The Hertz Cento CX165 is a two-way 165 mm coaxial car speaker engineered to improve OEM placement performance with optimized off-axis dispersion. It uses a 24 mm Tetolon dome tweeter and an SPP-M semi-pressed paper-mica woofer cone to prioritize musical detail and damping.

Hardware includes a 13 mm mobile coil tweeter cooled with ferrofluid, an RHFC angled directable tweeter faceplate, a 25 mm woofer coil with aluminum former, and a high-density ferrite magnet with a three-spoke basket and rubber magnet cover. The speaker is designed for 165 mm factory openings and connects to standard vehicle speaker wiring; grille available as an optional accessory.
