Kii Audio Three Test: Close to Perfection

Newcomer has developed a fully digital active speaker system with its three Kii audio that will make the boxing scene on its head. The pleasantly compact furniture boasts unique authenticity and is on top of that enormously adaptable.

  2. Kii audio three: functions, optics and conclusion

Drives with enhanced signal fidelity and more precise crossover yield from time to time minor improvements at the sound of the speakers, but the big breakthrough occurred in the last few years. Also the reluctance of many users against Active concepts with built-in amplifiers and electronic filters is because not uninvolved, although their superiority has been known for years and we Tester on every appropriate occasion to point out.

No motor vehicle specialist came up with the idea to run an engine for city vehicles in a truck, but such rational not always comprehensible combinations are widely used in the HiFi scene. Not infrequently amplifier and speakers are coupled, true to the motto “The journey is the reward” simply at your whim.

This poking around in the fog could come now out of fashion, because with the compact three Kii audio, an active speaker novel in many ways takes the stage. Their amplifier branches are precisely matched to the driver. The DSP-controlled crossover networks produce a unique time and frequency linearity, with selected drivers hard on the border of what is physically feasible. On top of that, the theme of room acoustics, highly effective gone.

So much had previously betrayed: the living room-friendly Kii three achieved the best test result in a compact box in the audiophile important areas in more than 30 years of AUDIO history and outclassed effortlessly far more expensive speakers amplifier combinations. But before we wallow in superlatives, it is important to shine through concept and technology.

Kii audio is a merger of five enthusiasts with many years of experience in Studio technology and high end scene. Mastermind of the 2014 based company based in the Westphalian Wermelskirchen is none other than Bruno Putzeys, who is responsible at the Dutch amplifier and filter specialists Hypex for numerous based developments. Eventually the concept of the LS 1 of Grimm came from his pen audio that 5/2013 had left a great impression at the test in the issue.

Amplifier module of the latest generation, which for the first time have a kind of impedance feedback into the three. The highly energy-efficient and space-frugal modules learn as an adaptation to the specific weight of the driver and their frequency range.

Six chassis and as many units of amplifier with power output of 250 Watts each into the three. Like any decent active speaker, the three in the bass is electronically equalised, i.e. transient response and lower cut-off frequency are determined by programming the filter less by the sparse volume of housing and the Thiele-Small parameters of the chassis. This performance is increasingly fed the drivers with declining frequency and so the property-related sound pressure compensated.

Compared to a not corrected box the power demand in the bass easily increased by factor ten also because was dispensed with in the three in the interests of maximum sound precision efficiency-promoting reflex tubes. Four extremely hub strong bass drivers deliver the necessary diaphragm. Two sit side to side, two back. The data sheet promises 20 hertz without losses, but according to the measurements (see last page) the lower cut-off frequency is even at 19 Hz. The Kii alone with its frequency bandwidth can be the most passive speakers look old even larger Floorstanding speaker.

But it gets better: the DSP control operates the bass chassis as also the midrange driver in two areas, resulting in solid angle-dependent level subsidence. While ordinary boxes directed emit only MIDs and highs, bass and keynote range but mostly spherical in shape, made the three a directional effect until about 40 Hertz down. In the virtual view from the top is a kidney with a distinctive sound pressure minimum behind the boxes from the usual pie chart.

The targeted coverage at large wavelengths is a long awaited stroke of genius, because so the sound even at low frequencies is mainly from the box determined and hardly any of the space and its various modes. Overly stressed and fuzzy bass are old news.

Bass quantity and angle behavior can be varied via a Rotary. The maximum setting is intended for free-field-like conditions (large rooms and distant wall boxes position) and leads to the pictured in the measuring laboratory box, straight frequency response. The minimum setting is intended to be corners of the room, where three sound-hard surfaces in the game are the same. The adaptation takes place in 16 fine levels, so mixed forms are covered.

This technique can be adapted to the three to almost any environment and sounds ideally always equally neutral and accurate. A placement near a wall has no disadvantages and acts on the contrary even Dynamics promoting, because drivers and amplifiers must expend less energy. It cannot be even closely, because the recommended minimum distance between bass and wall is only eight centimeters.

Ordinary place filter in conventional boxes reduce the bass level for all solid angle and combat only the symptoms with acoustically-induced on coverts, because the area beside and behind the box be only less excited, but not effectively hidden. The three packs this highfidele default problem at its roots, because the critical zones are stimulated only not great. The bass range by no means thinner sounds through the kidney but worlds precise.

Some of CIIS philosophy is striving for a perfect timing. A slight delay of the medium frequency unit levelled the mechanical misalignment between the drivers and can happen at the same time the listener despite complex filtering all frequencies. An exact step response as an indication of the time accuracy manages only the fewest three-way speakers, but the Kii completed also this exam with flying colors.

Because maximum neutrality has not always been, there an also sixteen-stage “taste button” with various frequency gear gadgets in addition to space adaptation.

The startup of renowned manufacturers refers to the six drivers. The well 16 centimeter woofer work, as also the slightly smaller midrange driver with high fixed cones. A flush-approved canopy system is responsible for the heights. Smaller series variation are equalised at each box on the DSP.

The only 20 cm wide plastic housing consists of two half shells poured out of sound-neutral plastic which are often stiffened. Standard color is white in combination with dark gray shutters. For an additional fee, the color is selectable, so boundless imagination.

It is controlled via XLR and preferably digital with up to 24 bit / 192 kHz. After flipping a small switch, analog signals are received. There are two controllers are added in the not-too-distant future. The small solution, which already appears in the coming year, sees itself with USB or S/PDIF, offers only a volume control. The ‘great’ controller intended for later should offer more inputs and communicate wirelessly with the three. But basically a laptop goes with a popular audio player.

We could make do with the three with the shortest description of sound ever, because their high-precision essence grabs one immediately and let go of any more. And you can feel within seconds, what differentiates the three from conventional boxes-amplifier combinations.

You sounds glockenrein, spatially as dynamically exactly on the point and seems likely to consign alone with their terrific authenticity that some prospective buyer at the dealer gives his Yes Word faster as it can serve the mandatory consultation coffee.

Ultimately, it was but a long evening, although the judgment at an early stage it was clear: we hear differences such as with any other boxes amplifier combination with this exception of transducers and enjoys a sound accuracy, which also mercilessly exposes recording weaknesses as it deepened moments of happiness.

The sound character appeared as varied as full-bodied and corporeal, room exactly appeared in all three dimensions and was blessed with an incredibly lifelike bass on top. Such transparent and assertive way up in the very lowest layers still no box has played in the AUDIO listening room. The three had a quantitatively by no means shy of all precision. Even free-standing, more than a meter of all walls away, it seemed advisable to take the bass over the place filter one or two steps back.

The acoustic duo friend ‘n fellow has newly recorded the Lou Reed classic “Walk On The Wild Side” in 2010. With the CII audio three sound the song almost extraterrestrial easily and relaxed. And he gave a variety of tone color, where we don’t enough want hear us. Wild times are likely to crack for the competitors of Kii audio, because similarly ingenious concepts are far and wide is not in sight.

Conclusion

With the three several long-held wishes come true. The sound pressure reserves are more than adequate despite the pleasantly compact form. The ability to adapt space and the enormous potential of deep bass can look familiar concepts even with massive standing speakers absolutely old. This Kinky transparency and ease, as no eye stays dry. The digitally generated bass kidney and the DSP control aimed at maximum fidelity not less than are a stroke of genius. Why did no one previously?
