7、this difference, all details in this manual apply to both models. The C300 is a portable two-way loudspeaker system, capable of extremely high sound pressure levels. The Transducers The C300 has a 12” high-power low- frequency woofer and a 1.75” mylar diaphragm high-output compression driver. The wo

The high-frequency compression driver is mounted on a multi-cell aperture loaded on a constant directivity horn, providing an ultra-wide, controlled dispersion pattern and precise reproduction o

Each driver has been specifically designed for optimum performance in a lightweight high-strength cabinet. The Crossover This unique Low Impedance Compensated Crossover (LICC) design places inductors in

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 fro
