Krix Cyclonix 12 Active Compact Subwoofer

High-Performance 12-Inch Active Home Cinema Subwoofer

The Krix Cyclonix 12 Active Compact is a high-performance active subwoofer designed to deliver powerful, deep and controlled bass for dedicated home cinemas and premium entertainment spaces.

Featuring a 305 mm (12-inch) long-throw woofer, high-efficiency 400-watt RMS amplifier and bass-reflex enclosure with dual down-firing vents, the Cyclonix 12 Active Compact delivers the scale and impact required for demanding movie soundtracks while maintaining a relatively compact cabinet.

With an in-room frequency response extending down to 15 Hz and maximum output of 125 dB SPL, it is engineered to reproduce deep cinematic effects with authority while offering flexible placement behind screens, within cabinetry or in-room.

Powerful 12-Inch Long-Throw Driver

At the heart of the Cyclonix 12 Active Compact is a nominal 305 mm (12-inch) paper cone driver equipped with a 50 mm (2-inch) long-throw voice coil.

The driver has been developed specifically for high-output, low-frequency reinforcement, allowing the subwoofer to reproduce the deep bass effects and dynamic impact required by modern cinema soundtracks.

400-Watt RMS Active Amplification

The Cyclonix 12 Active Compact features an integrated 400 W RMS amplifier, eliminating the need for a separate external subwoofer amplifier.

Its active architecture allows the amplifier and driver to work as an integrated system, providing the power required to reach a specified maximum in-room output of 125 dB SPL.

Deep 15 Hz In-Room Bass Response

With a specified 15 Hz–200 Hz in-room frequency response, the Cyclonix 12 Active Compact reaches well into the deep-bass region required for cinematic effects.

This extended low-frequency capability helps reproduce explosions, atmospheric effects, musical scores and other demanding soundtrack content with greater weight and scale.

Bass-Reflex Cabinet with Dual Down-Firing Vents

The enclosure uses a bass-reflex configuration with dual down-firing vents.

This design works with the long-throw 12-inch woofer to extend low-frequency output while maintaining the high output capability expected from a dedicated cinema subwoofer.

The down-firing port arrangement also supports flexible placement within home cinema installations.

Designed for Flexible Cinema Installation

The Cyclonix 12 Active Compact is designed for installations where powerful bass must be balanced with practical placement.

Krix recommends it for applications including:

• Behind acoustically transparent cinema screens

• Dedicated home theatre rooms

• Corners and room boundaries

• Custom cabinetry

• Multi-purpose media rooms

• Open-plan entertainment spaces

Its relatively shallow cabinet depth makes it particularly useful where a conventional deep subwoofer enclosure may be difficult to accommodate.

Automatic Signal-Sensing Power

For convenient everyday operation, the Cyclonix 12 Active Compact incorporates signal-sensing power control.

When no input signal is detected, the amplifier automatically switches to standby after approximately 15 minutes, reducing unnecessary power use when the system is not operating.

Optional Wireless Receiver Support

A built-in USB-C 5 V / 1 A connection is provided to power an optional wireless receiver.

This can make installation more flexible where running conventional signal cabling to the subwoofer position is difficult or undesirable.

Australian Designed & Manufactured

Krix has engineered and manufactured loudspeakers in Australia since 1974, and the Cyclonix 12 Active Compact continues that focus on purpose-designed home cinema audio products.

Its combination of high output, deep extension and installation flexibility makes it particularly suitable for serious home cinema systems requiring substantial bass without an excessively deep cabinet.
