Feature

• Installer Friendly – 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.
• Stealthy Grilles – MartinLogan s new Helos speakers feature ultra-low profile, paintable micro perforated grilles with no visible bezel for an near invisible integration into any wall or ceiling. A magnetic system secures grilles easily into place, reducing the risk of warping or damage during installation.
• 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.
• Multi Application Use – Helos 12 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.
