10 inches bass driver active subwoofer

The mid-sized Kube 10b has a sealed cabinet, 10 inches bass driver and 300 Watts to produce serious extension and control. The latest addition to KEF's powerful range of subwoofers opens up sound’s hidden depths thanks to 300 Watts of Class D power integrated with a 10 inches driver and iBX dynamic bass extension technology.

Hear new dimensions in sound with Kube subwoofers

The Kube 10b effortlessly unleashes explosive power. iBX technology extends the bass depth dynamically and KEF’s unique ability to design, build and integrate the driver in-house takes optimisation to a whole new level. Delivering immersive music and home theatre sound that takes you to the heart of the performance.

Immersiveness

Go deep or go home. KEF’s design and engineering team worked in chorus to develop iBX. This Intelligent Bass Extension algorithm creates an extended depth that unlocks the full potential of the custom driver. Giving you unparalleled precision and ultimate synchronicity between amplifier, driver and sealed cabinet.

Easy configuration

Kube subwoofers offer unmatched set up flexibility. A range of LFE, line and speaker-level inputs, phase selection and DSP controlled EQ settings help you get the best from a Kube. Put it in a convenient place, match it to any main speaker or type of music system and start exploring new depths in the sound.

Integration

KEF is quite possibly the only high-end manufacturer that designs, engineers and assembles the driver, cabinet and circuitry in-house. This level of integration means we are committed to pure sound and the Kube stays true to that ideal. The result is a driver and amplifier that are perfectly in tune.

This item is vibrant in color, but I could tell right away, It wasn’t going to be durable and indestructible like the description said. My dog had it destroyed in less than a minute.

Comes with pump
Color: Colorful, Size: Large
My dogs enjoyed it but it’s not large dog proof. I have a husky and German Shepard…..the ball lasted a day before it was torn up. But this would be perfect for smaller or medium sized dogs.
