About this product
In luxury distributed audio, the challenge is delivering consistent, high-quality bass without the visual clutter of large grilles. The MartinLogan Variable Aperture System (VAS) solves this by delivering high-output, full-range performance through a variety of aperture options that elegantly blend in with recessed lighting. With both full-range speaker and dedicated subwoofer options, the VAS is a highly configurable system able to achieve 38 different looks, including the ability to disguise the subwoofer as a stealthy air vent.
Solving the "Design vs. Performance" Dilemma
Small in-ceiling speakers have traditionally forced a choice between aesthetics and performance. The Variable Aperture System eliminates that compromise with a concealed, high-volume enclosure hidden above the ceiling. The result is the bass, dynamics, and authority of a much larger speaker delivered through an aperture that blends seamlessly with designer LED downlights—creating spaces that look beautiful and sound extraordinary.
The Variable Aperture Speaker
The full-range solution for minimalist spaces, delivering clear, dynamic sound from a discreet opening. A specialized 2" aluminum driver reproduces midrange and high frequencies with remarkable vocal realism and ultra-wide dispersion for broad coverage. Dual force-canceling 5.5" woofers provide deep, low-distortion bass while minimizing structural vibration, directing more acoustic energy into the room and lowering the noise floor for greater performance.
38 Configurable Looks
MartinLogan offers 38 curated aesthetic configurations built around your chosen aperture size. VAS Speakers include round and square trims in Seamless (mud-in), Minimal, and Wide styles, plus flush or extended-mount grille options. Choose a 3", 3.5", or 4" grille for 12 unique looks per size. VAS Subwoofers add two vent-style trims, allowing them to match VAS Speakers or blend seamlessly into the ceiling as a discreet air vent.
Adjustable Port Offset
Both Variable Aperture models feature an innovative Adjustable Port Offset design that maximizes installation flexibility. The aperture can be positioned left, right, or center within the housing to accommodate visual and structural requirements. Combined with adjustable mounting brackets, this allows precise alignment for a clean, seamless installation and a perfectly finished appearance.
Adjustable Mounting Brackets
In combination with the Adjustable Port Offset feature, the bracket system provides unmatched flexibility within the ceiling joist bay. With support for floor joist spacing from 12" to 24" on center, Variable Aperture System models work in a wide variety of builds and designs.
Optimized for the MartinLogan Power Ecosystem
Custom DSP presets developed for the MartinLogan MP500 V2 and MDA8/MDA16 amplifiers maximize sound quality, output, and system efficiency. With presets engaged, each amplifier channel can safely drive up to two VAS Speakers, while the MP500 V2 can power dual subwoofers—supporting up to four VAS Subwoofers from just 1U of rack space. An 8-ohm impedance ensures compatibility with many high-performance third-party amplifiers.

The flagship of the series, and largest “LCR” model in the Motion XT CI series includes a unique feature that brings its performance level up even higher. In addition to the FMT XT tweeter, and dual 6.5” woven Kevlar Nomex-backed bass drivers, the XTW6-LCR has a dedicated 6.5” midrange driver that elevates its acoustic performance to rival that of traditional floor standing speakers. With a rotating tweeter housing, the XTW6-LCR can be used horizontally when needed, and is the perfect choice for systems desiring a higher level of performance without the large footprint of a tower speaker. The MartinLogan Motion XT CI series takes performance to the next level over Motion CI. The Folded Motion XT tweeter gives each model in the Motion XT series even more of the clarity, output, and efficiency that the standard size FMT is famous for. With Motion XT, we wanted to increase all aspects of performance over the Motion series, so we didn’t just stop at the tweeter. All Motion XT models feature woven Kevlar woofers for increased rigidity and lightness which translates into better sound. In addition to the larger tweeter, and lighter, stronger woofers, MartinLogan’s design and engineering team has fitted the Motion XT series with a more substantial chassis to strengthen the speaker and provide a more accurate sound, like a better cabinet on a traditional speaker. With Motion XT CI, the difference is in the details. No matter which Motion XT CI speaker you choose for your room, rest assured they are designed to provide a consistently high level of performance and can easily be used with other MartinLogan speakers to make creating the perfect system for your unique listening space that much easier.

The 4th generation Motion Series ushers in a new era of design and aesthetics for MartinLogan. The three modern, yet timeless, colorways can compliment any room while being a focal point if so desired. Motion evokes a unique look and sound, pairing high-performance woofers with exclusive Folded Motion Tweeter technology, a staple of MartinLogan products. The Motion Waveguide enhances the Controlled Dispersion of the Gen2 Folded Motion Tweeter to a generous 90°(Vertical) by 90°(Horizontal) to accommodate a wide range of seating and speaker placement options, while avoiding clarity destroying sound reflections within the environment.
