The KEF Kube 15 MIE active subwoofer is the undisputed king and largest model in the revamped Kube range. Engineered to deliver the deepest possible bass for music and movies, it draws you right into the heart of the action with physically tangible, earth-shattering bass. The combination of a massive 380mm (15") long-excursion forward-firing driver and an efficient 300W Class D RMS amplifier creates the most powerful and visceral bass performance, easily filling even the largest venues and dedicated home cinemas.

 The full control of such a large diaphragm is provided by KEF’s exclusive Music Integrity Engine® (MIE) algorithms. This advanced DSP (digital signal processing) system ensures that all the components of the subwoofer work in perfect synergy. Part of this technology is the iBX Intelligent Bass Extension algorithm, which analyses the audio signal on the fly and dynamically extends the depth of the bass at any listening volume. This means that the bass remains incredibly precise, fast and clear, whether you’re quietly enjoying an evening of audiophile recordings or demanding the full power of the most demanding Hollywood action spectacles.

 Despite its brutal power, the Kube 15 MIE maintains exceptional sonic refinement thanks to its fully sealed enclosure. The sealed construction eliminates any airborne noise and delivers exceptionally articulate and solid bass, while making it much easier to find the ideal position in the room. To ensure perfect fit and perfect adaptation to the acoustics of the room, 3 preset EQ position options are provided, optimizing the sound depending on whether the subwoofer is freestanding in the room, against a wall or pushed into the corner of the room.

 Connecting to any system is made easy with KEF SmartConnect technology, which automatically detects the type of input signal, and in addition to the classic RCA inputs, there are also speaker level inputs (speaker level inputs via Euroblock). For spaces where running long and thick cables is not an option, the Kube 15 MIE includes a dedicated expansion slot for the KEF KW1 wireless kit, which allows wireless transmission of low frequencies in full Hi-Fi resolution. With a modern and refined design, this powerful subwoofer will fit reliably and elegantly into your living space.
