Martin Logan EFX On-Wall Speaker Black
Get off the floor and on the wall with the EFX electrostatic on-wall speaker. The EFX, MartinLogan’s slimmest reference quality on-wall solution to date, provides loyal electrostatic speaker enthusiasts the flexibility for either surround or front solutions in a slim, space saving package.
CLS XStat Transducer
Housed within a radical, ultra-ridged extruded aluminum AirFrame, the EFX's 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.
Slim On-Wall Profile
If you won't settle for anything but electrostats next to your flatscreen TV, the EFX is the perfect solution at just 6.5-inches 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.
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, eliminating the need for a traditional, heavy IEC power cord.

Martin Logan
Martin Logan is a Canadian/US company producing conventional subwoofer speakers as well as floor-standing, wall-mounted, and in-wall hybrid speakers using electrostatic loudspeaker and planar magnetic thin film loudspeaker technology.In 1989, and again in 1990, Inc. magazine recognized MartinLogan as one of the 500 fastest-growing privately held companies in the United States.The early 1990s saw the rise of home theater with the availability of new multi-channel sources. MartinLogan delivered the world’s first electrostatic center-channel speaker, Logos, and on-wall surround-channel speakers, Stylos. Engineered for instant, accurate response, and matched to the performance levels of existing electrostatic loudspeakers, these utterly new designs established MartinLogan as a major force in home theater.By the mid-aughts, with the development of more advanced technology, MartinLogan personified superior quality and performance in the rarified electrostatic loudspeaker space. This reputation was bolstered by groundbreaking innovations throughout the early decade of the new century. These included the development of MicroPerf ESL stator technology, as well as the first use of non-ESL Advanced Thin Films. This was the seed that would ultimately bloom as Folded Motion tweeter technology.The high-end Summit electrostatic loudspeaker, first introduced in 2005, garnered rave reviews from the professional audio press for both performance and design. It pioneered the use of MartinLogan’s Ultra-Rigid AirFrame, a precision-manufactured panel frame that improved stability, and thus imaging and detail.Today, MartinLogan continues in the tradition of its innovative founders, with hands-on design and engineering, and proprietary manufacturing techniques. Constant improvements on the vanguard of electrostatic and thin film transducer technology keep MartinLogan on the cutting edge of audio innovation.
