KEF Kube 12 MIE 12-inch Front-Firing Active Subwoofer

The Kube 12 MIE is engineered to deliver deep, powerful bass and is perfect for creating a heart-pounding rumble for your favourite films, box sets and music. The Kube 12 MIE features a 300 Watt Class D amplifier and a large 12” driver as well as iBX technology to dynamically extend bass depth.

Hear new dimensions in sound with Kube subwoofers

The Kube 12 MIE 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

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.

12" Long Throw Driver

The Kube 12 MIE features a front-firing long throw driver with a large cone area and high excursion, delivering higher output at lower frequencies. Its efficient and cool-running 300W Class D RMS amplifier further enhances performance.

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.

Optional wireless connectivity

The optional KW1 wireless kit enables optimal placement of the Kube 12 MIE without being limited by cables. High-quality wireless transmission ensures the delivery of every nuance and impact from your favourite movies and music.

Multiple control modes

'Auto wake up' detects audio signals for instant readiness, 'Always on' mode keeps it ready to play instantly, and '12V trigger' provides automatic wake-up when connected to compatible devices.

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 they 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.

Runs way too small
Color: Black, Size: Medium
If you live in the U.S. and wear medium, a large will fill you perfectly. I wear large and the “large” is objectively a medium in the chest arms and neck. Fix your sizes.
