Key Features
The KEF Kube 10 MIE Subwoofer is a ten-inch active sub ideal for standard/medium-sized rooms. It's well suited to hi-fi, home cinema and gaming applications where accuracy is the primary sonic objective. This is partly thanks to 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. Being a sealed cabinet with a front-firing driver, the Kube 10 can be placed closer to walls and cabinets without fear of distortion. As well as more flexible placement, you can further refine your bass performance with intuitive room position EQ settings, SmartConnect (to detect mono and stereo signals automatically), and various auto-power modes.
