Details & Highlights

Product Highlights

    Powerful is the word that best describes the EM–R, largest of the ElectroMotion in–ceiling speakers from Martin Logan. The beating heart of this in–ceiling directional speaker is a massive 8–inch high–excursion, high–resolution state–of–the–art woofer. Specifically engineered for detailed bass performance, the EM–R capitlizes on its powerful low–end with an accuracy, authority and extension uncommon to traditional in–ceiling loudspeakers.

Details from MartinLogan

    Folded Motion™ Tweeter

    MartinLogan's exquisite Folded Motion tweeter boasts a radiating surface 8–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% less excursion than the 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.

    Installer Friendly

    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. Installers rejoice as the Folded Motion tweeter is mounted at an angle, allowing the entire speaker to rotate to aim sound precisely where you want it.

    Stealthy Grilles

    MartinLogan's new architectural speakers feature ultra–low profile, paintable micro perforated grilles with no visible bezel for an 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.

    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.

    Multi Application Use

    The EM–R is suitable for any application in small to large rooms. Ideal for use in a multi–channel home theater as a surround speaker, in a kitchen as 2–channel stereo speaker, or in a hallway as part of a distributed audio system.
