Key info

Clean lines, clean bass
A high sensitivity 6″ 4th order bandpass subwoofer, cS6 is designed to be installed into your ceiling, with only a small port opening, allowing all the bass to fill your room for maximum impact, but with nearly zero visual impact.


Ported Perfection
With a selection of 3 various port locations on the cabinet, it is possible to position the subwoofer in nearly all ceiling cavities, porting freely into the room below. Simply select which port position of the three will work best for your space, allowing correct orientation of the cabinet.
Not only is the position of the port adjustable, but it can also extend by up to 110mm from the front of the cabinet, allowing the port tube to line up perfectly with your ceiling. This helps to deliver bass seamlessly into your room, and not into the ceiling.


Secure, Simple, Strong
Using the supplied L-brackets, cS6 is attached directly to the wooden joists or framework prior to installation of the ceiling board. Adjusting the port length to line up with the finished ceiling level and pre-cutting the port opening in the ceiling board makes for a fast and seamless installation to deliver strong bass in a secure and safe manner for years to come.


Powered by standard audio amplifiers. Can be used as part of a surround sound system (subwoofer output from AVR into a separate amplifier) or as part of a multi-room music system for big bass. On-board analogue filtering means that most standard power amps are suitable.
