Hertz SX 165 NEO — High-Output 6.5″ Coaxial Speakers for Harley Touring
The Hertz SX 165 NEO delivers clear, punchy midrange and crisp highs that cut through wind, pipes, and highway noise — exactly what Harley riders expect from a serious audio upgrade. With a lightweight neodymium motor, weather-ready construction, and high efficiency, these are built for fairings, lowers, or Tour-Pak locations.
Key Features
- High-efficiency SPL design — 96.5 dB sensitivity gives strong output with moderate amplifier power.
- Lightweight neodymium magnet reduces mass on the fairing and improves mounting flexibility.
- Wide 100–20,000 Hz response for a full mid/high presentation suited to motorcycle environments.
- Weather-resistant build designed to handle rain, washdowns, heat and vibration.
- Rigid pressed-paper cone with treated surround delivers controlled midrange at high volume.
- Integrated coaxial tweeter — a 35 mm (1.4 in) neodymium PEI dome with 28 mm voice coil and resettable solid-state protection — keeps imaging stable and installation simple.
- Double faston terminals make daisy-chaining and multi-speaker layouts straightforward.
Why It Works on Harleys
- Excellent clarity at speed thanks to high sensitivity and a strong upper-mid presence.
- Neodymium motor means less weight on the fairing compared to ferrite-based speakers.
- Ideal for factory locations in Street Glide, Road Glide, Ultra Limited and Tour-Pak pods.
- Performs best with proper crossovers — Hertz rates the 100 W continuous power handling with a 150 Hz high-pass filter at 12 dB/octave, so set the crossover there for full rated power and long-term reliability.
Recommended Power
- Amplifier Power: up to 100 W RMS (do not exceed the driver's 100 W rating)
- Minimum: 60 W RMS
- High-Pass Filter: 150 Hz @ 12 dB/octave — Hertz's rated condition for 100 W continuous
- Important: crossing over lower than 150 Hz increases cone excursion on a driver with only 1.5 mm Xmax, so the power the speaker will safely accept drops as you lower the crossover point. Reduce amplifier power accordingly.
Fitment
- Designed for Harley-Davidson Touring motorcycles
- Suitable for upper fairings, lower fairings, and Tour-Pak pods
- Direct replacement for most 6.5″ factory speaker locations
- Adapter rings available if required (contact us for guidance)
