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.

Great looking shoe!
Size: 11 Little Kid, Color: Tan, Size: 11 Little Kid, Color: Tan
We got these sandals specifically for our Caribbean vacation over thanksgiving break. They run true to size but I did get them one size bigger to hopefully last for next summer as well. They look great on and go with everything! My son said they feel very comfortable on his feet and he likes easy on/off due to Velcro closure.

The Perfect Sandal for Active Kids!
Size: 8 Toddler, Color: Navy
I recently purchased the Stride Rite 360 Boy's Paddy Sandal for my son, and I couldn't be happier with my decision! From the moment he slipped his feet into these sandals, I could tell we were both going to be very pleased. Comfort & Fit: 5/5 - The Paddy Sandal has surpassed all expectations in terms of comfort and fit. The adjustable straps make it incredibly easy to get a snug, perfect fit for my son's feet, ensuring the sandals stay securely on, no matter how much running and jumping he does. The soles are cushioned just right, offering support without sacrificing flexibility, which is essential for a growing child. Durability: 5/5 - Stride Rite has always been synonymous with quality, and these sandals are no exception. They've endured days at the park, sandy beaches, and endless pavement adventures, yet they show minimal wear and tear. The materials are top-notch, promising many more months of active use. Ease of Use: 5/5 - For busy parents, the ease with which these sandals can be put on and taken off is a huge relief. The hook and loop closure is strong and stays in place, but it's simple enough for my son to handle on his own, fostering his independence. Overall Experience: 5/5 - It's rare to find a shoe that ticks all the boxes for both parent and child, but the Stride Rite 360 Boy's Paddy Sandal does just that. They've been a fantastic investment in my son's summer wardrobe and overall comfort during his daily activities. I would highly recommend these sandals to any parent looking for a reliable, comfortable, and stylish option for their child. Stride Rite has outdone themselves once again!
