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 "

Much more solid bass than the power rating indicates. I swear this sounds like a 800 watt amp. I love it...and reasonably priced! Traded in another subwoofer for this one and I couldn't be happier with the outcome!

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.

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.

Very impressed with the kef Kube 8b subwoofer. Perfect for a small to midsize room. This sub packs a punch and produces low but tonally controlled bass notes. Sounds great paired with my KEF LS50 wireless setup. Definitely worth it.
