High-Performance In-Ceiling For Small and Mid-Sized Rooms
The Helos 12 is a high-resolution in-ceiling loudspeaker featuring a 1-inch neodymium soft dome tweeter mounted in an aimable stem, 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.
MartinLogan's new Helos 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.
Carefully hand-built using only the finest polyester capacitors and air-core coils, the crossover employ's MartinLogan'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 use in small rooms. Designed for use as a single stereo speaker in distributed audio or a wide dispersion home theater surround.
