Description

Product Description

An active, direct-loaded subwoofer, the 18“ CTA 118 SUB serves as the system’s powerful engine room. All the required circuitry is on board, including a 56-bit DDO-Pro™ digital controller and two 1,000-watt RMS PWM power amps. One of the power amps drives the subwoofer’s 18“ speaker; the other is configured by the controller to drive a CTA 208 mid/high unit or a ConTour Series™ CT 108, CT 112 or CT 115 enclosure.
The internal electronic circuitry is shock-mounted on rubber grommets, while a dolly facilitates transport and affords additional protection against damage and dirt.
