Product Overview

The MartinLogan IC6-ST is a high-performance 6. 5-inch in-ceiling stereo speaker designed to deliver full left and right channel stereo sound from a single location.

Key Features

Dual Tweeters: Twin 0.75-inch titanium dome tweeters are ferrofluid-damped and cooled to ensure smooth, high-frequency response with exceptional clarity across a wide dispersion field
High-Excursion Woofer: A 6.5-inch mineral-filled polypropylene woofer utilizes a high-power motor structure and robust ferrite magnets to deliver articulate mid-range vocals and clean, controlled bass response down to 52 Hz
Vojtko Crossover Topology: Hand-built using high-grade air-core coils and polyester capacitors, MartinLogan s proprietary crossover network maintains low distortion and seamless driver integration

Dual-Stereo Performance from a Single Speaker

Part of MartinLogan’s Installer Series, the IC6-ST provides an ideal solution for rooms where installing a pair of traditional stereo speakers is impractical. Equipped with dual voice-coil technology and twin tweeters, it reproduces both left and right audio channels simultaneously from one flush-mount ceiling fixture. Alternatively, the speaker’s input terminals can be bridged for mono operation to achieve broad sound coverage in larger spaces.

Premium Acoustic Components

  • Dual Tweeters: Twin 0.75-inch titanium dome tweeters are ferrofluid-damped and cooled to ensure smooth, high-frequency response with exceptional clarity across a wide dispersion field.
  • High-Excursion Woofer: A 6.5-inch mineral-filled polypropylene woofer utilizes a high-power motor structure and robust ferrite magnets to deliver articulate mid-range vocals and clean, controlled bass response down to 52 Hz.
  • Vojtko Crossover Topology: Hand-built using high-grade air-core coils and polyester capacitors, MartinLogan’s proprietary crossover network maintains low distortion and seamless driver integration.

Architectural Design & Quick Installation

Engineered for custom installation, the IC6-ST features a bezel-free, micro-perforated magnetic grille that can be painted to blend invisibly into any ceiling. A robust mounting-lock system with pocketed screw holes stabilizes drill bits during setup, securing the speaker tightly behind drywall with minimal effort.
