KEF Kube 15 MIE

The KEF Kube 15 MIE is the largest and most powerful model in the Kube subwoofer range, engineered to deliver deep, precise, and dynamic bass for high-performance audio and home theater systems.

At its core is a 15-inch (380 mm) front-firing driver powered by a 300W RMS Class D amplifier. Combined with KEF's Music Integrity Engine® (MIE), its advanced DSP processing optimizes driver performance, improving bass extension, accuracy, and dynamic response while maintaining exceptional control, even at higher output levels.

Its sealed cabinet design provides tight, accurate bass reproduction while offering flexible placement options, including inside custom cabinetry. KEF's iBX Intelligent Bass Extension technology further enhances low-frequency performance, delivering deeper bass at different listening levels.

The Kube 15 MIE also features KEF SmartConnect, which intelligently detects mono or stereo input signals and automatically adjusts subwoofer volume for seamless integration with existing audio systems. Multiple connectivity options, including RCA and speaker-level inputs, make it compatible with a wide range of amplifiers and receivers.

For additional installation flexibility, the optional KW1 Wireless Subwoofer Adapter Kit allows wireless connection without compromising audio quality. Three room placement EQ settings and multiple power modes help optimize performance for different environments and listening preferences.

With a maximum output of 116 dB and frequency response extending down to 20 Hz, the Kube 15 MIE delivers powerful, room-filling bass that brings music and movie soundtracks to life.
