Music Integrity Engine®

The mastermind 

KEF’s Music Integrity Engine® (MIE), a proprietary suite of in-house coded DSP (Digital Signal Processing) algorithms, is the mastermind behind our wireless HiFi speakers and subwoofers. Each unique MIE is precisely tuned to allow all components within the individual wireless HiFi speaker or subwoofer to work in perfect harmony, elevating the overall performance for remarkable integrity, detail, and accuracy of sound.​

Fast. Precise. Accurate.

MIE executes incredibly fast calculations to analyse input signals, unlocking each product's full potential to deliver unparalleled precision. Whether it is the phase correction feature that fixes inherent timing issues of the wireless HiFi speakers, or the iBX Intelligent Bass Extension feature that enables our subwoofers to deliver deeper bass and greater dynamics, the result is an immersive experience that surpasses expectations.​

Engineered to perfection

At KEF, we always push the technological boundaries in our mission to create the best possible sound. While typical DSP solutions entail a generic application, MIE algorithms are specifically tailored for each product by our Research & Development team at Maidstone, UK. Building upon an already excellent acoustic foundation, these bespoke MIE algorithms bring each product to the very pinnacle of its capabilities.​

Single Apparent Source
Technology

Single Apparent Source technology aims to achieve the acoustic ideal of a point source, where low, mid and high frequencies radiate from one point. Perfectly calibrated drivers that cover the entire bandwidth of the loudspeaker are configured so that all frequencies appear to radiate from one single point. The result is noticeably more precise imaging and highly accurate sound across a wider area.

Uni-Core® 

KEF’s innovative, patent-pending Uni-Core® technology redefines the physical space that high-performance speakers and subwoofers require to deliver deep and accurate bass. Through exceptional engineering and creativity, KEF’s engineers have revolutionised the traditional force cancelling arrangement with a Uni-Core® design that delivers deeper bass from ultra-compact cabinets.

Metamaterial Absorption Technology

A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.
