RK1-169

Reference Series 6x9” Coaxial Speaker Performance

Upgrade your in-car audio experience with the MB Quart RK1-169 Reference Series 6x9-Inch 2-Way Coaxial Speakers. Designed for rich musical reproduction and powerful output, these speakers deliver a refined listening experience with enhanced clarity, strong midbass, and detailed high-frequency performance. With 200 watts peak power handling (100W per speaker) and 50 watts RMS per speaker, they provide a balanced and dynamic upgrade over factory systems.

The coaxial 2-way design integrates a woofer and tweeter into one efficient unit, making installation simple while still delivering full-range sound performance suitable for everyday driving and high-energy music playback.

Advanced Materials for Clean, Powerful Sound

The MB Quart RK1-169 speakers are engineered with high-quality materials to ensure durability and accurate sound reproduction. The 0.75-inch dome tweeters with WideSphere Technology deliver smooth, extended high-frequency response and improved off-axis dispersion, creating a wider and more immersive soundstage.

A lightweight curvilinear cone design provides strong structural integrity while reducing distortion from cone flexing, allowing for clean midrange and deep bass performance. The system is further enhanced by a built-in audiophile crossover, ensuring smooth frequency transitions between woofer and tweeter for balanced sound output.

High-temperature adhesives and molded polymer sealing gaskets improve durability and protect against vibration, dust, and moisture intrusion.

Reference Sound Engineering for Everyday Driving

The MB Quart Reference Series RK1-169 Speakers are designed to deliver dynamic, accurate sound with a focus on musical realism and bass impact. Engineered in collaboration with vehicle integration specialists, these speakers are optimized for a wide range of factory and aftermarket installations.

Their 4-ohm impedance ensures compatibility with most car audio systems, while the robust construction supports long-term reliability under varied driving conditions. The vented frame design helps manage heat buildup around the voice coil, improving efficiency and durability.

Whether upgrading factory speakers or building a custom system, the RK1-169 provides a clean, powerful, and well-balanced audio experience.
