Product Description The MartinLogan Installer Series IC6-ST is a smart audio solution designed to deliver a complete stereo experience from a single in-ceiling speaker. Ideal for smaller rooms or transitional spaces like hallways and laundry rooms, the IC6-ST utilizes a dual-tweeter design to provide both left and right audio channels simultaneously. This ensures a rich, full-range soundstage in areas where installing a traditional pair of speakers is impractical.At the core of the IC6-ST is a high-performance 6.5-inch mineral-filled polypropylene woofer. This driver is engineered for durability and precision, providing a smooth mid-range and balanced bass response. The dual 0.75-inch hard-dome tweeters work in tandem to capture high-frequency details with clarity, ensuring that your background music sounds vibrant and well-defined. With a shallow 3.5-inch mounting depth, it fits easily into standard ceiling cavities for a hassle-free installation.Like all models in the Installer Series, the IC6-ST features a micro-perforated magnetic grille that sits nearly flush with the ceiling. The grille is fully paintable, allowing the speaker to blend perfectly with your home's interior design. Whether you are building a professional whole-home audio network or simply upgrading a single room, the MartinLogan IC6-ST offers the perfect combination of technical innovation and architectural discretion.

In small rooms, yes. Because it has two tweeters and dual voice coils, it can play both the left and right channels of a stereo signal from one unit. How do I wire a stereo speaker? Unlike standard speakers, you will typically run two sets of speaker wires (Left and Right) from your amplifier to the IC6-ST to utilize its stereo capabilities. Can I use this as a normal mono speaker? While designed for stereo, it can be configured for mono applications, but its primary benefit is providing a full soundstage from a single mounting point.
