Effortlessly unleashing explosive power on demand, the unique iBX technology in Kube 12b dynamically extends bass depth, delivering immersive music and home theatre sound taking you to the heart of the performance. Go deep, or go home!
KEF’s design and engineering team worked in chorus to develop iBX, an Intelligent Bass Extension algorithm which creates extended depth to unlock the full potential of the custom driver. Unparalleled precision and ultimate synchronicity between amplifier, driver and sealed cabinet.
KEF Kube subwoofers offer unmatched set up flexibility: A range of LFE, line and speaker-level inputs, phase selection and DSP controlled EQ settings help you get the best from your Kube. Put it in a convenient position, match it to any main speaker or type of music system, and start exploring new depths in the sound.
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 they remain committed to pure sound, resulting in a driver and amplifier that are perfectly in tune.
