Our take on the KEF Kube 12 MIE 12" Subwoofer (Gloss Black)

The Kube 12 MIE is the largest subwoofer in KEF's Kube line: a front-firing 12-inch long-throw driver driven by a 300W Class D amplifier. KEF's Music Integrity Engine DSP, including iBX Intelligent Bass Extension, keeps bass deep and controlled at any volume. It suits larger rooms and home theaters where output and low-end depth matter more than a compact footprint. Against smaller sealed subs it trades size for output and extension; against pricier KEF models it gives up some refinement and app control.

What reviewers say

Owners of the Kube range describe strong, deep bass for movies and music and easy setup with common receivers. Some note the larger cabinet and that fine tuning is basic compared with subs that offer app EQ.

About the KEF Kube 12 MIE 12" Subwoofer (Gloss Black)

The KEF Kube 12 MIE is a 12-inch subwoofer in a gloss black finish. It uses a front-firing long-throw driver with a large cone area and high excursion, driven by a 300-watt Class D RMS amplifier. It is the largest model in the Kube range and has the highest output, for movies, music, TV and gaming in larger rooms and dedicated home theaters.

KEF's Music Integrity Engine (MIE) uses digital signal processing algorithms to tune how the subwoofer's components work together. iBX Intelligent Bass Extension provides deeper, more precise bass at any listening level. The cabinet is sealed.

It connects through KEF SmartConnect and speaker-level inputs. The optional KW1 wireless adapter (sold separately) lets you place the subwoofer without running cables. Three room position EQ presets adjust its sound to where it sits in the room. Power modes include Auto wake up, Always on and 12V trigger.

Questions and answers

Is the Kube 12 MIE good for movies or music?
Both. The 12-inch driver and 300W amp give the output and depth movies need, and the DSP keeps music bass controlled at lower volumes.
How does it compare with the smaller Kube models?
It is the largest and highest-output Kube, with a bigger driver and more low-end than the 8- and 10-inch versions. Smaller models suit compact rooms better.
Do I need the KW1 wireless kit?
No. It connects by cable out of the box. The KW1 is optional and lets you place the sub away from the receiver without a cable run.
What connections does it have?
It offers KEF SmartConnect and speaker-level inputs, so it works with most AV receivers and stereo amplifiers.
Will it work in a small room?
It can, but its output is tuned for larger spaces. In a small room you may need to keep the gain low to avoid boom.
What is in the box?
The subwoofer itself; the KW1 wireless kit is sold separately. Check the listing for included cables.
Where is the KEF Kube 12 MIE 12" Subwoofer (Gloss Black) cheapest?
At World Wide Stereo, for $949.99, as of our latest check.
