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.

Nice, sturdy kit...would buy again!
Size: 4-tier, Style: wall mount&floor mount, Size: 4-tier, Style: wall mount&floor mount
Purchasing this kit instead of each piece of pipe and fittings required was a no-brainer. It was especially easy because all pieces are prepainted. It went together with ease. Mounting was simple with planning, measurements, and a level. *Note* I purchase the pine stair treads from Home Depot that are 1" thick and then chemically aged them before adding polycrylic. It is cheaper than plywood and shelving boards, and a full 1" thick rather than 1x12 shelving.

Looks amazing!
Size: 4-tier, Style: wall mount&floor mount, Size: 4-tier, Style: wall mount&floor mount
Very straight forward to build. Mine was not hard but to a bit more effort because my ceiling is at an angle so I had to get a little creative. I cut a piece of wood and placed it between the ceiling and one of the arms for it to be even. It’s also not completely even cause I didn’t have a long level but still looks amazing.

Very easy to put up and assemble!
Size: 48 inch 3 Tier, Size: 48 inch 3 Tier
We were looking for a nice shelf over our coffee bar, and this industrial pipe shelf was perfect! This was very easy to assemble! Simply put in your anchors and screw in the bases! We ordered the three tier shelf but only needed two, and it was very easy to make that adjustment! I loved that this was solid wood shelving rather than particle board.

beautiful and sturdy
Size: 48 inch 2 Tier
The shelf is beautiful and sturdy. The only small complaint are the instructions to put it together are deceiving because pieces were put together for shipping purposes (we assume) but didn't actually go together which took us a few times to figure out. I recommend putting it together off the wall before trying it on the wall so you know what pieces go where.
