Customer Ratings & Reviews

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.

I like the size. It's a little larger than a one foot cube but produces a tremendous low frequency sound that is not boomie and is capable of filling a 14x22 foot room. I don't like the fact that it does not have auto on/off capability. Other than that it is great.

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.

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.

perfect size and power. I will be getting a second one to complete a 7.2 set up later this year

It’s big, and it sounds great. Brings out the best of my Kef R5s.

This is the perfect size woofer for a medium size room excellent quality great sound

Just what I needed to add to my bookshelf speakers. Nice and unobtrusive.

This thing is really big . i have this behind me & you feel like you are in the movie.

You get a big sound from this little subwoofer. It is the perfect size if you have a small room.

Hands down the best relatively compact sub! I was looking for a relatively small sub for my medium sized basement home theater. I needed some extra low end reach for my Goldenear Triton Three speakers and surrounds. The Kube12b fits the bill perfectly, even the matches the look with the gloss top and fabric sides. The KEF is an understated sub that does not draw much attention, which is good for the decor and spouse approval. As for performance, it is unbelievable! Now movies and music have some extra depth (but not bloat) from the Kube 12b. The real world measurements are impressive. In my room, I can get a FLAT corrected EQ curve to 15Hz at about 75db from Anthem Room Correction, WOW! I did a head to head with an SVS SB 2000 and the Kube12b produced 7-8db louder response from 15-25 Hz which is exactly where I want more output. The corrected sub EQ curve for the SVS tailed off at about 18 Hz. Needless to say I kept the KEF. This is the best relatively compact sub hands down that won't overwhelm a room with its size!
