MartinLogan ElectroMotion IW In Wall Speaker

Powerful In-Wall Speaker

The ElectroMotion EM-IW in-wall speaker features MartinLogan's Folded Motion™ tweeter and a 6.5" aluminum cone woofer with cast aluminum basket that provides powerful low-frequency bass extension.

A robust mounting-lock system allows quick, trouble-free installation. When not in use, the constant-control mounting locks are held securely within a self-contained housing. When moved into place during installation, they couple the speaker’s chassis firmly to the ceiling. And if the speaker is ever removed, the locks retract and latch themselves back in their housings.

Precision-Built,Advanced-Topology Vojtko Crossover

Carefully hand-built using only the finest polyester capacitors and air-core coils, the crossover employ's MartinLogan's proprietary Vojtko™ topology for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.

ElectroMotion Architectural Series Speakers

The ElectroMotion® Architectural Series features MartinLogan's award-winning compact Folded Motion™ thin film transducer technology, bringing a new standard in acoustical performance to in-wall and in-ceiling applications. Designed for audiophiles who are seeking the world's most articulate and dynamic multi-channel home theater systems, or simply a stealthy two-channel system, the Architectural Series speakers are voice and timbre matched with one another, as well as with the rest of the MartinLogan line of ultra-premium electrostatic and Folded Motion speakers.

Folded Motion Tweeter

MartinLogan's exquisite Folded Motion™ tweeter boasts a radiating surface eight-times larger than a typical 1" dome tweeter. The Folded Motion Tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works.

This extremely low mass diaphragm 'squeezes' air and requires almost 90 percent less excursion than a typical 1" dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.

Ultra-Low Profile, Micro Perforated Grille

All models feature an ultra-low profile, micro perforated grille with no visible bezel, which are also paintable for a near invisible integration into any wall or ceiling. A magnetic system secures grilles easily into place, reducing the risk of warping or damage during installation.
