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.
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.
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.
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.
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.
Synonymous with electrostatic speakers, MartinLogan is famous for producing the finest quality electrostatic speakers for the home audio market. There’s something special about a MartinLogan electrostatic speaker that offers an extraordinary and compellingly realistic audio reproduction. This magical sound is created by using an electrostatic panel with super lightweight diaphragm for instantaneous movement and pairing this with a conventional cone speaker to deliver high quality bass in a hybrid speaker package.
Formed in the late 1970’s by Gayle Martin Sanders and Ron Logan Sutherland, the company created a name for itself in 1983 with the much acclaimed Monolith electrostatic speaker. The company has continued to evolve and develop their technology and now offers a full range of home audio speaker systems for Hi-Fi and Home Cinema systems.
Those who have never heard an electrostatic speaker before will immediately notice the difference when listening to their first MartinLogan electrostatic. View our range of MartinLogan speakers below and get in touch with our team if you need further information.
