KEF Kube 8 MIE Subwoofer, Black Overview

KEF

View this description in German

The KEF Kube 8 MIE Subwoofer is a compact eight-inch active sub and the smallest of KEF's Kube MIE range. It's designed for smaller spaces like gaming rooms, offices, or small lounge areas and easily fits around desks and other furniture. Kube 8 is enhanced by KEF's new proprietary Music Integrity Engine (MIE); a set of DSP algorithms which optimise performance for increased depth and dynamics. With MIE and a 300-watt Class D amplifier, you can expect heightened accuracy and full-bodied sound even at high volumes. Refine your hi-fi, home cinema or gaming system's bass performance with intuitive room position EQ settings, SmartConnect (to detect mono and stereo signals automatically), and various auto-power modes.
