Surround Yourself with EFX

 

Martin Logan's EFX is a hybrid electrostatic loudspeaker, catered for wall-mountability and home-theatre surround sound. This sophisticated speaker utilises XStat technology, which greatly decreases the space taken up by the speaker's cabinet, but also delivers highly impressive efficiency, dynamics and precision. 

CLS™ XStat™ Transducer

Placed within a profound, ultra-ridget extruded aluminium 'AirFrame', the recent CLS XStat transducer builds upon the same concept and philosophy of Martin Logan's electrostatic speaker options, but also incorperates a highly advanced vacuum bonding method and 'MircroPerf' stat panels. This enables the EFX to deliver an even greater and more precise sound than that of its competitors.

Slim On-Wall Profile

The EFX is a perfect match for your flat screen TV, being only 6.5 inces in depth. You are able to make the most of your precious floorspace by mounting the speakers on your wall with the dedicated wall brackets included. The EFX is one of the most sophisticated and glorious sounding home theatre surround sound options available, and compliments Martin Logan's entire range of Electrostatic speakers. The EFX also rotates, thanks to its pivoting wall bracket. This allows you to focus your surround sound experience to directly fit your requirements.

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.
