Helos 100

Helos 100 in a home setting

Continuing in the tradition of MartinLogan's critically acclaimed in-wall speakers (Voyage, Passage, and Ticket), our dedicated in-house design and engineering team looked to the sky. The Helos 100 delivers legendary MartinLogan quality and performance in a compact, high-resolution in-ceiling loudspeaker. Featuring a 1-inch neodymium soft dome tweeter, high-rigidity aluminum cone woofer, and proprietary Vojtko crossover topology, Helos 100 effortlessly provides solid imaging with extreme sonic accuracy. An acoustic contour switch tailors dispersion assuring a top-notch performance in any installation.

Quick, Trouble-Free Installation

Constant control, die-cast aluminum mounting locks

A robust mounting-lock system allows quick, trouble-free installation. When not in use, the constant-control, die-cast 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 100 speaker comes with a full-size installation template that features quick-reference instructions, and die-cut guides for marking the cutout hole.

Low-Distortion Aluminum-Cone Woofer

8-inch low-distortion aluminum-cone woofer

Utilizing a high-excursion, high-resolution state-of-the-art woofer specially designed for accurate in-wall bass performance, the Helos 100 delivers a precise low-end with accuracy, authority and extension uncommon to traditional in-ceiling loudspeakers.

Vojtko™ Crossover

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.
