Solid midrange performance comes courtesy of a 3-1/2" mineral-filled polypropylene woofer, while a 3/4" titanium dome tweeter dishes out clear, smooth highs.

The enclosed design helps deliver focused, well-balanced sound in your ceiling.

A built-in enclosure elevates performance

One of my favorite features of the IC3 is the integrated back-box that's built onto the speaker. This carefully designed enclosure helps it deliver consistently focused, well-balanced sound no matter what kind of space is above it in your ceiling. It also keeps dust and dirt out of your speaker.

Features

Installer Series: 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-Way Driver Design: The IC3 in-ceiling loudspeaker utilizes a two-way driver design with a 0.75" titanium dome tweeter and a 3.5" mineral-filled poly cone woofer. The titanium dome tweeter is ferrofluid damped and cooled for smooth high-frequency performance with amazing clarity across a wide listening area. The mineral-filled polypropylene cone bass/midrange driver features a robust computer-optimized ferrite magnet and a high-power motor structure to deliver detailed midrange performance and clean, extended bass response. The unique woofer design, molded directly on to the speaker's chassis, maximizes woofer size for incredible performance in an extremely small size.

Precision Crossover: Carefully hand-built using only the finest polyester capacitors and air-core coils, Installer Series crossovers employ MartinLogan's proprietary Vojtko topology for extremely 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: Spring-loaded binding posts feature a larger wire access hole and connect via banana plug (single/dual), pin-connector, or bare speaker wire (up to 12AWG). The spring-loaded binding posts are gold-plated for excellent signal transmission and resistance to corrosion.

Micro-Perforated Grilles: MartinLogan's Installer Series speakers feature ultra-low profile, paintable, micro-perforated grilles with no visible bezel for a near invisible integration into almost any ceiling. A series of powerful magnets hidden inside the speaker quickly secure grilles into place, reducing the risk of warping or damage during installation. The outer frame of the speaker with the grille installed measures 4.125" (diameter) x 0.25" (depth).

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, 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 cut guides for marking the cutout hole. The IC3 requires a round cutout that measures 3.75" (diameter) x 3.9375" (depth). There needs to be at least 0.5" around the cutout behind the ceiling to accommodate the three mounting locks.

Applications: The MartinLogan IC3 in-ceiling loudspeaker is the perfect blend of performance and lifestyle. The IC3 is perfect for almost any application where a discrete solution is ideal - from a hallway or kitchen to Atmos channels in a home theater.
