    Great choice for small or medium listening rooms

    I purchased the KEF Kube 10b to complement a pair of LS50 Metas in my 2-channel setup. I'm very pleased with the performance as well as build quality and can highly recommend the Kube 10b in small to medium rooms especially for music. It wasn't difficult to find the right location in the room as well as "dialing in" the settings regarding low pass and type of EQ (three choices including on wall, in room, etc) to achieve the best blending with the LS50s (may incorporate a MiniDSP later to fine tune). My guess is that it would be a good choice for HT as well but you might need two to get the best result in larger rooms. For "bass heads" or high volume HT applications it might make more sense to purchase a ported subwoofer or two or plan on two of these or the 12b models.

    Tight and musical

    I have a set of Definitive Technology Mythos that I purchased in 2004. I set them up in my home gym, but needed an appropriate subwoofer to compliment them. The KEF Kube8b was a wonderful choice. The room is the size of a large bedroom. The Kube8b has plenty of punch, while blending beautifully with the DefTecs.

    Team KEF!

    The KEF R-Series packages are worth every penny. The quality for music lovers exceeds expectations. I have also added the Center and towers to the set. Comes in many colors - easy to install. Top notch! Highly recommend!
