Work with Kii

Today’s studio business is constantly evolving. Audio software has enabled a democratization of music production, along with some great possibilities and also a lot of challenging changes to overcome for professional engineers. Yet for recording, producing, mixing and mastering a single piece of gear still is as important as it has ever been: the monitoring system! Having a transparent and revealing monitor system that translates your work perfectly to the outside world has become more important than ever. It is the centerpiece of the modern studio. As an audio professional you’re always looking for ways to raise the bar of sonic performance. You want a clear, reliable and consistent advantage over your competition. The Kii THREE system is that advantage.


Whether you work in a major facility, independent recording studio, or from your home studio, a good monitoring situation enables you to work faster, easier and achieve better results everyday. It takes the guesswork out of any decision during a production, so you can be safe and bold with your decisions and move through a project quickly, focusing on what´s really important in the studio: the musical ideas, the artistic expression and the interaction with your clients!

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.


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 midrange driver.

With classical crossover filters, loudspeakers can only have a time aligned impulse response on the main axis. The animations on the right 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 equalised. 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.
