HERTZ SV 200L

The HERTZ SV 200L was developed for car audio enthusiasts who want to combine maximum volume with precise and powerful bass. As part of the SPL Show Series, this 20-cm woofer impresses with exceptionally high power handling, a highly efficient driver, and a design that operates reliably even at consistently high volume levels.

The large 50-mm voice coil made of pure copper on a heat-resistant KSV carrier, combined with the powerful ferrite magnet, ensures outstanding thermal stability and high control. The vented pole plate improves heat dissipation and helps ensure consistent performance even under heavy load.

For dynamic and precise sound reproduction, Hertz relies on its proven V-Cone® cone geometry. The ultra-lightweight paper cone with cotton fibers enables fast response and natural sound characteristics, while the low-loss rubber surround cleanly controls large excursions. The result is a powerful kick bass with high impulse fidelity and wide dispersion—ideal for SPL- and SQL-oriented vehicle setups.

With its high efficiency, the SV 200L is ideal for high-power amplifiers and performs exceptionally well both as a subwoofer in door installations and in custom-tuned SPL systems.
