KEF Kube 10 MIE 10" Powered Subwoofer 300W BLACK

The KEF Kube 10 MIE is a powerful, versatile powered subwoofer designed to deliver deep, accurate and impactful bass for music, movies and gaming. Featuring a custom-engineered 10-inch front-firing long-throw driver, a 300-watt RMS Class D amplifier and KEF's proprietary Music Integrity Engine (MIE) digital signal processing, the Kube 10 MIE combines impressive low-frequency performance with intelligent bass management in a compact sealed enclosure.

Positioned between the Kube 8 MIE and Kube 12 MIE, the Kube 10 MIE provides an excellent balance of bass extension, output capability and installation flexibility. Its larger 10-inch driver delivers greater low-frequency authority than the smaller Kube 8 MIE, making it well suited to medium-sized listening rooms and home theatre systems requiring substantial bass performance without an oversized cabinet.

KEF SmartConnect technology simplifies integration with stereo and home theatre equipment, while three room placement EQ settings help optimize performance for different installation environments. Compatibility with the optional KEF KW1 wireless subwoofer adapter provides additional freedom when positioning the subwoofer.

Music Integrity Engine Digital Signal Processing

The Kube 10 MIE incorporates KEF's proprietary Music Integrity Engine, a sophisticated collection of digital signal processing algorithms designed to optimize the interaction between the driver, amplifier and enclosure.

Developed using KEF's extensive acoustic engineering expertise, Music Integrity Engine continuously manages bass performance to maintain accurate tonal balance, dynamic impact and controlled low-frequency reproduction.

By optimizing the entire subwoofer system rather than individual components in isolation, MIE helps the Kube 10 MIE deliver consistent performance across a wide range of listening levels.

iBX Intelligent Bass Extension

KEF's iBX Intelligent Bass Extension technology works within Music Integrity Engine to maximize low-frequency extension and dynamic output.

The intelligent processing continuously analyzes the incoming audio signal and adjusts bass performance in real time, helping the 10-inch driver deliver deeper, more powerful low frequencies while maintaining control and minimizing distortion.

This allows the Kube 10 MIE to reproduce demanding movie effects, deep musical bass lines and dynamic gaming soundtracks with precision and authority.

10-Inch Front-Firing Long-Throw Driver

The Kube 10 MIE features a custom-engineered 10-inch (250mm) front-firing long-throw woofer designed to move substantial amounts of air while maintaining precise cone control.

The larger driver provides strong low-frequency output and improved room-filling capability, allowing the subwoofer to reproduce deep bass effects with clarity and impact.

Its front-firing configuration and sealed enclosure contribute to consistent bass performance while allowing flexible positioning within the listening environment.

300-Watt RMS Class D Amplification

A built-in 300-watt RMS Class D amplifier provides the power required to drive the Kube 10 MIE's long-throw woofer with precision and control.

The amplifier is specifically optimized for the driver and cabinet, helping maintain accurate low-frequency reproduction while providing the dynamic headroom required for demanding music and home theatre content.

Its efficient Class D architecture delivers substantial output from a compact amplifier design.

KEF SmartConnect Intelligent Inputs

KEF SmartConnect technology automatically detects whether a mono or stereo RCA connection is being used and adjusts input gain accordingly.

This simplifies integration with AV receivers, stereo amplifiers and other compatible audio components, helping maintain consistent subwoofer output without complicated manual input configuration.

Flexible Line-Level and Speaker-Level Connectivity

The Kube 10 MIE supports both RCA line-level and speaker-level audio connections, allowing integration with a wide range of stereo and home theatre equipment.

RCA connections provide compatibility with AV receivers, preamplifiers and other components featuring dedicated subwoofer or line-level outputs. Speaker-level inputs allow connection to compatible amplifiers without a dedicated subwoofer output.

This flexibility makes the Kube 10 MIE suitable for both modern home theatre systems and traditional two-channel audio installations.

Optional KEF KW1 Wireless Connectivity

The Kube 10 MIE is compatible with the optional KEF KW1 wireless subwoofer adapter system, allowing wireless transmission of the audio signal from compatible source equipment.

Wireless connectivity can simplify placement by eliminating the need for a long signal cable between the audio system and subwoofer. The KEF KW1 adapter is sold separately.

Three Room Placement EQ Settings

Three selectable room placement EQ settings allow the Kube 10 MIE to adapt to different acoustic environments and installation positions.

These settings help compensate for the effects of positioning near walls, in corners or within suitable furniture cabinets, allowing more consistent bass reproduction across different room layouts.

Adjustable Low-Pass Filter and LFE Mode

An adjustable low-pass filter allows the Kube 10 MIE to blend smoothly with compatible main loudspeakers. The crossover can be adjusted between 40Hz and 140Hz to accommodate different speaker configurations.

A dedicated LFE setting allows the subwoofer to integrate with AV receivers and home theatre processors that manage crossover frequencies and bass routing internally.

Flexible Power-On Modes

The Kube 10 MIE provides several power-on options for convenient system integration. Music Sense mode automatically activates the subwoofer when an audio signal is detected, while Always On mode keeps it ready for immediate playback.

A 12V trigger connection allows coordinated power operation with compatible home theatre components.

Sealed Acoustic Enclosure

The Kube 10 MIE uses a sealed acoustic suspension enclosure engineered for accurate and controlled bass reproduction. Unlike a conventional ported subwoofer, its sealed cabinet does not rely on a bass-reflex opening to reinforce low-frequency output.

This construction provides flexible positioning and helps maintain precise bass response for music and cinematic effects. Its compact design allows convenient placement in living rooms, dedicated home theatres and other entertainment spaces.
