The Helos 20 delivers legendary MartinLogan quality and performance in a compact, high-resolution in-ceiling loudspeaker. Featuring dual 0.75-inch neodymium soft dome tweeters, a high-rigidity aluminum cone woofer, and proprietary Vojtko crossover topology, Helos 20 effortlessly provides solid imaging with extreme sonic accuracy.

Multi Application Use
Helos 20 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.

Stereo Sound From One Speaker
Helos 20 features dual tweeters and a dual voice coil woofer. This design allows the speaker to provide stereo sound from a single speaker, ideal for use in small rooms such as bathrooms, small offices, entryways, and kitchens. Helos 20 also bridges to deliver mono sound reproduction with wide dispersion.

Low-Distortion 6.5-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 20 delivers a precise low-end with accuracy, authority and extension uncommon to traditional in-ceiling loudspeakers.

Precision-Built, Advanced-Topology 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.

Quick, Trouble-Free Installation
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 20 speaker comes with a full-size installation template that features quick-reference instructions, and die-cut guides for marking the cutout hole.

Paintable Frame and Grill Cover
A paintable frame and grill endows the Helos 20 with the flexibility to complement any decor.
