KEF Kube12b
KEF Kube12b | Experience new dimensions in sound with Kube subwoofers
The Kube 12b effortlessly unleashes explosive power. The iBX technology dynamically extends the bass depth and KEF’s unique ability to design, build and integrate the driver itself takes optimization to a whole new level. With immersive music and home cinema that takes you to the heart of the performance.
Integration
KEF may be the only high-end manufacturer that designs, engineers and assembles drivers, cabinets and circuitry in-house. This level of integration means that we are committed to pure sound and the Kube remains true to this ideal. The result is a driver and amplifier that are perfectly matched.
KEF Kube12b – Urgency
Deep, deeper at its deepest. KEF’s design and engineering team worked at a chord to develop iBX. This intelligent bass extension algorithm creates extended depth that exploits the full potential of the individual driver.
The result is unparalleled precision in the KEF Kube12b. And the highest synchrony between amplifier, driver and closed cabinet.
Simple configuration of the Kube12b
Kube subwoofers offer unmatched placement flexibility. A range of LFE, line and speaker level inputs, phase selection and DSP-controlled EQ settings help you get the most out of a Kube.
Place it in a convenient location, match it to any main speaker or type of music system, and start discovering new depths in sound.
