Kef Kube8b Active Subwoofer
With a 8” bass driver, the KEF Kube8b is the perfect choice for a small-sized room and will easily compliment your set up with a range of LFE, line and speaker-level inputs. With iBX dynamic bass extension technology, you’ll benefit from a deep and optimised low end performance.
iBX Technology
Dynamic Bass Extension
Built into the Kube8b 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 Kube8b’s custom 8” bass driver. Enjoy an immersive music and home theatre sound that will fill your space.
Wide Frequency Response
Loud & Deep
As the smallest woofer in the KEF Kube range, the 8” bass driver built into the Kube8b is still capable of packing a punch with a sizable 105dB maximum output.
It’s also capable of translating a wide frequency response range of 34Hz - 140Hz, meaning you’ll experience a wide breadth of bass tones and deeper frequencies when connecting your speaker system to the KEF Kube8b.
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.
Versatile Design
Easy Connections
A flexible range of connection options makes the Kube8b unmatched when it comes to convenient speaker system setups.
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.
The perfect subwoofer option for a smaller room
