GXR-18S

Multipurpose powered subwoofer

High output, self powered (class D switch mode power supply with PFC), direct radiation subwoofer cabinet.

The GXR-18S model is a self-powered subwoofer enclosure specially designed to reinforce the low frequencies of the full range models of the GXR series. You do not need to carry an external amplification rack and it is an excellent option for subwoofer reinforcement in general.

The enclosure has 1400 W class D amplifier switching power supply, with DSP processor. This system can be controlled online in real time and stands out for its high performance, with an excellent power-size ratio.

For portable applications, a wheel kit is available to facilitate transportation. It can also be covered with a practical nylon sheath that protects the box during transport and storage.

Perfectly suited for:

Theatres & auditoriums
Houses of worship
Small / middle sized clubs & discos
Smaller live stages / events
Front fill / side fill reinforcement
Portable sound reinforcement
