The 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.
 
The IC-3AW in-ceiling speaker offers trademark MartinLogan sound in areas where humidity prevents installation of conventional speakers. The conformal coating applied to the crossover maximizes water-resistant properties and the grille is specially coated to add material stability during extended periods of exposure to moisture.
