Wall Profile, Pivoting Bracket
If you won't settle for anything but electrostats next to your new flatscreen TV, the EFX is the perfect solution at just 6.5" deep. Free up precious floorspace by mounting EFX to your wall with the included wall brackets. The EFX is also the ultimate high-performance home theater surround speaker and complements MartinLogan's entire line of electrostatic loudspeakers. EFX rotates with the pivoting wall bracket to easily focus your surround sound experience.
CLS XStat Transducer
One of MartinLogan's original breakthroughs, CLS (Curvilinear Line Source) technology, has been an essential ingredient of every electrostatic loudspeaker the company has ever produced, and the EFX is no exception. Proprietary manufacturing methods enable construction of electrostatic panels as cylindrical sections. Their gentle horizontal curvature solves the problem of obtaining good high-frequency dispersion from a large radiating surface without compromising overall sound quality or reliability.
Advanced Vojtko Filtering
Proprietary Vojtko filtering technology is utilized for EFX's electrostatic transducer. This audiophile-quality network, derived from the premium CLX speaker, is carefully hand-built using precision point-to-point wiring, polypropylene capacitors, massive air-core coils, and a custom wound E-I core transformer. It flawlessly preserves micro-acoustic subtleties while effortlessly handling the broadest range of dynamics contained within even the most demanding sonic source.
Custom Five-Way Binding Posts and Low-Voltage Power Supply
MartinLogan's proprietary tool-less binding posts simplify cable connection and management. EFX features custom five-way binding posts to 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, which eliminates the need for a traditional, heavy IEC power cord.
