Compact Yet Powerful

The CT118S is designed to add low-bass support to the ConTour Series™ full-range cabinets as well as functioning as a stand-alone unit. The compact yet powerful design of the CT118S makes it ideal for a range of different live and audio applications. With its lightweight design and combination options, this subwoofer is perfect for use on the road, combining the durable, rugged construct with powerful low-end bass response. This subwoofer can be used individually or stacked with other CT118 subs to provide even more power for bigger rigs.

Durable Design

With live equipment such as PA speakers, it is essential that the units are durable and well constructed as they will have to endure the bumps and scrapes associated with transporting and setting up the speakers. The CT118S combats this with its Birch Plywood cabinet that provides the housing for the subwoofer. The Birch plywood construct helps to reinforce the housing, helping it withstand any wear and tear encountered in live situations. Finished with a polyurethane lacquer, the CT118S also comes with a metal grille and acoustic foam to prevent damage to the driver itself. The convenient ergonomic handles are ideal for transporting and carrying your subwoofer with ease.

ConTour Series

The CT112S is part of the ConTour Series™ from HK Audio. The ConTour Series™ is comprised of a range of high-performance loudspeaker cabinets for professional nearfield sound reinforcement. Developed to deliver premium quality audio, the ConTour series is ideal wherever high sound-pressure levels, and punch are required in short and medium sized performance areas.
