12-inch bass driver active subwoofer

The Kube12b is engineered to deliver the deepest bass for music and movies, if you want to feel the earth move look no further.

Perfect for creating a deep and clean rumble in large rooms. The Kube 12b has a 300 Watts Class D amplifier and a large 12-inch driver as well as iBX technology to dynamically extend bass depth.

The Kube 12b effortlessly unleashes explosive power. iBX technology dynamically extends bass depth and KEF’s unique ability to design, build and integrate the driver in-house takes optimisation to a whole new level. Delivering immersive music and home theatre sound that takes you to the heart of the performance.

KEF is quite possibly the only high-end manufacturer that designs, engineers and assembles the driver, cabinet and circuitry in-house. This level of integration means we are commited to pure sound and the Kube stays true to that ideal. The result is a driver and amplifier that are perfectly in tune.
