Product Description
The MartinLogan Helos 12 is a high-performance in-ceiling loudspeaker engineered to bring audiophile-grade sound to your home's architecture. Unlike entry-level models, the Helos 12 features a high-excursion 6.5-inch aluminum cone woofer. Aluminum's inherent stiffness and low mass allow the driver to respond with incredible precision, delivering deep, clean bass and a transparent midrange that remains consistent even at high volume levels.
Complementing the powerful woofer is a 1-inch soft-dome tweeter designed for smooth and natural high-frequency reproduction. This combination provides a wide frequency response of 47 Hz to 20 kHz, ensuring that you hear every detail of your music or film soundtracks. With a robust power range of up to 200 watts, this speaker is capable of filling large rooms with rich, dynamic sound, making it a top-tier choice for primary LCR channels or high-end multi-room audio systems.
The Helos 12 is built with professional installation in mind, featuring a round profile and a micro-perforated magnetic grille that sits nearly flush with the ceiling. The grille is fully paintable, allowing the speaker to disappear into your interior design. Whether you are building a dedicated media room or a luxury whole-home audio network, the Helos 12 delivers the legendary performance and refined engineering that MartinLogan is known for.

What are the benefits of an aluminum woofer?
Aluminum is much stiffer than paper or plastic, which means the woofer maintains its shape better during heavy use. This results in much lower distortion and a faster, more accurate bass response.
Can I use this speaker for my main front channels?
Yes. Due to its high power handling and wide frequency range, the Helos 12 is an excellent choice for front Left, Center, or Right (LCR) channels in an in-ceiling home theater setup.
Does it come with a back box?
This model does not include a built-in back box. If you need to control sound leakage to the floor above, we recommend installing a separate acoustic back box during the installation process.
