The C6 is a compact, high performance, multipurpose loudspeaker employing a premium 6.5″ coaxial device with an integrated 1″ compression driver.

Its distinct enclosure design and comprehensive range of accessories make it an excellent choice for rapid deployment to almost any application, from stage monitoring, to front fills, to permanent installation.

The C6 delivers impressive SPL output, yeilding highly capable sound reinforcement from a compact and versatile package. Its impressive fidelity makes it perfectly compatible with the larger C12, M12X, M15X, and LA28 loudspeaker systems.

The C6 cabinet features an impact resistant polyurethane paint finish, and an integrated handle. The loudspeaker system is available as weatherized (-X) or in white (-W) or custom colors (-C). The weatherized option provides and IP54 rating.

The optimum processed loudspeaker solution for the RMS-Acoustics C6 is the Linea Research 44M06 series and 44C06 series amplifiers, with propriety presets provided by RMS-Acoustics.

All other Linea Research M series and C series amplifiers can also be used.
