GTA 221 B
Self-powered subwoofer system of high performance, equipped with two (2) speakers of 21″ in a tuned enclosure. GTA 221 B is an excellent low reinforcement for all the systems from the GTA Series. It is the perfect solution for P.A. in outdoor events and permanent installation where it is necessary high performance and SPL. Since it is a subwoofer system, the transducer configuration generates an omnidirectional audio projection.
It is excellent to be combined with GTA 2X12 L.A. or GTA 2X15 L.A. to create different configurations of high performance and SPL.
GTA 221 B incorporates a Class D amplifier module of last generation Pro DG Systems GT 4.0.
DSP Software is available. Consult our Technical Service for more information.
