GA43 4-ch 750w Power Amplifiers with DSP


18" Subwoofer + 24x2" Modular Column System (Passive)

This high performance system includes a 18” passive subwoofer combined with 3 modular 8x2” transducer array elements featuring K-array™ PAT® technology (Pure Array Technology). 

The column is composed by 3 8x2" interchangeable array modules with an alternating horizontal inclination of each driver, which gives GP18 a 140° wide horizontal dispersion angle for an incredibly immersive sound stage.

Designed for low eye impact outdoor/indoor applications both for rental and permanent installations for public events, live bands, auditoriums, bars and clubs.

Perfect companion of GP18A to create a stereo system or driven by GA43 and GA46 amplifiers.

User Tip: optimize the cost and combine the system with the passive model whether it is for stereo configurations or distributed sound.
