Description
MartinLogan IC6 – 6.5-Inch In-Ceiling Speaker (Single)
The MartinLogan IC6 is a high-performance two-way architectural in-ceiling loudspeaker, designed to provide exceptional sound quality while blending discreetly into residential interiors.
Part of MartinLogan’s Installer Series, the IC6 combines a 6.5-inch mineral-filled polypropylene bass/midrange driver with a 0.75-inch titanium dome tweeter, delivering clear vocals, detailed high frequencies and balanced musical reproduction.
Ideal for multi-room audio, home cinema and everyday music listening, the IC6 provides an elegant solution for rooms where traditional loudspeakers are impractical or visually intrusive.
Sold individually – price is for one speaker.
High-Performance 6.5-Inch Bass/Midrange Driver
The IC6 features a 6.5-inch mineral-filled polypropylene cone woofer with a computer-optimised magnetic structure.
Designed for controlled bass reproduction and natural midrange performance, the driver delivers clear and engaging sound for music, television and home entertainment.
Titanium Dome Tweeter
A 0.75-inch titanium dome tweeter provides detailed high-frequency reproduction.
Ferrofluid damping and cooling help maintain consistent performance, while its design provides clear sound across a broad listening area.
MartinLogan Vojtko Crossover Technology
The IC6 incorporates MartinLogan’s proprietary Vojtko crossover topology, using carefully selected components to integrate the woofer and tweeter smoothly.
This contributes to accurate musical reproduction, natural vocals and excellent detail.
Discreet, Low-Profile Ceiling Design
The IC6 features a paintable, micro-perforated magnetic grille with a virtually bezel-free appearance.
Once installed, the speaker projects only approximately 8mm below the finished ceiling surface, creating a clean architectural finish.
An optional square grille is available separately for installations requiring a different aesthetic.
Secure Architectural Installation
MartinLogan’s integrated mounting-lock system secures the speaker within a suitable ceiling opening.
A full-size installation template assists with accurate placement and preparation.
The IC6 is a passive speaker and requires a compatible external amplifier.
Multi-Room Audio & Control4 Integration
The MartinLogan IC6 is ideal for distributed audio installations where music is required throughout multiple rooms without visible floorstanding or bookshelf speakers.
When connected to suitable amplification, the IC6 can form part of a professionally designed Control4 smart home or multi-room audio system.
Typical applications include:
- Living rooms and lounges
- Kitchens and dining rooms
- Bedrooms and dressing rooms
- Home cinema surround and overhead speaker installations
- Multi-room music systems
- Smart home audio installations

Solutions Meet Performance
Manufactured to the highest standards of quality and performance, the new Installer Series by MartinLogan is a line of affordable, high-performance, ultra-low-profile custom installation in-ceiling and in-wall speakers. Featuring titanium dome tweeters and mineral-filled polypropylene drivers, each model comes with a remarkably robust mounting-lock system and paintable micro-perf, bezel-free grilles for a nearly invisible installation. Two all-weather models extended usage to high humidity areas. Pre-installation brackets are available for all models and square grilles are available for select in-ceiling models.
Titanium Dome Tweeters and Poly Cone Woofers
Titanium dome tweeters used throughout the Installer Series are ferrofluid damped and cooled for smooth high-frequency performance with amazing clarity across a wide listening area. Mineral-filled polypropylene cone bass/midrange drivers feature robust computer-optimized ferrite magnets and high-power motor structures to deliver detailed midrange performance and clean, extended bass response.
Micro-Perforated Grilles
Installer Series speakers feature ultra-low profile, paintable, micro-perforated grilles with no visible bezel for a near invisible integration into any wall or ceiling. A series of powerful magnets hidden inside the speaker quickly secure grilles into place, reducing the risk of warping or damage during installation. To match modern aesthetics, optional square grilles are available for most in-ceiling models (excludes all-weather versions).
Precision Crossovers & Spring-Loaded Binding Posts
Carefully hand-built using only the finest polyester capacitors and air-core coils, Installer Series crossovers employ MartinLogan’s proprietary Vojtko topology for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source. Spring-loaded binding posts feature a larger wire access hole and connect via banana plug, pin, or 12AWG bare wire.
Robust Mounting-Lock System
A simple, yet robust mounting-lock system allows quick, trouble-free installation. Pocketed screw holes help hold the drill steady, making installation a snap. When not in use, mounting locks are held securely within a self-contained housing. When moved into place, they couple the chassis firmly to the ceiling or wall, increasing the rigidity of surfaces. If ever removed, the locks retract and latch back in their housings. Each speaker includes a full-size installation template featuring quick-reference instructions, and die-cut guides for marking the cutout hole.
