GA43 4-ch 750w Power Amplifiers with DSP

GPX

2x18" Subwoofer + 4x12" Slim Array System (Passive)

GPX is our top of the line high performance passive system and comprises of a 2x18” subwoofer combined with GH412, our 4x12” coaxial slim array with K-array™ SAT® (Slim Array Technology), PAT® (Pure Array Technology) and a stainless steel cabinet. 

This system can be driven by GPXA active system in a stereo configuration or by GA46 power amplifiers.

Thanks to its extreme performance and the compact format of the array, this system works in a stack configuration, with the array on top of the subwoofer. It is also possible to fly GH412 with our GH-FLY flybar accessory, or place it on the ground with our GH-BASE accessory.

Perfect for high SPL outdoor/indoor applications in large venues both for rental and permanent installations for touring, auditoriums, stadia, clubs, theme parks.

User Tip: optimize the cost and combine the system with the active model whether it is for stereo configurations or if need to extend the satellite cluster to form an array.
