GSL12 loudspeaker

The GSL12 is a line array module specifically designed for large-scale sound reinforcement. Up to twenty-four GSL12 loudspeakers can be flown in vertical columns producing a 120° constant directivity dispersion pattern in the horizontal plane. The GSL8 houses two 14″ neodymium forward-facing LF drivers and two side-firing 10″ neodymium LF drivers. A coaxial mid-high section contains an MF horn with a 10″ driver and three 1.4″ exit, 3.4″ voice coil HF compression drivers mounted to a dedicated wave-shaping device. Splay angles between cabinets can range from 0° to 7° in 1° increments. The loudspeakers are driven actively by two channels of an appropriate d&b amplifier, one channel powering the 14” LF drivers, the second channel powers all other components, these are passively crossed over. This component geometry allows for a smooth crossover design with well-defined overlaps between adjacent bands providing consistent, even, and very accurate horizontal dispersion. Due to the arrangement of the front and side-firing LF drivers, accurate directivity control is maintained from 45 Hz to above 18 kHz. The cabinets are constructed from marine plywood and have an impact and weather-protected PCP (Polyurea Cabinet Protection) finish. The front and side panels incorporate rigid metal grills backed by an acoustically transparent and water-repellent fabric. Each side panel incorporates a recessed handle, with additional handles are provided at the rear.
