SOUND
Hear new dimensions in sound with Kube subwoofers
The Kube 12b effortlessly unleashes explosive power. iBX technology dynamically extends bass depth and KEF’s unique ability to design, build and integrate the driver in-house takes optimisation to a whole new level. Delivering immersive music and home theatre sound that takes you to the heart of the performance.

Great size and enough deep punchGreat deep sound with enough punch to get perfectly along with the LS50 system. Size is ideal to find a place. I definitely can recommend the Kube 8b

Great match for LS50The smaller 8” driver in the KUBE8b makes it an excellent companion to the KEF LS50. I use it in my home office as a 2.1 system.
