The Kii THREE redefines the standard for compact speakers by delivering the full-bodied sound typically associated with larger speakers in a small package. This speaker offers an exhilarating audio experience with unparalleled clarity, deep and resonant bass, and lively sound that fills any room. Ideal for live music enthusiasts, the Kii THREE promises to transform your musical journey.

The Kii THREE's innovative approach to acoustics sets it apart. Unlike traditional box speakers that disperse lower frequencies in all directions, the Kii THREE's compact design ensures that even the bass and low mids are directed toward the listener. This results in clarity and detail previously only achievable with larger speakers, now available in a more compact form.

Exquisite Sound Engineering

The Kii THREE boasts a range of advanced technical features. Four 6.5" woofers deliver deep, resonant bass, while the 5" midrange provides exceptional clarity. The 1" waveguided tweeter captures the subtlest nuances in the music. With 1500 Watts of power per speaker, the Kii THREE fills any room with dynamic, robust sound. Its Line Source Cardioid Dispersion technology directs sound precisely to the listener and minimizes room reflections, resulting in a pure, immersive listening experience. The Kii THREE turns your living space into a concert hall, offering an intimate and lively performance.

Features

  • Custom Waveguided Tweeter: Enhances tweeter efficiency, controls directivity, and boosts performance.
  • 5'' Midrange: Delivers smooth frequency response, lifelike vocals, and engaging instrumentals.
  • Cardioid Dispersion: Minimizes the negative influence of room acoustics by directing sound effectively.
  • Four 6.5-inch Woofers: Provide robust bass and unrivaled directionality for a transformative audio experience.
  • Built-in Amplification: 1500 Watts per speaker ensure incredible clarity, detail, and tonal balance.
  • Wave Focusing Crossover Filter: Synchronized drivers deliver unparalleled sonic clarity and precision.

Kii CONTROL

The Kii CONTROL enhances your Kii THREE system with a digital preamp and USB interface, offering lossless volume control. It integrates seamlessly with CD players, servers, and TVs, adding three digital inputs: Coax SPDIF, Optical TOSLINK, and USB. Supporting resolutions up to LPCM 24/384kHz or DSD64/128 on USB, it ensures high-quality audio.

With user-friendly inputs, touch buttons, and an OLED display menu, the Kii CONTROL allows easy operation and system customization. It offers volume, mute, dim functions, manual power options, and up to six presets. An IR Remote provides convenient remote control for volume and source selection.

XLR Connectivity 

The XLR connector is crucial for balanced audio transmission, minimizing interference and noise, especially over long distances. Widely used in professional audio environments, XLR connectors ensure reliable, high-fidelity sound. They also support AES/EBU digital audio signals, maintaining signal integrity for both analog and digital audio reproduction.

BXT System Upgrade

The THREE BXT system is a studio-grade full-range reference that brings main-monitor scale to any space — without sacrificing precision. Sixteen additional woofers form a vertical line array that shapes and controls the low end, focusing energy where it counts and minimizing floor and ceiling reflections. With over 7,000 watts per stereo pair, you get massive headroom, unshakable control, and the authority to work confidently on any project.

Advanced Control for the Critical Low End

The BXT integrates seamlessly with the THREE, sharing the same DSP brain for perfect time alignment and phase coherence. The cardioid dispersion from the THREE combines with the BXT’s line array effect to deliver bass that’s as accurate as it is powerful, even in challenging acoustic environments.

For Projects That Deserve the Best

From mastering orchestral recordings to producing bass-driven electronic tracks, the THREE/BXT gives you a full-bandwidth, high-SPL monitoring solution with zero compromise on detail or accuracy. It’s the clarity and control you need to make decisions fast — and know they’ll hold up anywhere.

At Home In Any Room

Hidden behind the beauty of the Kii THREE is a fantastic speaker that is small enough to fit easily into modern living spaces. It doesn’t take over your habitat like a huge old audiophile setup; there are no racks, no big towers, no cables to trip over. Instead, there’s intelligence! The clarity and detail, the impressive time coherence, and, most importantly, the handling of room acoustics let the listener dive right into the magical experience of an excellent record, more so than even the best conventional setups can.

All the innovations inside this speaker serve a single purpose: to be more true to the music. Kii brings more music into your life. Let’s face it: buying a second system for daily use because the “big” system is too impractical for background listening was never a solution. Even the best Hi-Fi set should be easy and intuitive to use for anyone in the house. Whenever there’s music on your mind, there should be great music in your home.

The BXT is an extension module that turns the Kii THREE into a veritable floor-standing loudspeaker with 16 additional drivers. The Kii THREE BXT System is absolutely unique as it combines a line source with horizontal directivity control! The BXT makes full use of the Kii THREEs technology, adding a wider frequency range and increased SPL to the game while still being a cardioid system that, despite its size, does not interact with the room. Astoundingly enough, small rooms benefit significantly from the line source concept.

What Makes Kii Audio Truly Unique

Founded in 2015 by acclaimed audio engineer Bruno Putzeys, Kii Audio has quickly become renowned for tackling long-standing challenges in speaker design. At its core lies a revolutionary Active Wave Focusing technology, which employs DSP-driven cardioid dispersion. This innovation allows compact speakers, like the Kii SEVEN, to deliver sound with grand-system clarity while minimizing unwanted room reflections—dramatically enhancing timing, bass precision, and spatial fidelity. What’s more, each Kii THREE BXT packs 3500 watts of Class D amplification across fourteen drivers (front, side, and back), achieving a level of performance and detail often associated with much larger systems.

Disruption and Decades-Long Innovation

Kii Audio is widely seen as a disruptive force in a traditionally conservative audio market. As noted by What Hi‑Fi?, “True innovation seems to be a rare quality in speaker design… But not at Kii.” Their approach not only overcomes typical acoustic compromises but also introduces entirely new paradigms for directivity and listener experience. With a steadfast commitment since 2015 to advancing both hardware and software—encompassing compact cardioid speakers and the newly unveiled Kii Seven wireless music system, complete with multi‑room smart control—the company demonstrates a decade‑long dedication to innovation and pushing boundaries.

Between their bold engineering breakthroughs, professional-grade performance in a refined form, and long-term devotion to innovation, Kii Audio stands out as a genuinely transformative presence in the audio landscape.
