The Kii Three brings an exhilarating and transformative audio experience, delivering unparalleled clarity, deep and resonant bass, and a liveliness that fills the room, enchanting every listener!
The Kii THREE proves that breathtaking, full-scale sound doesn’t require towering floorstanders or a wall of electronics. In a footprint barely 20 cm wide, it hides a fully active, six-way system capable of delivering clarity so vivid and bass so deep (down to 20 Hz) that your favorite tracks feel brand new again. Whether positioned free-standing, near a wall, or even in a corner, it adapts effortlessly to your room thanks to its cardioid dispersion and boundary EQ. With its built-in amplification, DAC, and DSP, it’s an all-in-one high-end system — no extra gear needed beyond your source. From quiet evenings to party-level playback, it delivers ultra-low distortion and tonal consistency at any volume, making every moment with music unforgettable.
Six precision drivers, each with its own 250-watt Class D amplifier, are directed by a powerful 40-bit DSP. This not only shapes a cardioid dispersion pattern from 40 Hz upwards but also time-aligns every driver for perfect phase coherence, ensuring all frequencies arrive as a single, unified wavefront. The result is a holographic soundstage, precise imaging, and the ability to place the THREE almost anywhere without compromising performance.
Enjoy your favorite playlists with zero fuss, stream high-res tracks via the optional Kii Control, or connect a turntable for analog warmth. And when you’re ready to go bigger, the Kii THREE is fully upgradeable — add the BXT module to unlock a full-range, floorstanding experience without increasing footprint.

The Kii CONTROL turns the Kii THREE into a complete playback system of highest sonic quality and usability. It offers a user interface for your speakers and works like a digital preamplifier.
Only connect your analog source, CD player/drive, server, streamer, TV set or set top box to enjoy a breathtakingly audiophile full range system in a stunningly small footprint.
The Kii CONTROL offers three additional digital inputs for the Kii THREE: Coax SPDIF, Optical TOSLINK and USB (up to LPCM 24/384kHz or DSD64/128 on USB).
All inputs are located on the backside connector panel and can be activated with the touch buttons located around the volume knob. A dedicated input button (labeled XLR) will switch to the existing hardware input on the speaker itself, which you can continue to use as analog or digital input. The Kii Control connects with a single included CAT6 cable and is also powered through this connection. No additional power supply is necessary. Most importantly the Kii CONTROL enables lossless volume control inside the DSP of the Kii THREEs, keeping the signal path of the system as transparent as possible. The big volume knob also offers mute or dim functions and manual power on/off (standby). A dedicated touch button provides direct access to up to six user definable presets. The menu navigation and OLED display vastly expand the options of the Boundary and Contour settings, while also providing access to more advanced system settings, including amongst others for example manual power on/standby, LED brightness, DIM function and limiter indication. The main functions like volume, source and mute can be remote controlled via your IR Remote (RC5 type or Apple Remote).
Only connect your analog source, CD player/drive, server, streamer, TV set or set top box to enjoy a breathtakingly audiophile full range system in a stunningly small footprint.
The Kii CONTROL offers three additional digital inputs for the Kii THREE: Coax SPDIF, Optical TOSLINK and USB (up to LPCM 24/384kHz or DSD64/128 on USB).

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.
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 packs 1500 watts of Class D amplification across six drivers (front, side, and back), achieving a level of performance and detail often associated with much larger systems.
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.

Bluetooth is a wireless communication protocol that allows to stream music directly from mobile devices like phones or tablets.
Hi-Res Audio, short for High-Resolution Audio, refers to digital audio formats and equipment that provide higher sound quality and fidelity than standard audio formats like MP3 or CD audio. Hi-Res Audio aims to reproduce audio with greater precision, capturing more detail and nuances from the original recording, resulting in a more immersive and lifelike listening experience.
“Roon Tested” is a designation Roon Labs gives audio devices verified to work well with Roon software. Unlike “Roon Ready” devices, which are typically network-enabled and can directly interface with Roon’s core server, “Roon Tested” devices may not have network capabilities but have been tested to ensure they perform optimally when connected to a Roon system, typically through USB, HDMI, AirPlay, Google Cast, or other connections.

Most loudspeakers are an evolution of those that have come before, a refinement of existing technologies. The fully active Kii Three turns that notion on its head by using DSP (digital signal processing) in such a radical way that the resolution it delivers is frankly outrageous. By cancelling rearward bass output the Kii Three reduces the impact of the biggest problem faced by loudspeakers, the room.
This is the most revealing loudspeaker I have heard for a long time and yet it’s not the size of a house and nor does it cost a fortune by high end standards. It just shows that a cleverly designed active loudspeaker has a significant advantage over the majority of the competition. Jason Kennedy
Qobuz Connect is known for its high-quality music streaming, including support for lossless and Hi-Res Audio. The software enhances the listening experience by allowing users to stream music to compatible audio devices and speakers easily.
