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-wall and in-ceiling 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.

LCR Configuration: The MartinLogan Install Series IW5-LCR is an in-wall LCR-type loudspeaker that can be used for left, center, or right channels in a home theater application. Its the perfect solution for an in-wall center-channel speaker.

Two-Way Driver Design: The IW5-LCR in-wall loudspeaker utilizes a two-way driver design with a 0.75" titanium dome tweeter and two 5.5" 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 drivers feature a robust computer-optimized ferrite magnet and a high-power motor structure to deliver detailed midrange performance and clean, extended bass response.

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 amost any wall. 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 12.6875" (w) x 9.3125" (h) x 0.3125" (d).

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 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 cut guides for marking the cutout hole. The IW5-LCR requires a rectangular cutout that measures 11.625" (w) x 8.25" (h) x 3.0" (d). There needs to be at least 1.0" around the cutout behind the wall to accommodate the seven mounting locks. The IW5-LCR can be mounted in the wall horizontally or vertically.
