GSL12 Loudspeaker

The GSL12 is a high-performance line array loudspeaker module engineered specifically for large-scale sound reinforcement applications. Designed to be deployed in vertical arrays of up to twenty-four units, the GSL12 offers a horizontal dispersion of 120° with constant directivity, ensuring uniform coverage across wide audience areas.

Each GSL12 module features a dual low-frequency configuration comprising two forward-facing 14-inch neodymium drivers alongside a pair of 10-inch neodymium drivers positioned on the sides. The mid and high-frequency components are housed in a coaxial arrangement, which includes a 10-inch driver on a dedicated MF horn and three high-frequency compression drivers with 1.4-inch exits and 3.4-inch voice coils, coupled to a precisely engineered wave shaping device.

Cabinet splay angles are adjustable from 0° to 7°, in 1° steps, enabling accurate array configuration to suit varying venue requirements. The GSL12 operates in an active configuration using two amplifier channels: one dedicated to the 14-inch LF drivers and the other powering the remaining components via an internal passive crossover. This driver and crossover design enables seamless integration across frequency bands, resulting in consistent horizontal coverage and precise directivity.

GSL12 Line Array Loudspeaker Module for Large-Scale Sound Reinforcement

 

 

The GSL12 is a professional-grade line array loudspeaker built for high-performance sound reinforcement in large-scale venues. Offering a precise 120° horizontal dispersion, it features an advanced driver configuration that delivers accurate, even coverage across the entire listening area.

Engineered for both touring and permanent installations, the GSL12 combines robust construction with innovative acoustic design to ensure long-term durability and consistent performance. With controlled directivity from 45 Hz to beyond 18 kHz, it provides clear, powerful audio suited to the most demanding environments.

As a specialist in large-scale loudspeaker systems, we supply trusted solutions like the GSL12, backed by expert guidance and support for professional audio application.

Optimised Driver Configuration for Full-Range Clarity
The GSL12 integrates dual 14" front-facing LF drivers, twin 10" side-mounted LF drivers, a 10" MF driver, and three HF compression drivers. This setup ensures seamless frequency response and clear, balanced sound across all output levels.
Wide 120° Horizontal Dispersion Pattern
Featuring a constant directivity design, the GSL12 delivers an even 120° horizontal coverage. This ensures uniform sound distribution, even in wide venues or outdoor environments.
Precise Directivity from 45 Hz to 18 kHz
Thanks to the unique LF driver arrangement, the GSL12 maintains controlled directivity throughout its full operating range. This allows for accurate sound reinforcement with minimal off-axis coloration.
Durable, Road-Ready Construction
Crafted from marine-grade plywood with a PCP (Polyurea Cabinet Protection) finish, the GSL12 is built to withstand the rigours of touring. Integrated handles and weather-resistant design enhance handling and durability.
