The CS Series is built for working audio teams that need dependable low end without a heavy rig. Corporate AV crews, houses of worship, DJs, mobile production companies, and small venue installers can pair it with compact tops for fixed rooms, rentals, and one-off events. It is offered in 15-inch and 18-inch driver versions, so you can match output and extension to the room, the program material, and the truck space you have available.

Powered operation removes the need for a separate amplifier rack, and a universal power supply makes the same unit practical across venues in different regions. A tech can dial in the system, then fine-tune it from the room instead of walking back to the stage. Running two or more units opens up directional low-frequency control for stages and rooms where bass buildup is a problem.

Compared with passive subs that need external amplification and processing, the CS Series keeps the signal chain short, which means fewer cases, fewer cables, and faster load-in and teardown. Choose the smaller version for tight rooms and portable rigs, or the larger version when the program calls for more low-frequency extension.
