ElectrMotion R 崁入式揚聲器
該電動R是優質高性能的吸頂揚聲器，它採用了較大的8英寸鋁低音單元和角度的折疊運動高音單元為終極性能吸頂應用。揚聲器可旋轉瞄準的聲音。
ElectroMotion RHigh-Performance In-Ceiling Speaker The ElectroMotion R is a premium high-performance in-ceiling speaker that uses a larger 8-inch aluminum woofer and angled Folded Motion tweeter for ultimate-performance in-ceiling applications. The speaker is rotatable to aim sound. The Sound of Invisibility
The ElectroMotionR Architectural Series features our award-winning compact Folded MotionR thin film transducer technology, bringing a new standard in acoustical performance to in-wall and in-ceiling applications. Designed for those seeking the world's most articulate and dynamic multi-channel home theater systems, or simply a stealthy 2-channel system, the Architectural Series speakers are voice and timbre matched with one another, as well as the rest of the MartinLogan line of ultra-premium electrostatic and Folded Motion speakers. Folded MotionR Tweeters
Folded Motion Tweeters work 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.
Stealthy Grilles
ElectroMotion architectural speakers feature ultra-low profile, paintable micro perforated grilles with no visible bezel for 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 employs 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.
