Mackie C300z Owner's Manual - Page 3

INTRODUCTION Thank you for choosing Mackie sound reinforcement loudspeakers. The C300z is a portable two-way loudspeaker system, specifically designed to complement our PPM Series line of professional powered mixers. They are capable of extremely high sound pressure levels, and designed to give you the best performance of any loudspeaker in its class and price range. The Transducers The C300z features a 12-inch high-power low-frequency woofer and a 1.75-inch titanium diaphragm high-output compression driver. The woofer incorporates technology used in largeformat touring systems and, with a massive, precision 3-inch voice coil, is virtually indestructible. The high-frequency compression driver is mounted on a multi-cell aperture loaded on a constant directivity horn, providing an ultrawide, controlled dispersion pattern and precise reproduction of the critical upper mid-range and high-frequencies. The result is an unbelievably smooth off-axis response that allows everyone in the audience to experience the same high-resolution audio no matter where they are seated. Each driver has been specifically designed by our engineers for optimum performance in a lightweight high-strength cabinet. The Crossover This unique Low Impedance Compensated Crossover (LICC) design places inductors in series with the woofer whose values are markedly lower than conventional designs. This reduces the amount of energy that is typically wasted as heat and increases the amount of energy that is transformed into real acoustic power. It also incorporates dynamic protection for the compression driver from non-linear signals. The Cabinet The C300z cabinet was designed to be the strongest molded composite cabinet on the planet. This material is as strong as a rhinoceros horn, and rigid enough to prevent unwanted vibrations and standing waves in the cabinet. It has built-in fly points for hanging, and a socket in the bottom for mounting on a tripod stand. Although it is an exceptional choice for installed sound situations, its light weight and durable finish also make it ideal for portable sound system use. The asymmetrical trapezoidal design of the cabinet also makes it easy to use as a floor wedge for stage monitor applications. The C300z offers a portable, lightweight solution for a variety of high-powered sound reinforcement applications.
