KEF Kube 10 MIE 10-Inch Powered Subwoofer in Black (Each) - SP4074B0CA

KEF SP4074B0CA Kube 10 MIE 10-Inch Powered Subwoofer in Black (Each)

The KEF SP4074B0CA Kube 10 MIE 10-inch front-firing active powered subwoofer pairs a sealed cabinet and long-throw driver with a cool-running 300W RMS Class D amplifier. Its 24Hz-140Hz (+/-3dB) response and 111dB maximum output deliver deep, controlled low frequencies, while Music Integrity Engine DSP and iBX Intelligent Bass Extension coordinate the system for greater depth, dynamics and precision at any listening level. Three room-position EQ presets, KEF SmartConnect, RCA and speaker-level inputs, and multiple power modes make the Kube 10 MIE easy to integrate for movies, music, TV and gaming.

For listeners choosing a powered subwoofer with flexible placement, an expansion port supports the optional KW1 wireless subwoofer adapter for signal transmission without a cable.¹

Key Features

Music Integrity Engine and iBX Bass Extension

KEF developed the Kube 10 MIE's proprietary DSP algorithms specifically to manage how its components work together. The system rapidly analyzes incoming audio, while iBX Intelligent Bass Extension reaches deeper and maintains bass detail across different listening levels.

10-Inch Long-Throw Driver and 300W RMS Power

The front-firing driver combines a large cone area with high excursion to move more air and increase output in the lowest frequencies. A 300W RMS Class D amplifier supplies the needed power with an efficient, cool-running design.

24Hz Extension and 111dB Maximum Output

A 24Hz-140Hz (+/-3dB) frequency range gives soundtracks, games and music a substantial low-frequency foundation, while maximum output reaches 111dB. The variable 40Hz-140Hz low-pass filter and LFE mode help the subwoofer blend with the rest of the speaker system.

Three Room-Position EQ Presets

Placement-dependent equalization makes it easier to tune performance for the actual room. Choose the appropriate preset when the Kube 10 MIE is positioned in cabinetry, against a wall or in a corner to maintain consistent bass response.

KEF SmartConnect and Flexible Inputs

KEF SmartConnect detects whether the source uses a mono or stereo input and adjusts gain for that connection. RCA phono sockets and speaker-level inputs allow the subwoofer to work with a wide range of amplifiers and audio systems.

Auto Wake, Always On and 12V Trigger Modes

Select music-sense Auto Wake for activation when an audio signal appears, Always On for immediate readiness, or 12V trigger control for coordinated startup in an integrated system.

Mid-Sized Sealed Design

As the mid-sized model in the KEF audio range, the Kube 10 MIE balances substantial bass capability with flexible positioning. Its sealed cabinet and minimal, contemporary exterior are designed to work with the room acoustically while blending with the decor.
