HERTZ (SV165.1) 6.5" 400W PEAK POWER HANDLING 4-OHM IMPEDANCE SPL MIDRANGE SPEAKERS (PAIR) 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. FEATURES: High magnetic permeability plates provide constant, even flux. High density flux ferrite magnet, for top SPL performance. Double layer copper voice coil, wound on KSV former; for excellent thermal and mechanical capability. High current, tin-plated terminals. Damped fabric surround; for maximum lightness and extreme SPL.
