An acoustic contour switch tailors dispersion assuring a top-notch performance in any installation.
Designed to Aim at the Listening Position
Helos 100 features a high-resolution neodymium tweeter mounted on a rigid angled tweeter stem and an aluminum cone woofer mounted at an angle. Orientating the tweeter stem towards the primary listening location allows the audience to enjoy the highest levels of in-ceiling audio performance, while still providing rich, detailed sound throughout the entire room. To aim the Helos 100, simply turn the entire speaker assembly so the tweeter points at the primary listening location.
High-Resolution 8-Inch 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.
Precision-Built Advanced-Technology 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.
Acoustic Contour Switch Fine Tunes Dispersion
A unique acoustic contour switch tailors high-frequency performance to provide either spot or wide dispersion, assuring a top-notch performance in any installation.
Quick, No-Hassle Installation
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.
