 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.

Designed to Aim at the Listening Position

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.

Installer Friendly

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& 39;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.

Stealthy Grilles

MartinLogan& 39;s new architectural speakers feature ultra-low profile, paintable micro perforated grilles with no visible bezel for an near invisible integration into any wall or ceiling. A magnetic system secures grilles easily into place, reducing the risk of warping or damage during installation.

Precision-Built,Advanced-Topology Vojtko™ Crossover

Carefully hand-built using only the finest polyester capacitors and air-core coils, the crossover employ& 39;s MartinLogan& 39;s proprietary Vojtko topology for vanishingly 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.

Helos 12 is suitable for any application in average to small rooms. Ideal for use in a multi-channel home theater as a front, center, or surround speaker,  in a kitchen as 2-channel stereo speaker, or in a hallway as a single-channel distributed audio speaker.
