The GSL12 is a premier line array module tailored for large-scale audio broadcasting. With the ability to fly up to twenty-four GSL12 units vertically, it offers a consistent 120° horizontal directivity dispersion.

This module boasts two forward-facing 14" neodymium LF drivers and a pair of 10" neodymium LF drivers on the sides. Its coaxial mid-high section encompasses a 10" MF horn and three 1.4" exit compression drivers, each with a 3.4" voice coil, all linked to a specialized wave shaping device. Cabinet splay angles are adjustable from 0° to 7° in 1° steps. These speakers are powered by dual channels from a suitable d&b amplifier; one channel for the 14” LF drivers and the other for the remaining components which are connected through a passive crossover.

This arrangement facilitates a seamless crossover with clear transitions between bands, ensuring uniform and precise horizontal sound distribution. The combination of the primary and lateral firing LF drivers ensures directive control, ranging from 45 Hz up to 18 kHz. Crafted from marine-grade plywood, these cabinets feature a durable and weather-resistant PCP (Polyurea Cabinet Protection) finish.

The exterior, both front and sides, is shielded by sturdy metal grilles, complemented by a sound-permeable and water-resistant fabric. For ease of handling, recessed grips are embedded on each side, with extra handles available at the back.
