|Explore new dimensions in sound with Kube, KEF’s powerful range of subwoofers that open up sound’s hidden depths.
Each elegantly designed, fully sealed unit unleashes explosive power effortlessly, intuitively, intelligently. iBX technology extends the bass depth dynamically, unlocking the full potential of the driver’s power at normal listening levels or even the most extreme. And with KEF’s unique capability to design, build and integrate the driver in-house, we take optimisation to a whole new level. Delivering immersive music and home theatre sounds that drive you deeper into the heart of the performance.
Go deep or go home. KEF’s design and engineering team worked in chorus to develop iBX. This Intelligent Bass Extension algorithm creates an extended depth that unlocks the full potential of the custom driver. Giving you unparalleled precision and ultimate synchronicity between amplifier, driver and sealed cabinet.
Your room, your rules. Kube subwoofers offer unmatched flexibility in configuration. With a range of LFE, line & speaker-level inputs, Phase selection and 3 DSP controlled EQ settings to help match your sub to any room placement, you’re in control right out of the box. Set up the Kube where it’s most convenient to you, match it to any main speaker or with any type of music system and start exploring new depths in your sound.
We’re on the same page. KEF is quite possibly the only high-end manufacturer who designs, engineers and assembles the driver, cabinet and circuitry in-house. This level of integration is the hallmark of our commitment to pure sound and the Kube stays true to that ideal. What you get is a driver and amplifier so perfectly attuned they sing in absolute harmony.

Great size and enough deep punchGreat deep sound with enough punch to get perfectly along with the LS50 system. Size is ideal to find a place. I definitely can recommend the Kube 8b
Great match for LS50The smaller 8” driver in the KUBE8b makes it an excellent companion to the KEF LS50. I use it in my home office as a 2.1 system.
