The MartinLogan IW5-LCR is a versatile in-wall speaker designed specifically for left, center, and right channel applications in high-performance home theater systems. Featuring dual 5.5-inch mineral-filled polypropylene woofers and a precision-engineered 0.75-inch titanium dome tweeter, it delivers powerful midrange performance, extended bass response, and articulate high frequencies while maintaining the clean aesthetics of an architectural installation.

Engineered with MartinLogan's proprietary Vojtko crossover topology, the IW5-LCR provides seamless integration between its drivers for exceptional clarity, low distortion, and a balanced soundstage. The dual-woofer configuration increases dynamic output and low-frequency extension, making it especially well-suited for demanding movie soundtracks and multichannel music systems.

Designed for custom installation, the IW5-LCR features a robust mounting-lock system that ensures a secure fit while increasing wall rigidity for improved acoustic performance. Its ultra-low-profile magnetic micro-perforated grille can be painted to match any décor, allowing the speaker to virtually disappear into the wall without compromising sound quality.

Whether used as the front LCR stage of a dedicated home theater or as surround speakers in a premium architectural audio system, the IW5-LCR combines discreet installation with dynamic, room-filling performance. Its flexible orientation, premium driver materials, and proven MartinLogan engineering make it an outstanding solution for custom home cinema installations.
