KEF Kube 12b Subwoofer

KEF Kube 12b Subwoofer

The Kube 12b is engineered to deliver the deepest bass for music and movies, if you want to feel the earth move look no further. Perfect for creating a deep and clean rumble in large rooms, the Kube 12b has a 300 Watts Class D amplifier and a large 12 inch (305 mm) driver as well as iBX technology to dynamically extend bass depth.

This 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, they 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: 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.

Easy Configuration: 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.

Integration: 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 is the hallmark of KEF's 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.
