    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.

    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!

    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.

    Thundering Ice Kube

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This 12" driven enclosed glossy/ ice cube shaped subwoofer is not only a beauty to behold but very well capable of shifting enough air to cover a large listening space. It has fast responsive bass that is tight but also more than able to provide the earth shaking sonics needed during movie watching. This unit comes alive in the 30Hz range, handing out well rounded bass with great depth and with pace. It can deliver down past the 20Hz with lower frequencies tapering off and never dropping suddenly. The built in KEF DSP allows set up to be easy, configure in-cabinet, corner or in-room, then either let your AVR handle the rest or adjust the volume and crossover to your liking.

    Balanced and even, but booms when you need it. My music is even high/mid/low. The KEF Kube 12" is subtle, yet noticeable. For movies, the subwoofer can rattle things and I had to turn it down a little.

    Amazing bass sound from this little unit. it's a part of our theatre room set up and the sound fills the room and rounds out the rest of our KEF system so nicely.

    Compared to other less expensive, similarly sized sub-woofers I have owned, this is by far the best bass sounds I have experienced. Thanks to Jon Hatcher for his recommendation.

    Excellent for any system that needs to extend the lower audio frequency response range , very dynamic and the excellent damping factor from the class d amplification provides no obvious ringing resonance's that make you think more is there ,this is very accurate for the price range,, the SPL claim is accurate to 400-600 sq ft room ,," 2E tech "

    Very nice add to home theater since old sub was broken. Listening to the KEF knew it was excellent albeit expensive. Encourage all to go in to store and sample.

    Te KEF Kube 10 offers amazing bass. The 10 inch subwoofer performs like a 12 inch subwoofer. It looks amazing with its glossy top. It is well worth the money.

    Kef 10"sub hits pretty hard and fills my 22'×24' den with plenty of bass to compliment my LS 50s. Not quite rap level bass but definitely Acdc rock/roll
