d&b audiotechnik Bi12 Installation-specific Small to Medium Format Ground Cardioid Subwoofer

The Bi12 is a compact cardioid ground subwoofer engineered for fixed installations within the CCLi system. Featuring dual long-excursion neodymium drivers, a front-facing 15" bass-reflex unit and rear-facing 10" bandpass driver, it delivers true cardioid dispersion from a single amplifier channel.

This innovative design minimises rear radiation while maximizing low-frequency control and precision. With a frequency response spanning 39 Hz to 150 Hz, the Bi12 provides powerful, articulate bass extension in a remarkably compact footprint, making it ideal for venues requiring controlled directional low-end performance.
