Compact Kii Three Speakers With Life-Sized Fidelity
NEWS: Radical Design Breakthrough Endows Compact Kii THREE with Life-Sized Fidelity

Brilliant mix of cutting-edge amplification and DSP delivers the full-frequency dynamics of a large high- end floor stander from a super-discreet active system.

It’s an age-old trade-off. Audiophiles seeking the most intimate contact with music must accept the inconvenience of living with huge speaker systems. The orthodox view is that only big speakers with large baffles can directly deliver more precise timing and detail in the bass and low mid frequencies while mitigating the destructive effect of room reflections on sound quality.

All this changes with the astonishing and beautifully bijou Kii THREE speaker: an innovative and coherent union of discreet DSP, D/A conversion and power amplification channels, individually calibrated for a total of six drivers firing to the front, side and rear, but working together to throw the sound in the forward direction only. In this way, the game-changing Kii THREE system, having the physical dimension (WxHxD) of just 20x40x40cm, is able largely to eliminate the negative impact of the room on low to mid frequencies and reproduce the acoustical scale, timing and dynamics of a large audiophile floor-standing speaker system.

For the first time, in any space and regardless of room position, an aesthetically attractive, space-efficient high-end audio system can offer design-conscious audiophiles liberation from the ‘big is best’ mentality. Using radical engineering, the extraordinary Kii THREE proves that a small speaker really can sound like a big one.

Kii Technology: Active Wave Focusing DSP

Overturning the orthodoxy governing the interaction of drive systems with rooms, Kii THREE system deploys
proprietary Active Wave Focusing filters, which allow specially positioned drive units (a front-firing 1" wave- guided tweeter and 5" midrange, 2 x side-firing  and 2 x rear-firing 6.5" woofers) to create a completely coherent time-aligned wave front that is only emitted forward and behaves as
though it came from the midrange driver. The ingenious DSP operates like a directional cardioid microphone in reverse, eliminating all
backward radiation from the driver system. It is also responsible for keeping the drive units within their safe operating range by gently adjusting the AWF filters, allowing the THREE to play significantly louder and cleaner than much bigger traditional designs.

Kii Technology: Driver-Dedicated Ncore Power Amplification

Designed in sympathy with the DSP, amplification comprises no fewer than 6 x 250W Ncore power amplifiers (one for each driver) arranged on twin three-channel boards installed in the side panels of the Kii THREE. For this implementation Bruno Putzeys’ acclaimed Ncore class D technology has been especially enhanced with a combined voltage/current control loop, which actively improves the distortion performance of the individual drive units, contributing significantly to the extreme resolution of the system.
Kii THREE inputs and settings.

There is an XLR input (selectable analogue L/R or AES/EBU digital audio signals). All digital inputs are up-sampled and re-clocked using Kii’s own jitter rejection algorithm that guarantees actual “bits is bits” audio performance for any digital source.
The connector panel also features twin Kiilink RJ45 input/outputs (CAT cable included) for connecting other Kii products or the ‘Slave’ Kii THREE when the stereo digiial AES/EBU is used.

A sixteen position (free / wall / corner) Boundary switch allows the Kii THREE’s DSP to compensate for room positioning and a ‘Contour’ control selects from fourteen preset EQ curves (+ flat-position) to fine-tune the system’s linear frequency response according to personal taste.


The ultra-compact Kii CONTROL preamp/USB Interface allows a Kii THREE pair to perform as a complete audiophile playback system combining touch-control of input selection, lossless volume control, power, finer EQ calibration and preset memories with the facility for a further three digital inputs: Coax SPDIF, Optical TOSLINK and USB (up to PCM 24/384kHz and DSD64/DSD128 on USB).

The Kii Control connects (and is powered) through a single CAT cable (included) and menu navigation is aided by an integrated OLED display.  Alternatively, the main Kii THREE system functions such as volume, source and mute can be remote controlled via IR Remote (RC5 type or Apple Remote).

The Kii THREE Stands

At 70 cm tall and of RAL-9005 black powder-coated high quality steel, the Kii THREE custom stands are sand-fillable to eliminate resonances and vibrations. For the perfect aesthetic outcome the stand’s supporting top plate matches the contour of the Kii THREE.

The Kii THREE colours

The Kii THREE is available in two standard colour schemes: High Gloss White and Graphite Satin Metallic. Absolutely any custom colour in a choice of high gloss, matt or metallic finishes can be ordered at a relatively small surcharge. The brushed aluminium driver panels are anodized in RAL-9005 black to match the stands.
