KEF Kube 12 MIE Powered Subwoofer 12"

Deep, clean bass for all your entertainment

The Kube 12 MIE brings together KEF's careful speaker design and high-tech digital signal processing for bass that's clean, deep, and satisfying. This hefty 41-pounder uses a custom 12" woofer in a sealed cabinet, driven by a built-in 300-watt Class D amp.

Your viewing, listening, and gaming experience will be enriched by the substantial bass. Yes, the midrange and high frequencies are responsible for conveying detail and definition, but the bass is where the emotion lives. KEF's Music Integrity Engine® digital signal processing algorithms add depth, output, and dynamic range to the sub's presentation. And IBX Intelligent Bass Extension makes thousands of adjustments per second, to lower distortion and enhance your entertainment with world-class accuracy.
