Optimized to the extreme.
The KF8 car audio midrange is the 200 mm (8 in.) midrange designed for SPL competitions. Like the Audiosystem subwoofers, the KF8 features a solid, robust structure and, like all the other SPL Show components, it employs a copper voice coil wound on a two-layer KSV former, for unheard-of thermal and mechanical capability also in extreme circumstances. The cone features a water repellent pressed paper membrane and paper dust caps, both robust and light weight, as well as double-wave damped fabric surrounds to ensure linearity even under extreme conditions, contributing to high SPL scores.
