Description

Powerful Low-End Extension, Total Synchronicity, and Limitless Flexibility: KEF KUBE 12b Features a Custom-Integrated 12-Inch Driver, 300-Watt Amplifier, and 56-Bit DSP Preamplifier

Intelligent Bass Extension: It's not only an apt description of the KEF KUBE 12b subwoofer's strengths, but the name of the algorithm the in-house engineering team developed to make this elegant box a standout component. The technology effectively creates an extended depth that unleashes the full potential of the custom-integrated 12-inch driver inside KUBE 12b, resulting in remarkable precision and synchronicity between the 300-watt amplifier, driver, and sealed cabinet. Equipped with a 56-bit MIPS DSP preamplifier, KUBE 12b offers an array of LFE, line-level, and speaker-level inputs for set-up flexibility. Phase selection and three DSP-controlled EQ settings allow KUBE 12b to jive with your room's dimensions and existing speakers. Most importantly, KUBE 12b adds dimensions, details, and dynamics to your music you probably never imagined you could hear with the addition of a sub-$1k subwoofer. But when that model at hand is KUBE 12b – a beneficiary of in-house-assembled driver, cabinet, and circuitry – such axioms instantly change. 100% Music Direct Guaranteed.

"Powered by a 300-watt Class D amp and custom circuitry, the 12b punches above its class and capabilities, producing deep, buttery bass perfect for those who love to FEEL music and movies."

Take Total Control
Your room, your rules. With a range of LFE, line- and speaker-level inputs, Phase selection, and three DSP-controlled EQ settings to help match your sub to any room placement, you're in control right out of the box.

No Shortcuts: Designed, Engineered, and Assembled In-House
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 KEF's commitment to pure sound. What you get is a driver and amplifier so attuned they sing in absolute harmony.
