MartinLogan Helos 12 In-Ceiling Speaker - White - Each

What You Need to Know

The MartinLogan Helos 12 solves the fundamental problem of in-ceiling speakers: the sound fires at the floor, not at you. Its 1-inch neodymium soft dome tweeter is mounted on a pivoting stem that aims directly at the primary listening position, delivering genuinely high-resolution sound at the sweet spot while wide dispersion keeps the whole room covered. A 6.5-inch high-rigidity aluminum cone woofer with cast basket and extended-throw drive assembly carries the music down to 47Hz.

MartinLogan's hand-built Vojtko crossover—air-core coils and polyester capacitors—keeps distortion vanishingly low, and the aimable design makes the Helos 12 ideal for any channel in a traditional or object-based surround system (Dolby Atmos/DTS:X): fronts, center, sides, rears, or overhead. Installation is quick with the mounting-lock system and full-size template, and the magnetic, paintable, bezel-free micro-perf grille projects just 0.2 inches.
