KEF KUBE 12B Active subwoofer 12inch 300W

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.

The SX-120 subwoofer was designed from the ground up by our engineers in London, with a custom-designed 8-inch driver and a powerful 70W RMS amplifier. Components were hand picked by our in-house engineers and then painstakingly voiced to provide premium sound quality
