Review KEF 105/3 Original Oem Mid/tweeter Driver Working Perfectly

Introducing the KEF SP1258 105/3 B160 Mid/Tweeter Driver, a masterpiece of audio engineering designed to deliver exceptional sound quality for music and home theater systems. This mid-tweeter driver is part of KEF's renowned Uni-Q array, a design that sets it apart from other drivers in the market.

The SP1258 driver features a 105mm (4.13 inches) Uni-Q aluminum voice coil midrange unit, coupled with a 19mm (0.75 inches) magnesium/aluminum dome tweeter. The Uni-Q design places the tweeter in the acoustic center of the midrange cone, providing a more accurate and cohesive sound.

The midrange unit's cone is made of an aluminum alloy, ensuring it is lightweight yet rigid. This material allows the driver to respond quickly and precisely to input signals, producing clear and detailed sound. Furthermore, the cone's unique "tangerine" waveguide is designed to control the dispersion pattern of the high frequencies, ensuring a wide yet focused sound dispersion.

The tweeter, meanwhile, is made of a magnesium-aluminum alloy, which is both lightweight and rigid. This material ensures the tweeter can handle high power levels and reproduce the most delicate high-frequency details with ease. KEF's unique "tangerine" waveguide is also used for the tweeter, providing excellent dispersion control and a wide, yet focused, sound dispersion.

The SP1258 driver's powerful neodymium magnet system delivers impressive magnetic force, enabling the driver to handle high power levels with ease. This ensures the driver can perform at its best, even in high-performance home theater systems.

The KEF SP1258 105/3 B160 Mid/Tweeter Driver is designed to be used with high-quality crossovers, allowing you to tailor the driver's sound to your specific system and preferences. Its rugged construction and high-quality materials make it suitable for use in a wide range of applications, from professional studio monitoring to high-end home theater systems.

In summary, the KEF SP1258 105/3 B160 Mid/Tweeter Driver is a versatile and high-performance audio component, designed to deliver accurate, detailed, and cohesive sound. Its Uni-Q design, aluminum midrange cone, magnesium-aluminum tweeter, and powerful neodymium magnet system make it a must-have for audiophiles and home theater enthusiasts looking for the best possible sound quality.
