The Hertz SX 165 NEO is a high-efficiency 6.5-inch coaxial speaker set built for systems where volume, durability, and straightforward installation matter, especially in motorcycle fairings, UTVs, and other noisy, open-air environments. With a 4‑ohm load and strong sensitivity, it’s designed to get louder with less power than many conventional speakers, helping you keep clarity at speed.

This is a purpose-driven SPL coaxial: a rugged midrange foundation paired with a wide-dome high-frequency section so lyrics and attack stay present without needing a separate tweeter mount. The treated paper cone is engineered for resilience against moisture and UV exposure, and the compact neodymium motor design supports strong performance in tight spaces.

Install confidence comes from the details: confirm your mounting depth and cutout before ordering, and plan your crossover correctly—these speakers are intended to be used with a high-pass filter for best protection and the cleanest output. If your build is exposed, note that grilles typically aren’t included for this model, so consider adding protection based on your mounting location.

  FAQs
  
  

  Q: Do these include grilles?
  A: Official materials don’t list a supplied grille for this model, and many retailers note “grilles not included.” Plan protection if your install is exposed.

  Q: What crossover/high-pass should I use?
  A: The tech sheet states the continuous power spec with a high-pass filter at 150 Hz (12 dB/oct). Use a proper high-pass setting to reduce distortion and protect the speaker.

  Q: Will these work on a motorcycle fairing setup?
  A: They’re commonly selected for motorcycle/UTV installs because of their high efficiency; always confirm depth, cutout, and mounting hardware for your specific fairing.

  Q: Do I need an amplifier?
  A: You can run them on moderate power, but an amp with clean headroom typically improves clarity at high volume; avoid clipping and tune gains correctly.
