Our take on the MartinLogan Helos™ 22

by Dave Bar
MartinLogan

Stereo sound from a single speaker

Don't have room for separate stereo speakers? No problem. MartinLogan's space-saving Helos 22 makes it easy to enjoy rich stereo sound from a single in-ceiling installation. It's ideal for use in areas where multiple in-ceiling speakers may be impractical (or impossible), such as hallways, entryways, small offices, or walk-in closets. 

MartinLogan Helos 22 in-ceiling speaker

Made from the right stuff for superlative performance

The Helos 22 features two high-resolution 3/4" soft dome tweeters for sparkling clear, stereo highs, and a dual-voice-coil 6-1/2" aluminum cone woofer for dynamic midrange and tight, responsive bass. A hand-built, audiophile-grade crossover ensures seamless driver integration for low-distortion, high-accuracy sound.

Installer-friendly design

The Helos 22's robust mounting-lock system allows quick, trouble-free installation, providing firm coupling of the speaker's chassis to the ceiling. And this speaker is practically invisible thanks to an ultra-low profile, micro-perforated grille and hidden bezel. Magnets hold the grille in place, reducing the risk of warping or damage during installation. The Helos 22 can also be bridged to mono mode for wide dispersion sound reproduction in a distributed audio system.
