Kii THREE Feature
When the press release named Kii Audio as the sender, my ears pricked up. When their novel Three loudspeaker promised 20Hz – 20kHz bandwidth from a 20x40x40cm box with six drivers; six 250-watt custom nCore amps; full DSP control and controlled dispersion… my ears got hot and bothered. When I learnt that former folks from Grimm Audio were involved including Bruno Putzeys of Hypex, UcD, nCore and Mola-Mola fame, I got my thermometer out just in case. It pegged. Time for another keep-it-honest installment.

As it turned out, my time-delay notion had some truth to it but didn’t really capture the essence of Bruno’s dispersion control. Which isn’t surprising. I’m a techno peasant. Bruno is one of the sharpest pencils in the drawer. Talking to the man after his first demo, he explained how it exploits strategic phase shift which is a form of time delay after all. Rather than a delay line however to hold back the frontal drivers as I envisioned, his purpose is to create a cardioid dispersion pattern. He thus exploits phase cancellation to seriously attenuate rear-firing acoustic energy below 250Hz. What it means is that front-wall reflections in the lower registers are way down in level; and the usual build-up of high-amplitude compression zones in the front corners which trap HF and imbalance sound distribution is eliminated.
