Advanced Music System

That performance comes from extra dedicated drivers and amplifiers built into each BXT, handling the lowest frequencies and reaching down to bass you feel in your chest as much as your ears. The result is a wide, layered soundstage of real depth and effortless dynamics – music you don’t just listen to, but step inside.

Already own a pair of Kii THREEs? Adding BXT modules is one of the smartest upgrades you can make. You keep the speakers you already love and transform them into a full-range floorstanding system, gaining real bass extension and scale without starting over. That’s the beauty of Kii’s modular thinking: more performance, the same elegant footprint, and an investment that builds on what you’ve already got.
