Built for high-output setups, the Hertz SX 690 NEO.1 is a 6x9 3‑way SPL coaxial speaker pair designed to stay clear at volume. It combines a pressed‑paper cone treated to resist water/humidity and UV exposure with a compact neodymium motor to support strong efficiency in a lighter, smaller package. High frequencies are handled by a 1.4‑inch dome tweeter plus a 1‑inch dome super tweeter, and the HF section is protected by a resettable solid-state circuit.
In real installs, the 4‑ohm impedance and 94 dB sensitivity make it easier to reach strong output with common amplifiers, while the published frequency response of 65 Hz–24 kHz supports energetic midbass punch with extended top-end detail. Mounting depth is 85 mm (3.35 in), so it works in many rear deck, door, and bag‑lid style locations—always confirm cutout and clearance with the official dimensions before ordering.
Unlike many reseller listings that leave accessories unclear, this model includes the MPG 690 grille, helping protect the speaker when mounted in more exposed locations. For best durability, use solid mounting, clean amplification, and filtering appropriate to your system (especially if you run a subwoofer).
