MartinLogan VA4ICSPKR 4" Variable Aperture Full-Range 2-Way In-Ceiling Speaker System
- 4” In-Ceiling Speaker w/ Dual 5.5” Woofers & a 2” High-Output Driver
- 38 Configurable Looks
- Adjustable Port Offset
Overview
In luxury distributed audio, the challenge is delivering consistent, high-quality bass without the visual clutter of large grilles or the complexity of dedicated subwoofers. The MartinLogan Variable Aperture System (VAS) solves this by delivering high-output, full-range performance through 3”, 3.5”, or 4” apertures that match standard recessed lighting.
To create an airy, effortless soundstage from a discrete opening, we use a specialized 2″ high-output, wide bandwidth aluminum driver.
By dedicating this precision driver to the critical midrange and high frequencies, we deliver vocal realism and a sense of scale completely unexpected from its size. Ultra wide dispersion ensures a large coverage area, making it ideal for distributed audio. Low frequencies are handled by dual, balanced 5.5” woofers using a force-canceling configuration. By mounting the woofers in an opposing, balanced array, mechanical vibrations are cancelled at the source.
This ensures energy is directed into the room as pure, low-distortion bass while the ceiling structure remains quiet.
Adapt to any room layout on the fly. With our field-adjustable port, you can easily shift the configuration to the Left, Right, or Center at any time.
Features
- 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 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.
- 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.
