Cyclonix Active


Incredibly efficient for maximum output

18″ driver with extra-long excursion

Exclusive Krix digital sub amplifier (KDSA)

Experience bass like never before. With an internal amplifier to drive the high excursion woofer, you can plug in, sit back and enjoy the bass experience.


The Cylonix Active is the ultimate subwoofer for recreating the lowest possible audible frequencies in your dedicated home cinema.

With a built-in ICEpower® class D amplifier, the Cylonix Active uses a high excursion bass driver mounted in a high quality MDF enclosure featuring the proprietary Krix ‘X’ brace system to eliminate panel resonances.

The giant 455mm bass driver features a 100mm voice coil, powerful vented magnetic circuit and double spider assembly. The optimum cooling system provides fast heat exchange and reduced thermal power compression. The built-in ICEpower® class D amplifier also delivers 450 watts RMS.

The dual front-vented enclosure is tuned to achieve maximum output, resulting in an incredibly efficient subwoofer for high drive level applications, while the front mounted control panel with LED display allows for easy adjustment and use. The unit also includes proprietary Krix rubber feet for improved acoustic isolation on hard and soft floor surfaces.

For the ultimate cinema experience at home, play it through Krix.
