KEF Reference 5 Meta Floorstanding Speakers (Pair)

KEF Reference 5

The KEF Reference 5 Meta Floorstanding Speakers are a pinnacle of audio engineering, offering a three-way bass reflex design that combines cutting-edge technology with meticulous craftsmanship. With a striking dimension of 1350 x 205 x 462 mm and a robust weight of 60.2 kg, these speakers house a formidable array of drivers, including a 25mm aluminum dome High-Frequency (HF) unit with MAT (Metamaterial Absorption Technology), a 125mm aluminum Mid-Frequency (MF) driver, and four 165mm aluminum cone Low-Frequency (LF) drivers. This ensemble delivers a wide frequency range, from a deep 25Hz in typical room bass response to a detailed 45kHz in free field conditions. The crossover frequency of 450Hz and 2.1kHz ensures seamless integration between drivers. These speakers demand an amplifier with a power range of 50-400W, boasting a sensitivity of 88dB and reaching an impressive maximum output of 116dB. With minimal harmonic distortion and an impedance of 4 Ohms (min. 3.2 Ohms), the KEF Reference 5 Meta speakers offer an unparalleled audio experience, showcasing clarity, power, and precision in every note.
