Passive 12-inch 2-Way Loudspeaker
Featuring legendary Mackie sound quality and durability, the lightweight C Series 2-way Precision Passive loudspeakers deliver optimum performance in portable PA, stage monitor and permanent installation applications. The Mackie C-300Z is a full-range portable loudspeaker providing high-output, ultra-wide dispersion and low-distortion performance in a compact, composite molded enclosure. A heat-treated titanium compression driver with multi-cell aperture directs pristine highs through an exponential highfrequency waveguide, allowing for ultra-wide dispersion of highs and mids. In fact, the C 300Z can deliver clear, smooth sound to audience members up to 45° off axis.

The custom-designed high-power 12-inch woofer can take a pounding, plus its 3-inch voice coil allows the driver to run cooler, delivering consistent performance even after long hours of use at near peak volumes. The crossover in the C300Z is a unique Low Impedance Compensated Crossover (LICC) design. With EQ and crossover points meticulously chosen so that beamwidth patterns match in both drivers, C-300Z loudspeakers offer natural sound at all volume levels.

The center of gravity, handle locations, handle design, position of fly-points and ease of use have been ergonomically designed. There is also an integrated pole mount on the bottom of the cabinet and a weather-resistant steel grille. The asymmetrical trapezoidal cabinet has been designed to provide an ideal floor monitoring position. The cabinet is constructed of high-pressure injected polypropylene. The enclosure features reinforcement ribbing and structural strengthening resulting in a strong, super-rigid design providing ideal acoustical characteristics.
