Hertz SV 165.1 midrange speaker (165 mm).

Hertz SV 165.1 (SPL SHOW series) midrange speaker 6.5" (165 mm)

The SV 165.1 car audio midrange can be employed to build systems with tremendous impact. 
Like the SX subwoofers, the SV 165.1 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.
