8-inch bass driver active subwoofer
Don't let its compact size fool you, the Kube 8b may not take up much space but the bass it delivers is anything but small.
With an 8-inch driver the Kube8b is perfect for smaller living rooms. It shares the 300 Watts Class D amp from the bigger Kubes and has iBX technology to extend the bass depth dynamically.
