MArtinLogan Edge

Folded Motion XT tweeter for detailed sound

One reason the Edge sounds so good is MartinLogan's innovative Folded Motion XT tweeter. Instead of a dome or cone, it uses a pleated diaphragm that works similarly to an accordion by "squeezing" air to create sound. Because it requires almost 90% less excursion than the typical 1" dome tweeter, response time is drastically reduced, along with distortion. The diaphragm's increased surface area also provides wide, yet controlled sound dispersion to create a realistic and highly accurate soundstage. Music and movies will sound amazingly detailed, but smooth and effortless, without a trace of harshness.

Heavy-duty construction and premium-quality parts provide years of trouble-free listening enjoyment.

Solid construction for powerful performance

The speaker's powerful, high-definition bass comes courtesy of a pair of 6-1/2" aluminum cone woofers mounted in rigid, cast-aluminum baskets that minimize unwanted resonance. Dual 3-1/2" drivers supply clear, articulate midrange that blends seamlessly with the Folded Motion XT tweeter. A hand-built, audiophile-grade crossover ensures precise driver integration for high-accuracy sound.

Beneath the Edge's low-profile grille, a thick, vibration-resistant MDF baffle helps lock the drivers securely in place. The baffle sports a high-gloss piano black finish that looks so good you might even be tempted to go grille-less to show off your speakers. The baffle, drivers, and crossover are all contained within a solid, die-cast aluminum chassis that provides outstanding strength and durability. A robust mounting-lock system allows quick, trouble-free installation, providing firm coupling of the speaker to the wall.

The Edge makes an outstanding sonic match with MartinLogan's other Stealth Architectural Series speakers, the Axis and Vanquish, as well their bookshelf and floor-standing speakers.

Features

Stealth Series: Stealth Series speakers are designed to disappear visually into the room, and each one has a completely bezel-less, low-profile, paintable grille for the ultimate stealth installation. Martin Logan's in-house design and engineering team also minimized the grille's perforated metal holes to create a more discreet look, without compromising the quality of sound. A magnetic system secures grilles easily into place, reducing the risk of warping or damage during installation. MartinLogan also refined the look underneath the grille for those who want to show off their high-performance in-wall or in-ceiling speakers. The driver complements are held securely in place by a flush mounted 0.75" solid, high-gloss piano black baffle that hides all mounting hardware

Three-Way Driver Design: The Stealth Series Edge utilizes MartinLogan's 1.25" x 2.4" Folded Motion XT tweeter, along with two 3.5" aluminum midrange drivers and two 6.5" aluminum midbass woofer.

  • Folded Motion Tweeter: MartinLogan's exquisite 1.25" x 2.4" Folded Motion XT tweeter, with its large radiating surface, works by moving air perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm "squeezes" air, requiring almost 90% less excursion than a typical 1" dome tweeter. This drastically minimizes distortion while providing lightning-fast transient response. The increased surface area also delivers wide, yet controlled dispersion ensuring a breathtakingly realistic and delicately etched soundstage. The Folded Motion Tweeter rotates
    easily without the need for tools to allow precise sound dispersion either horizontally or vertically and can be performed post-installation.
  • Aluminum Cone Midrange & Midbass Woofers: The MartinLogan Edge speaker employs two 3.5" aluminum cone midrange drivers with rubber surround and stamped steel basket for open, revealing midrange performance; plus two 6.5" aluminum cone midbass woofers with rubber surround and a cast aluminum basket for deep, accurate bass performance. .

Advanced Crossover Network: Key to the MartinLogan Edge speaker's sophisticated sound is an advanced topology Vojtko crossover network. Each crossover is built on top of double-layered, super-thick, black PC boards and constructed with the highest-quality components. Internals including massive air-core coils, thick, high-purity 16-gauge copper wire, and low-distortion polypropylene capacitors ensure that every nuance of the audio signal is preserved.

Rigid Chassis: The MartinLogan Edge in-wall speakers features a gloss piano-black speaker baffle that hides all mounting hardware, a solid one-piece cast aluminum chassis, and a bezel-less magnetic grille. The speaker has a mounting height of 0.25" from the outer wall.

Spring-Post Terminals: The MartinLogan Edge is fitted with a set of spring-post terminals to connect your in-wall speaker wire.

Robust Mounting System: Edge' robust mounting-lock system is coupled with a solid aluminum chassis. 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 chassis and add rigidity to the wall.

Speaker Applications: The MartinLogan Edge in-wall loudspeaker can be used as a center channel, front left/right speaker, surround left/right speaker, or simply in a stereo or multiroom application.

Speaker Placement: The MartinLogan in-wall speaker offers superb imaging and flexible placement in nearly any location. However, for best performance and imaging place speakers equidistant from one another and avoid physical obstructions between the speaker and primary listening position.

Break-In Period: Allow approximately 72 hours of break-in at 90 dB (moderate listening levels) before any critical listening.

Unfortunately the manufacturer doesn't list that spec. You can reach out to MartinLogan Customer Service (M-F) 8 AM to 5 PM CST. 7857490133. [ Kenny  Jan 07, 2017 ]  Staff
Thanks for your question. It is 0.6875" or 11/16". Hope this helps. [ Kenny  Jan 07, 2017 ]  Staff
The MartinLogan Edge in-wall speakers offer exceptional sound quality for just about any home audio application. However to find out if these speakers are the best option to go in your home, I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They can provide more detailed information tailored to your needs. I hope that helps! [ Larry  Sep 12, 2016 ]  Staff
This speaker is not powered. It can be used as a left/right speaker with a stereo or home theater receiver. That will not get you any voice enhancing technology, but can definitely produce better sound than the speakers in a TV. Feel free to call an advisor on 1-800-324-9695 for a personal recommendation.
