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.
Traditional bass performance requires large woofers, often at odds with modern ceiling aesthetics. VAS eliminates that compromise with a concealed, high-volume enclosure hidden above the ceiling. The result is the bass, dynamics, and impact of a much larger subwoofer delivered through a discreet aperture that blends seamlessly with designer LED downlights—allowing rooms to look beautiful and sound breathtaking.
The same visual DNA as the Variable Aperture Speaker, optimized for high-impact bass performance. By removing the midrange/high-frequency driver, it focuses entirely on low-end authority. Dual 5.5" woofers feature upgraded motor structures, specialized voice coils, and higher power handling to deliver the weight and punch of a larger subwoofer through a discreet opening, while a force-canceling design minimizes vibration and keeps the ceiling quiet.
MartinLogan has curated 38 aesthetic variations around your choice of aperture size. The VAS Subwoofer includes round and square trims in Seamless (Mud-In), Minimal, and Wide styles, plus flush or extended grille mounting options. Choose a 3", 3.5", or 4" grille to access 12 looks per aperture size. Additional Vent Style trims allow the VAS Subwoofer to match VAS Speakers, blend with other in-ceiling speakers, or disappear behind the appearance of an air vent.
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.
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.
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.
