The Helos 12 delivers legendary MartinLogan quality and performance in a compact, high-resolution in-ceiling loudspeaker. Helos 12 effortlessly provides extreme sonic accuracy from its a 1-inch neodymium soft dome tweeter mounted in an aimable stem, a high-rigidity aluminum cone woofer, and proprietary Vojtko crossover topology.
Helos 12 features a high-resolution neodymium tweeter mounted on a pivoting tweeter stem that easily aims at the primary listening location. This design allows the audience to enjoy the highest levels of in-ceiling audio performance, while still providing rich, detailed sound throughout the entire room.
A robust mounting-lock system allows quick, trouble-free installation. When not in use, the constant-control mounting locks are held securely within a self-contained housing. When moved into place during installation, they couple the speaker's chassis firmly to the ceiling. And if the speaker is ever removed, the locks retract and latch themselves back in their housings.
Each Helos 12 speaker comes with a full-size installation template that features quick-reference instructions, and die-cut guides for marking the cutout hole.
