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

Your room, your rules. Kube subwoofers offer unmatched flexibility in configuration. With a range of LFE, line & speaker-level inputs, Phase selection and 3 DSP controlled EQ settings to help match your sub to any room placement, you’re in control right out of the box. Set up the Kube where it’s most convenient to you, match it to any main speaker or with any type of music system and start exploring new depths in your sound.

KEF Kube Subwoofer Integration

Integration
We’re on the same page. KEF is quite possibly the only high-end manufacturer who designs, engineers and assembles the driver, cabinet and circuitry in-house. This level of integration is the hallmark of our commitment to pure sound and the Kube stays true to that ideal. What you get is a driver and amplifier so perfectly attuned they sing in absolute harmony.

Explore new dimensions in sound with Kube, KEF’s powerful range of subwoofers that open up sound’s hidden depths.
Each elegantly designed, fully sealed unit unleashes explosive power effortlessly, intuitively, intelligently. iBX technology extends the bass depth dynamically, unlocking the full potential of the driver’s power at normal listening levels or even the most extreme. And with KEF’s unique capability to design, build and integrate the driver in-house, we take optimisation to a whole new level. Delivering immersive music and home theatre sounds that drive you deeper into the heart of the performance.

KEF Recertified Product

Buying a KEF open box product is a great way to get "like-new" products at a considerable savings. Every product has been thoroughly tested, cleaned and otherwise renewed to original condition. Next it’s repackaged in a new box with all original accessories included. And for your piece of mind and protection, your purchase is covered by a full 5 year parts and labor warranty (1 year on electronics) valid at any authorized KEF repair center (you can look-up locations online here or call 732-683-2356)

Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked cabinets, broken grilles, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
