Expanding the Performance of the Kii Three

The BXT is not simply a bass extension module. It is a comprehensive performance upgrade that significantly expands the capabilities of the Kii Three while preserving its exceptional imaging, tonal balance, and cardioid behaviour.

Each BXT module adds sixteen additional drivers, dramatically increasing acoustic output, low-frequency authority, and dynamic range while maintaining the precise DSP-controlled performance that defines the Kii ecosystem. ⤵️

Full-Range Extension Down to 20Hz

Low-frequency accuracy remains one of the most challenging aspects of loudspeaker design. The Kii Three BXT addresses this challenge through its sophisticated multi-driver architecture and advanced DSP integration.

The result is frequency extension down to 20Hz with exceptional control and precision. Engineers can confidently monitor the deepest low-frequency content while maintaining clarity and definition throughout the entire spectrum.

Cardioid Performance at a New Scale

A key advantage of the BXT system is its ability to preserve Kii’s renowned cardioid behaviour even while dramatically extending low-frequency performance.

This controlled directivity helps minimise room interaction and boundary effects, providing a more consistent and accurate listening experience than traditional full-range loudspeaker systems. The result is tighter bass, improved imaging, and greater mix translation.

Increased Headroom for Critical Applications

The addition of sixteen extra drivers per system not only extends bass response but also significantly increases available headroom and dynamic capability.

Whether monitoring large orchestral recordings, immersive Atmos productions, modern electronic music, or high-resolution mastering projects, the BXT delivers effortless performance without strain, compression, or loss of detail.

A Floor-Standing Reference System

Visually striking and sonically impressive, the Kii Three BXT transforms the compact Kii Three into a true floor-standing reference monitor.

The combination of exceptional low-frequency extension, controlled directivity, advanced DSP processing, and extraordinary dynamic performance creates a monitoring environment capable of revealing every nuance within a recording. ⤵️

The Ultimate Kii Monitoring Experience

For those seeking the highest level of monitoring performance available within the Kii ecosystem, the Kii Three BXT represents the pinnacle of the company’s engineering achievements.

By combining the precision of the Kii Three with expanded scale, deeper extension, and greater headroom, the BXT delivers a world-class monitoring solution for the most demanding professional and audiophile applications.
