iBX Technology

Dynamic Bass Extension

Dynamic Bass Extension

Built into the Kube12b is dynamic bass response iBX technology, an enhanced form of DSP that will analyse your input signal acutely to ensure the subwoofer will play louder whilst remaining dynamic at any listening level.

KEF’s Intelligent Bass Extension algorithm creates extra depth to unlock the full potential of Kube12b’s custom 12” bass driver. Enjoy an immersive music and home theatre sound that will fill your space.

Dynamic Bass Extension

Wide Frequency Range

Loud and Deep

Loud and Deep

As the largest woofer in the KEF Kube range, the 12” bass driver built into the Kube12b is capable of packing a punch with a sizable 114dB maximum output.

It’s also capable of translating a wide frequency response range of 22Hz - 140Hz, meaning you’ll experience a wide breadth of bass tones and deeper frequencies when connecting your speaker system to the KEF Kube12b.

Meet the Kube range

Meet the Kube range

Kef have developed three subwoofers in the Kube range to suit a variety of room sizes: the Kube8b, Kube10b and Kube12b. Each powered by the same 300W RMS Class D amplifier, the driver size in each Kube woofer steps up to 8”, 10” and 12” as you move up the range.

The maximum sound output also reaches greater volumes as you move between Kubes, from 105dB in the case of the Kube8b, to 111dB for the Kube10b and up to a punchier 114dB in the Kube12b. This also equals a greater frequency response as the subwoofers get larger, allowing for greater bass impact.

A flexible range of connection options makes the Kube12b unmatched when it comes to convenient speaker system set ups.

A range of LFE, line and speaker level inputs, phase selection and DSP controlled EQ settings are all accessible on the rear of the unit, making it easy to achieve your desired end result.
