Stories begin in 1961, from our UK home, where we have created remarkable award-winning speakers.

Learn about the heart of almost all our speakers. Our pioneering technology developments - the Uni-Q^® driver array.

Explore our patent-pending Uni-Core^® technology redefines the physical space high-performance speakers and subwoofers required to deliver deep and accurate bass.

A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT^™) is a highly complex maze-like structure that eliminates unwanted sound from the rear of driver, resulting in a purer, more natural performance.

Single Apparent Source technology aims to achieve the acoustic ideal of a point source, where low, mid and high frequencies radiate from one point.

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.

In a partnership of two iconic British brands, KEF has created the most immersive in-car audio system to complement the unrivalled driving experience offered by Lotus.

Crossover Frequency

The crossover directs frequencies to the driver best-suited for each particular band. Tweeters (HF drivers) produce high-frequencies but cannot reproduce bass frequencies. Conversely, woofers (LF drivers) do a horrible job of reproducing high frequencies.

In a three-way design there are two crossover points, and in a two-way design there is one crossover point.

For example, with a three-way design with crossovers points at 400 Hz and 2.9kHz, all frequencies below 400Hz (low-pass filter) are directed to the LF drivers. Frequencies between 400Hz and 2.9kHz are directed to the MF driver (band-pass filter) and frequencies above 2.9kHz are directed to the HF driver (high-pass filter).

In a two-way design there is one crossover point: Frequencies above the crossover point are directed to the HF driver and frequencies below the crossover point are directed to the LF/MF driver.

A 2 ½-way design is a hybrid 3-way crossover. Typically there are two LF drivers with low bass frequencies going to one driver and higher bass frequencies going to the other.
