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.

Not for super chewers
Color: Blue
This ball seems to be of good quality; has held a charge well and is easy to use. Sadly, the cover lasted less than 15 minutes with our dog.... not for aggressive chewers for sure. Pretty funny to watch the hound dog jowls shake though.

Great fun for dogs!
Color: Orange
Two of our dogs really love this! It caused a lot of barking and chasing and running around trying to grab it. It's really funny to use the remote to control it (and especially make it stop when things get a little too chaotic!) It feels durable even when pawed and bumped into and stepped on. The battery life seems good. I plugged it in overnight to charge so not sure how long it took to charge, but it has lasted quite a while with the dogs playing with it and still doesn't need a charge. It's easy to screw off one side of the ball to plug it in to charge. The size is a little bigger than a tennis ball I would say and has a soft texture.

It doesn't work.
Color: Blue
The two halves of the ball shell come apart again and again when the dog plays with them. When it is time to recharge the core, it will not take a charge. The dog loves it, but it's unsafe to play with.

My dogs fight over it
Color: Orange, Color: Orange
Easy to use, durable, and has a great battery love. At first my dogs were curious and unsure about it, now its become one of their favorite toys. They'll stare at it while its being charged and impatiently wait for it so they can have fun again. Perfect size for most breeds.
