About the Helos 12
The MartinLogan Helos 12 is a premium in-ceiling loudspeaker designed for high-performance audio in home theaters, kitchens, bedrooms, and distributed audio systems. It features a hand-built, audiophile-grade crossover network that ensures low-distortion, high-accuracy sound. The aimable neodymium tweeter can be pivoted to target sound toward your primary listening position, while the long-throw aluminum cone woofer delivers dynamic midrange and tight, responsive bass. The speaker includes an ultra-low profile, paintable micro-perforated grille with no visible bezel for near-invisible ceiling integration. A robust mounting-lock system enables quick, trouble-free installation with included full-size installation template and die-cut guides. The Helos 12 is ideal for small to mid-sized rooms and works excellently as part of Dolby Atmos or DTS:X object-based surround applications.
