The Secret of Big Speakers
Kii’s mission for the THREE was to break the sonic mould of compact speakers. Powerful small speakers with deep bass have been around for a while now but none so far sounded like a big speaker. The THREE is built to fix that.

Basic acoustics tells us that a classic box speaker only directs sound towards the listeners from the midrange up while bass frequencies are radiated all around. The frequency where this change happens depends on the size of the box front (the “baffle”). The smaller the baffle, the higher the frequency at which bass is still radiated all around instead of directed towards the listener.

That in short is why big speakers have so far delivered much more precise timing and detail in the bass and low mids than small speakers: the room gets less chance to interfere. And that is what Kii has now managed to make a compact speaker do.

Category Killer
The THREE is the first compact speaker that exceeds the clarity of a full size sound system in a large room while its small size means it’s equally at home in much more modest spaces. In fact, smaller rooms will benefit most from the THREE’s controlled bass. Better than big speakers at sounding big and better adapted for small rooms than other small speakers, THREE is a truly no-compromise product.

The Active Wave Focusing Solution
A loop hole in acoustics says that small directive speakers are possible - if you have enough drivers and you feed them the exact right signal. The THREE has a total of 6 (six) ways, front, side and rear, working together to throw the sound in one direction only without relying on a baffle. The THREE’s ability to direct bass is comparable to, but much better controlled than that of a traditional speaker several meters wide.

KII Three Active Wave Focusing Solution

What do Active Wave Focusing filters do?
Active Wave Focusing filters mark a complete departure from the classical crossover filter. Instead of just splitting the spectrum into bands, it forces the specially positioned drive units to create a completely coherent wave front that is only emitted forward and behaves as though all of it came from the mid-range driver.

With classical crossover filters, loudspeakers can only have a time aligned impulse response on the main axis. The animations on the left show the wave front as it’s built up by a typical modern three-way speaker with side-firing woofers. This example is crossed over at 250Hz, time aligned and phase equalized. Indeed the wave travelling towards the listener is coherent. Towards the sides and the rear the picture breaks down and the impulse is completely smeared. Also, low frequencies get emitted in all directions. In a real room (bottom animation) the sound that escapes toward the back will strike the wall behind the speaker and reflect towards the listener, who actually hears the speaker twice: once from the front and a bit later from the rear. Moving the speaker out into the room doesn't help. The overall bass balance looks better but the impulse response gets worse as the reflection now comes even later.

The animations on the right show how the Active Wave Focusing method retains full time alignment all around the speaker and how the presence of the rear wall has no impact. Sonically, the effect is a very even, unusually detailed bass. Even in problematic rooms, a drum kick has that visceral thud that previously only very big or in-wall speakers could achieve.

The Kii Lifestyle
Hidden behind the beauty of the Kii THREE is an amazing 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!

Not only do we use current technology to build a modern active speaker system, but we advance technology from the ground up where necessary and we employ it in ways no one has done before. What may appear to be a cute pair of speakers at first sight, is really a powerful audiophile system that effortlessly outperforms all others, regardless of price.

The clarity and detail, the impressive time coherence and most importantly the handling of the room acoustics let the listener dive right into the magical experience of a great record, more so than even the best conventional (passive) setups are able to. All the innovations inside this speaker serve one single purpose: to be more truthful 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 Kii THREE HiFi Stands
perfectly designed to go with the Kii THREE is the Kii THREE stand.
The stands are made out of high quality steel and are powdercoated in black RAL 9005.
The tubes are sand fillable to eliminate eventual resonances and vibrations.
They are 27,5 Inches tall to fit the perfect home listening height and come with M8 spikes.
To ensure a stable sit, the top plate is a perfect fit for the retracted bottom plate
of the Kii THREE.

The Kii THREE colors
The Kii THREE comes in two standard color schemes from 2017 on. High Gloss White and Graphite Satin Metallic.
Any custom color can be ordered at a surcharge. To perfectly fit the Kii THREE into your living room, you can choose any color that suits your taste. You have a choice of finish between high gloss, matt or metallic. The brushed aluminum covers always stay the same color. They are anodized in black to match the stands.

Kii Technology
Each Kii THREE contains six channels of DSP, D/A conversion and power amplification. Few companies could pull off such a densely packed design with truly world class performance electronics. But then again, few active speakers are designed by people who have previously turned high end power amplification and digital conversion around.

Each side panel of the THREE holds a 3x250W power amplifier board, designed by Bruno Putzeys using the latest iteration of the Ncore class D technology which he invented for Hypex. Unique to the implementation used in the Kii THREE is a combined voltage/current control loop that goes beyond merely a better amp – it actively improves the distortion performance of the drive units which contributes significantly to the extreme resolution of the speaker.

Naturally, this means that the performance of the AD/DA conversion has to match that of the amps. This task fell to Bart van der Laan who has a long track record designing DSP and converter boards for high-end professional audio equipment. Kii Audio’s implementation is a runaway success: a complete pass through the AD/DA circuitry of the THREE’s signal processing board is entirely inaudible, a feat not duplicated by the most expensive audiophile standalone units.

Alongside the Active Wave Focusing filters the DSP is responsible for keeping the drive units within their safe operating range by gently adapting the filters instead of brutally limiting the signal, allowing the THREE to play significantly louder and cleaner than much bigger traditional designs.

On the input side there is a choice of analogue, digital inputs. All digital inputs are up-sampled and reclocked using Kii’s own jitter rejection algorithm that guarantees actual “bits is bits” audio performance for any digital source.

The electronics package alone sets a milestone. What it does in concert with the unique acoustic design defies imagination. You have to hear it to realise the magnitude of the revolution the Kii THREE represents.

How close can I place the Kii THREE against the wall?
The Kii THREE can be placed roughly 8-10cm (4 Inches) close to the back wall.The cardioid directivity (if activated) is fully maintained even with this very close proximity to the back wall.

This makes placement very easy and even allows the Kii THREE to be placed on a sideboard in a living room, if there´s no room for a free setup on speaker stands.

On the control panel of the Kii THREE you even find a small dial, where you can choose the appropriate setting for your preferred placement in your room. This setting adjusts the very low frequency range (<40Hz) and makes sure you always have a perfect frequency balance, no matter if your speakers are free standing, close to the back wall or even placed into a corner of the room. 

What is the difference between the HiFi and the PRO Version?
The PRO version comes in a dark grey spatter paint finish that is very rugged, HiFi version in high gloss white or graphite satin metallic. Technically there is no difference.

Which audio formats are supported by the Kii THREE?
The Kii THREE supports analog balanced input and digital formats up to 24bit/192kHz on its AES inputs. The Kii CONTROL offers three additional digital inputs for the Kii THREE: Coax SPDIF, Optical TOSLINK and USB (up to PCM 24/384kHz and DSD64/DSD128 on USB).

What kind of outputs can I connect to the Kii THREE?
ANALOG - The Kii THREE has a balanced analog input on XLR:
a) If your source or preamp has a symmetrical analog output (XLR plug), this is the preferred connection method with a high quality XLR-to-XLR cable.
b) If your source or preamp has a single ended output (RCA/Cinch plug), it can be connected with a simple adapter cable RCA-to-XLR.
DIGITAL - The Kii THREE has a balanced digital input on XLR (AES format):
a) If your source or preamp has a digital AES output, this is the preferred connection method via a digital AES cable (XLR-to-XLR, 110Ohm)
b) If your source or preamp has a digital SPDIF output, it can be connected with a special digital adapter cable to the AES Input on the Kii THREE (RCA-to-XLR, 75Ohm to 110Ohm impedance matching) or straight to the Kii CONTROL.

Do I connect my source analog or digital?
The preferred connection for all digital sources (like CD Drive, CD Player with digital out, Music Streamer, Digital Radio etc.) is the digital input.

If you have a truly analog source like a turntable + phono preamp or a tape machine, please use the analog input on the Kii THREE.

If you like to use the Kii THREE simply as an active speaker in combination with your analog hifi preamp as the source selector and volume control, you can also use the analog input on the Kii THREE.

In reality the performance of the built in A/D converter in the Kii THREE is so outstanding, that you don´t loose any fidelity, if you may want to use your existing preamp with it. If you hear a difference, it´s mainly due to the sound quality of your preamp.

What is low latency mode and when to use it?
Some people might want to use their Kii THREE alongside a TV or Beamer to also enjoy their sound qualities when watching a movie or DVD.In some cases the latency that occurs from the extensive DSP calculations within the speakers may actually be too high to be properly compensated by the available settings on your TV or beamer.

For this case we offer a special low latency mode for the Kii THREE, which changes some of the filters in the DSP and therefore provides an extremely short (nearly neglectable) latency.

The overall sound quality is not as perfect in low latency mode as it is in normal mode (most notably only in the low end), but still provides a very pleasurable listening experience for your TV. Also the ActiveWaveFocusing is still fully intact in low-latency mode, so the speakers keep their cardioid dispersion qualities.

HOW: Switching latency modes on the Kii THREE is done by a short press on the P/R button located on the backside connector panel.

The front LEDs will indicate this by ONE red LED lighting up to indicate low latency mode,or TWO red LEDs lighting up for normal operation mode again after a second short press of the P/R button. For pure audio listening pleasure, please always make sure your Kii THREE is set to „normal mode“.

Here are the latency specs for your reference:
LOW-LATENCY MODE: Analog input (A/D - D/A): 1030us (or 1,03ms)
Digital input (D/A only):
@ 192kHz = 945us (or 0,945ms)
@ 96kHz = 860us (or 0,860ms)
@ 48kHz = 1540us (or 1,540ms)
NORMAL MODE: approximately 90ms
