“The MartinLogan Stealth line of architectural speakers impressed me. Their build and component quality is significantly high. It is obvious that much thought went into the design of these speakers, and the results are ultra high-end. MartinLogan has created a quality product that will provide a proud sense of ownership. When coupled with the BalancedForce 210 subwoofer, the sum performance was greater than any one speaker’s individual achievement. I used to avoid my family room… However, thanks to the addition of the Vanquish and Axis speakers, I now find myself wanting to watch movies in the family room. I would highly recommend this product if you are considering an architectural speaker solution for your space” – Greg Handy, Home Theater Review
Folded Motion® XT Tweeters
The signature Folded Motion tweeters utilize extremely low mass diaphragms that “squeeze” air, and require significantly less excursion than the typical 1-inch 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.
The low distortion Folded Motion XT tweeter boasts a radiating surface 40% larger than those found in the award-winning Motion® Series products. This substantial leap in size increases the bandwidth and efficiency of the high-performance tweeter for effortless performance.
Design and Aesthetics
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. Our 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.
We’ve 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 3/4-inch solid, high-gloss piano black baffle that hides all mounting hardware.
Key to their 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.
Quick, Trouble-Free Installation
Critical to architectural products is their ease of installation. The Stealth Series continues MartinLogan’s tradition of innovative engineering solutions which allow custom retailers to quickly and easily install their products. Each model features easy push style inputs and an extremely robust mounting-lock system that couples with the speaker’s rigid aluminum chassis when installed. Axis and Edge in-wall models feature rotatable tweeters, which allows installers complete flexibility for both horizontal or vertical installation. Axis is sized to fit perfectly between standard 16-inch stud spacing for center channel applications.
Vanquish includes two toggle switches to tailor performance for whatever application is intended; either front left, front right, center channel, surround left or surround right.
