The redesigned Tzero MKIII is powerful, articulate, and delivers surprisingly deep bass, filling smaller spaces with ease. With the MKIII subwoofer, we set out to design and build the best bass engine imaginable for its application.

Punching far above its weight, Tzero MKIII brings a sense of authority and control that feels unexpected from something so compact. Its 100-watt high-current NextGen Class D amplifier delivers bass that’s tight, confident, and effortlessly musical.

Brains & Brawn
