    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!

    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.

    Thundering Ice Kube

    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.

    Nice Power in a Small Package

    Having a smaller, open family room space I didn’t want, or need, a 10 or 12 inch sub-woofer. Keeping the nails in the walls, and pictures hanging seemed to be a good thing. I spent some time with the BB salesperson and once he understood where I was at, he went right to the KEF 8” unit. This thing has more than enough juice to make sure you experience Maverick at his best or Smaug in all his glory without making the windows wish they were better quality. Smaller unit can be tucked away and it’s beautiful black finish makes it easy on the eyes if you do see it. Brits did a nice job with this product. Just follow the instruction suggestions to get great bass and low end response.

    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.

    Cleaner sound than more expensive subwoofers. No distortion perceived even at high volume. I would recommend this subwoofer to anyone.

    Adds lots of bass. Had to purchase separately a subwoofer decoupling kit for the feet due to being installed on hard tile. The included rubber feet that are installed from KEF cant hold back the sheer power of this subwoofer. If you're planning to install it on a solid cement floor and are okay with rattling the walls you might not not need a decoupling kit.

    I added this to go with the KEF floorstanding and center channel speakers I purchased. Was initially concerned that the KUBE8 wouldn't be strong enough to fill my 24 x 17 open living room, but I was pleasantly surprised with this subwoofer. I had listened to SVS and a few others in the magnolia room and was leaning towards one of the other brands. Once I got this into my room, it filled the room with more bass than I was expecting from this little sub. The little KEF KUBE8 did a great job for me and I'll be keeping it!

    I use this KEF subwoofer in a big room and it is way more than enough. I highly recommend because of its compact size and quality. This is a very high end sounding piece of equipment. I also have a KEF subwoofer in our bedroom set up and it works great there as well.

    Surprising amount of kick for a smaller unit. Considering a second for a 5.2.4 setup, but one just might be enough on its own.

    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 "
