The Hertz Dieci DSK130.3 is a two-way car speaker component set that uses a V-cone profile woofer to improve off-axis response and deliver detailed mid to high range performance. The woofer employs a TPU surround to maintain linear excursion and reduce unwanted resonance at higher excursion.

High-performance components include a neodymium motor assembly and a PEI tweeter membrane for extended high-frequency reproduction. Passive filters are mounted on the supplied connection cables and the kit ships with accessories to simplify installation and connection to factory or aftermarket systems.
