Introducing our high-performance audio system, GPXA, designed to meet the needs of audio tech enthusiasts who demand the best in sound quality. This top-of-the-line active system boasts a powerful 2x18" subwoofer paired with GH412, our sleek 4x12" passive coaxial line-array element featuring K-array™ SAT® (Slim Array Technology) and PAT® (Pure Array Technology), all housed in a durable stainless steel cabinet.

Equipped with a poweful 4x1500W RMS amplifier, GPXA can drive a GPX passive system in stereo configuration, utilizing the advanced Powersoft™ DSP and power module, which can be controlled via ethernet with the user-friendly Armonia™ control software.

Thanks to its remarkable performance and compact design, GPXA can be configured in a stack arrangement, with the array atop the subwoofer. Alternatively, GH412 can be flown using our GH-FLY flybar accessory or placed on the ground with the GH-BASE accessory.

This audio system is ideal for high SPL indoor and outdoor applications in large venues such as touring, auditoriums, stadia, clubs, and theme parks, both for rental and permanent installations. For a cost-effective option, users can combine GPXA with the passive model to achieve a stereo configuration or to extend the satellite cluster and form an array.

So if you're looking for the ultimate audio experience with exceptional sound quality, GPXA is the perfect choice for you!
