    Good bass response, seems to enhance the low end especially with music.

    The salesperson ann in-home consult recommended KEF. I also have KEF in-ceiling speakers, which are great. However, the subwoofer seems to be lacking in sound quality. I do not know anything about audio other than that I like good-quality surround sound. So considering my expectation of having a booming subwoofer similar to a rocking car that passes you on the road, I am disappointed, assuming that expectation is correct. If it is not, then I guess it does the trick. At least, I am not rocking the house down.

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

    Not a big sound guy, but I needed a good subwoofer for my family room setup. This thing hits. It’s very easy to fine tune the amount of bass you want and it’s very easy to connect to a receiver. Pretty much, plug and play. One thing though, this cube is big. I didn’t pay attention to the dimensions. Luckily, it was no problem for my current layout.

    Could no hear any difference with this subwoofer connected and its volume maxed out versus my full range floor standers alone, after carefully matching levels and playing stereo music. Overall it feels under-powered, I would take 300W spec with a grain of salt.

    Awesome medium sized sub

    Posted .

    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!

    The spoed of this sub is incredible, especially for a non ported sub. It has the ability to recover to send out the next song note, kick drum, or movie explosion. Closest thing you can get to REL for half the cost.
