Introducing GP18A, a high-performance active pro-audio system that combines a powerful 18" powered subwoofer with 3 modular 8x2" line-array elements featuring K-array™ PAT® technology (Pure Array Technology). The column consists of 3 interchangeable array modules with an alternating horizontal inclination of each driver, offering a 140° wide horizontal dispersion angle for an immersive sound stage.

Ideal for low-impact indoor and outdoor events such as concerts, auditoriums, bars, and clubs, the GP18A system is designed for both rental and permanent installations. This active system, featuring Powersoft™ DSP and power module with Ethernet remote control and Armonia™ control software, allows for seamless control and impressive audio performance.

User Tip: Maximize your budget and system flexibility by combining GP18A with the passive GP18 model for stereo configurations or distributed sound.
