The Hertz K170 is a component speaker set pairing a 24 mm neodymium PEI-dome tweeter with 6.7in pressed-paper woofers to deliver detailed highs and solid bass. The kit includes tweeter mounting accessories and DIN-size woofer baskets for OEM-style installation.

Key engineering features include an annular acoustic lens for improved off-axis imaging, V-cone woofer design, a 25 mm pure copper woofer voice coil driven by a high-flux 80 mm ferrite magnet, and a 6dB/Oct crossover integrated on the tweeter wiring for simple OEM upgrades.
