Cyclonix Series (11 / 12 / 15 / 18 / Megacyclonix)
Krix Cyclonix Series Dedicated Cinema Subwoofers
Krix Cyclonix subwoofer family for dedicated cinema — available in 11", 12", 15", and 18" configurations plus the flagship dual-driver Megacyclonix. Australian-engineered for musical bass extension and cinema-reference dynamics.
Overview
The Krix Cyclonix Series is the dedicated cinema subwoofer range from Australia's longest-established cinema speaker manufacturer. The family spans four standard models — Cyclonix 11, 12, 15, and 18 — representing driver diameters of 11, 12, 15, and 18 inches respectively, plus the flagship Megacyclonix, which houses dual high-excursion drivers for maximum output and infrasonic reach. All Cyclonix models are designed to deliver the deep, authoritative, yet musically accurate bass that cinema soundtracks demand, from the subtle low-frequency textures of orchestral scores to the full-impact dynamics of action and sci-fi content. The larger models (Cyclonix 15, 18, and Megacyclonix) are specifically sized for larger dedicated cinema rooms where reference-level bass extension below 20Hz is required. The Cyclonix range is passive, requiring an external amplifier, giving system designers full control over drive levels and integration with bass management systems. Cabinet construction is robust, with internal bracing and high-excursion drivers matched to the specific enclosure volume of each model.
Pros & Cons
Strengths
- Wide model range covers every room size from compact to ultra-large
- Passive design gives system designers full control over bass management
- Sealed enclosure delivers tight, accurate bass without port coloration
- Megacyclonix provides commercial cinema-grade infrasonic output
- Consistent build quality and sonic character across the entire Cyclonix family
Limitations
- Passive design requires external amplifier channels per subwoofer
- Larger models (15, 18, Megacyclonix) require significant room volume for effective deployment
- No built-in DSP — equalisation and integration must be managed externally

Application
Integrating the Krix Cyclonix Series in a Dedicated Home Cinema
Kolosseum specifies Cyclonix subwoofers as the natural bass complement to Krix dedicated cinema speaker systems. Model selection is driven by room volume, seat count, and target SPL and frequency extension. For the most demanding designs, multiple Cyclonix 15 or 18 units are deployed in a distributed bass array to improve low-frequency uniformity across all listening positions.
Room Requirements
Subwoofer placement in dedicated cinema rooms is a critical acoustic consideration. Kolosseum models low-frequency room modes during the design phase and specifies subwoofer positions that minimise in-room peaks and nulls. Larger Cyclonix models are typically built into dedicated cavities within the room structure for cleaner integration.
Recommended Screen Pairing
Cyclonix subwoofers work alongside all Krix screen channel options — MX Series, Megaphonix, Phonix — and are driven from the LFE and bass management outputs of the cinema processor or AV preamplifier.
Acoustic Considerations
Low-frequency management is one of the most complex aspects of dedicated cinema design. Kolosseum applies acoustic modelling and measurement during commissioning to integrate Cyclonix subwoofers optimally with the room, using processor-side EQ and delay to achieve a smooth, even bass response across all seats.
Frequently Asked Questions About the Krix Cyclonix Series Dedicated Cinema Subwoofers.
Model selection depends primarily on room volume and target output levels. As a general guide: Cyclonix 11 suits smaller rooms up to ~30m³, Cyclonix 12 and 15 for medium to large rooms, and Cyclonix 18 or Megacyclonix for large or demanding high-SPL cinema environments. Kolosseum performs acoustic modelling during the design phase to make precise recommendations.
Yes, and this is often recommended. Running multiple Cyclonix units in a distributed bass array significantly improves low-frequency uniformity across all seating positions, reducing the impact of room modes. Kolosseum commonly specifies two to four Cyclonix units in larger dedicated cinemas.
All Cyclonix models are passive speakers requiring external amplification. Kolosseum specifies high-current mono or stereo amplifiers with appropriate power ratings for the selected model. The amplifier output is controlled via the bass management system of the cinema processor (Trinnov, StormAudio, etc.).
The Megacyclonix is a dual-driver flagship subwoofer that effectively doubles the piston area compared to a single Cyclonix 18, providing greater maximum output and lower frequency extension. It is specified for the largest and most demanding dedicated cinema environments.
