The MartinLogan IC3 is the most compact in-ceiling speaker in the Installer Series, engineered to deliver impressive audio performance in applications where space is limited. Its innovative design maximizes woofer size within an exceptionally small footprint, making it ideal for kitchens, hallways, bathrooms, multi-room audio systems, and Dolby Atmos® overhead channels without compromising sound quality.
Equipped with a 3.5-inch mineral-filled polypropylene woofer and a ferrofluid-cooled 0.75-inch titanium dome tweeter, the IC3 produces clean vocals, smooth high frequencies, and balanced midrange performance. MartinLogan's precision-engineered Vojtko crossover network ensures seamless integration between the drivers, delivering natural, low-distortion sound across a wide listening area.
Despite its compact size, the IC3 is built with the same premium construction found throughout the Installer Series. Die-cast aluminum mounting locks provide a secure installation, while the ultra-low-profile magnetic micro-perforated grille can be painted to blend virtually invisibly into any ceiling. Optional square grilles and pre-installation brackets offer additional flexibility for custom installations.
Designed for both residential and commercial environments, the IC3 delivers reliable performance for distributed audio and immersive home theater applications where discreet aesthetics are just as important as sound quality. Its combination of compact dimensions, premium materials, and MartinLogan engineering makes it an excellent choice for installations where traditional ceiling speakers simply won't fit.
