Description

The deep rumble in your big living room. With a large 12-inch driver, the Kube12b is the largest of the family. Delivering a deeper bass for large rooms.

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.

Immersiveness

iBX, developed by KEF’s design and engineering team, is an Intelligent Bass Extension algorithm which creates an extended depth that unlocks the full potential of the custom driver to give you unparalleled precision and ultimate synchronicity between amplifier, driver and sealed cabinet. 

After analysing the input signal, the DSP employs KEF's iBX algorithm which enables the subwoofer to reproduce audio at louder listening levels while maintaining its dynamic quality.

Easy configuration

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. The Kube can be matched to any core speaker, set up to your convenience, or with any music system so you can discover new levels in your sound.

Integration

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 their 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.

Installation

After identifying whether inputs are mono or stereo, KEF's SmartConnect technology smartly tweaks the volume of the subwoofer for optimal performance. Included are placement tuning presets for Freestanding, Wall/in-cabinet and Corner meaning the Kube sounds perfect wherever it’s installed.
