Large Active Subwoofer HK CTA 118 Hire

A powerful active subwoofer, 18" speaker delivering a precise and powerful 1000 watts RMS via one of its inbuilt amps. The other 1000 watt RMS inbuilt amp is configured and drives either a CTA 208 unit or contour series CT 108, CT 112 or CT 115 mid/high box.
For some this is the bees knees at live events. Packing a powerful punch with all of the required circuitry on-board, including a 56-bit DDO-Pro digital controller, it can deliver well defined bass response and renders impulses with great accuracy with even the heaviest loads. This large subwoofer hire is ideal for your medium to large event with exceptional results indoor and in large spaces outdoors. This large sub rental serves as the rest of the system's engine and is used best when paired with either the CTA 208 mid/high speaker cab or the CT 112 full range speaker.
