Kube8b Subwoofer

Quick Specs

  • Type: Speakers
 
8 inch active subwoofer

Don't let its compact size fool you, the Kube 8b may not take up much space but the bass it delivers is anything but small.

With an 8 inch driver the Kube8b is perfect for smaller living rooms. It shares the 300 Watts Class D amp as the larger Kubes, as well as iBX technology to extend the bass depth dynamically.



Hear new dimensions in sound with Kube subwoofers
The Kube 8b 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 commited to pure sound and the Kube stays true to that ideal. The result is a driver and amplifier that are perfectly in tune.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
