Unbelievable speaker. Goes down to 20 hz AND sounds good in your room.

DSP controlled speaker w/analog and AES3 format inputs, heavy duty, dark gray spatter paint finish

a linear frequency response, a perfect impulse response and phase coherence,  also  1500 watts per speaker divided across six drivers into a compact and lightweight enclosure. The Kii THREE is able to move some serious air, but doesn't stop there. Instead Bruno Putzeys invented the Active Wave Focusing technology, that controls the sound dispersion and directs the sound pressure, where we need it to be: Into the sweetspot! Intelligent DSP processing provides the kii three with a cardioid sound dispersion pattern down to the low-mid and bass frequencies, which otherwise can only be achived by very wide baffles, big cabinets or soffit mounting speakers (infinite baffle design). The controlled sound dispersion is the only reason, why a big main monitor system in a good room offers the special feel and impact it does. Even though acousticians and speaker designers know about this task, no other speaker manufacturer has approached a solution to this common problem. We designed the Kii THREE with the acoustical challenges of todays studio setups in mind. It fits everywhere and can be the one and only monitor solution you need for every task. It really is the first „Mini Main monitor system“ available. We also think it looks rather beautiful.

Price is $5747.50 for each speaker. $11495- for the pair

The Kii control is sold separately.

Founded in 2015 and led by CEO Chris Reichardt and CTO Bruno Putzeys, Kii Audio has, in a very short period, established itself as a leading manufacturer of high performance monitors. The first product from the company is the Kii THREE digital speaker system. 

Having worked with both Reichardt and Putzeys in previous collaborations, we knew that their new foray into the loudspeaker world would be good. What we didn't know is that it would be this good

Evaluations of the Kii THREEs  left us picking our jaws up off the floor. Subsequent evaluations at some of the bigger commercial studios around the region have reinforced these impressions. These speakers are unlike anything else available, especially with their cunningly compact size and stunningly enormous sound. They have gone up against speaker systems costing twice as much and have come out the favorite. So when the opportunity arose to help represent these great people and their superlative products, we were all in.

Big Little Speakers - Kii THREE

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.

The Kii THREE delivers true "big speaker performance“ from a decidedly small box. To achieve this, Kii invented Active Wave Focusing, which is a combination of a special 4-way DSP crossover filter with drive units mounted front, side and back that "throws" the sound towards the listener instead of bathing the room in it. While cardioid beam forming as a technique of dispersion has been previously achieved, the Kii THREE radically improves on it by maintaining a cardioid response over the full audio band. The wave front appears as if radiated from a single point just in front of the speaker, meaning that the time coherence of the wave front is fully maintained on and off axis. This translates to an impressively wide sweet spot and spacious stereo field with pinpoint accurate imaging.

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 monitoring product. 

Better Mixes, Faster

The Kii THREE is extremely revealing of EQ, compression and effects, saving you from nasty surprises when you check your mix on another system. Effortless presentation allows for longer, more productive mixing sessions without ear fatigue. In the end you will work faster with better results and be more confident that your mixes will translate. 


The ultra compact controller/preamp/USB Interface for Kii THREE Loudspeaker.

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.

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). 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 to the Kii THREE speakers 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 Kii THREE Boundary and Contour settings, while also providing access to more advanced system settings, including amongst others: manual power on/standby, LED brightness, DIM function and limiter indication. The main functions like volume, source and mute can also be remote controlled via your IR Remote (RC5 type or Apple Remote).
