The ISP Technologies Mongoose™ GSL12 speakers are a 3-way active speaker system with high output and low distortion.  The system comprises two boxes which are stacked to form a 4-element line.  The bottom box contains two vertically arrayed, high performance 12-inch speakers and two amplifier modules which contain 5 channels of amplification and an optimized electronic crossover.  The top box contains two more 12-inch speakers, a horn-loaded compression midrange, and two high frequency drivers.  The two boxes are interconnected by an 8-pole Speakon cable.  Use with subwoofers is highly recommended.  These two-box stacks are sold in mirror-image pairs.  The system can be expanded to 4 boxes per side by placing a right top upside down on a left top (and vice-versa), thereby aligning the LF, MF, and HF lines.  The system has tight vertical dispersion and is recommended for crowds, which cover vertical angles of 18 degrees or less.

     Use of a horn-loaded MF compression driver results in top-quality midrange clarity and throw, while use of 1-inch HF compression drivers results in extended highs and wide horizontal dispersion.  These compression drivers are of the very highest sensitivity (>110 dB/1W/1m).

     Standard with the system is a built-in 5-channel, 1700 Watt rms (total) amplifier/electronic crossover that is specifically designed for use with the speaker.  This amplifier features ISP’s patent pending DCAT high-current amplification technology.  A cooling fan automatically switches on when needed.
