MartinLogan EFX On-Wall Electrostatic Surround Speakers

• 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.
• 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.

• The dual 4-inch, ultra-slim fiber cone woofers and four 4-inch passive bass radiators, paired with a Folded Motion tweeter create stunning acoustical alchemy all from a thin profile.
• The drivers are held securely in place by a solid, black-anodized brushed aluminum baffle under the grille.

GoldenEar Invisa Series Ceiling Speakers / In Wall Speakers are engineered to deliver superb state-of-the-art sound quality, designed to blend perfectly with their surroundings and virtually disappear. GoldenEar’s Invisa ceiling speakers line-up consists of the Invisa 525, Invisa 600, Invisa 650 and SP 652 StereoPoint™ Single-point Stereo speaker. GoldenEar’s Invisa high-performance music and home theater models consist of the Home Theater Reference (HTR) 7000, the Invisa MultiPolar™ (MPX) and the Invisa Signature Point Source (SPS). All models incorporate a magnetically attached grill-covered/hidden flange construction that helps to make them virtually invisible. A tremendous amount of work has gone into the acoustical engineering of the Invisa Series Ceiling Speakers / In Wall Speakers in order to deliver the highest sound quality possible in an architectural format. All models (except the 600) incorporate a High Velocity Folded Ribbon (HVFR™) high-frequency radiator similar to the unit used in all of GoldenEar’s award-winning Towers, Bookshelf and Satellite speakers. The Invisa 525 and Invisa 600/650/652 utilize a one-piece driver/frame/flange construction in order to minimize their footprint. Solidly constructed of a marble-infused polymer, the unitized structure actually has the high-definition wide-dispersion driver constructed as an integral part. The Invisa HTR 7000 incorporates our Focus-Field™ Technology with a cast-basket 7" bass/midrange driver and HVFR™ tweeter that are angled under the grille for optimum performance as Main and/or Surround, Rear and Height speakers in a high-quality in-ceiling home theater and music system. The Invisa MPX, with its advanced spaciousness and dispersion, is perfect for in-wall Main or Surround use. The Invisa SPS in-wall SuperSpeaker™ is the perfect anchor for a high-end music and/or home theater system, utilizing GoldenEar’s latest Triton Reference speaker technology. All ceiling speakers/in-wall models have complex multi-element crossovers to precisely blend the drivers for seamless, exquisitely natural sound quality.

Every GoldenEar SuperSat satellite speaker model takes advantage of the extraordinary GoldenEar High‐Velocity Folded Ribbon (HVFR™) design tweeter. The HVFR tweeter propagates sound waves and moves the air by squeezing it with its accordion‐like pleated diaphragm, rather than pushing it as conventional drivers do. The result is better impedance matching to the air in the room with greater control, smoother more extended response with lower distortion and dramatically improved dynamic range. Each SuperSat speaker model also utilizes GoldenEar’s ground‐breaking 4.5" cast-basket upper bass/midrange drivers, which incorporate our proprietary Multi-Vaned Phase Plug design (MVPP™) as well as our proprietary computer optimized cone topology, arranged in a D’Appolito array surrounding the HVFR tweeter.

• Four 4-1/2" high-definition cast-basket MVPP™ bass/midrange drivers
• Two 4" x 7" quadratic planar low-frequency radiators
• One high-velocity folded ribbon (HVFR™) tweeter
