Product Features
| 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. |
| 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. |
| 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. |

| KUBE12b Review & 5-Star Bass: Best Subwoofers of 2017/2018 Award |
| "Reviewed as part of KEF’s 5.1.4 Dolby Atmos-enabled Q Series system, the Kube12b received high praise from veteran reviewer Mark Fleischmann, who gave the 12-inch/300-watt subwoofer 5 stars for Performance and Value. He was particularly enamored with how the sub handled the “thunderous” pipe-organ blast on Vaughan Williams’ Job/Symphony No. 9 (Chandos SACD). “I’m impressed by how much performance KEF got out of the $700 price of the Kube12b sub,” Fleischmann wrote. “A legend has to be earned. KEF continues to earn it.” |

| KUBE12b Review & 2018 Top Choice Award |
| “In the past, KEF may not have been on your radar when it comes to affordable high-performance subs. But competition among subwoofer makers is fierce and now things are different. For delivering something close to the ideal “living room sub” at its size and price point, I’m giving the KEF Kube 12b a well-deserved AVS Forum “Top Choice 2018” award." |

| KUBE12b Review |
| “Outside of the budget-busting (for me, at least) $1700 R400b, I've never been a huge fan of KEF's more affordable subwoofers, but that all changes with the KUBE 12b. Powered by a 300w Class D amp and custom circuitry, the 12b punches above its class and capabilities, producing deep, buttery bass perfect for those who love to FEEL music and movies." |
