Hertz SX 690 H — High-Output 6×9″ 3-Way Speakers for Harley Bag Lids
The Hertz SX 690 H is built for Harley riders who want serious rear-stage output. A 6×9″ woofer is paired with a Hi-SPL Mid-Hi unit, a dome tweeter and dome super-tweeter working together on the one axis, so these 3-way 6×9″ speakers fill out your soundstage with strong mid-bass and crisp high-frequency detail all the way out to 24 kHz, ideal for saddlebag lid kits or rear speaker pods.
Key Features
- 3-way coaxial architecture delivering mid-bass punch, vocal clarity and detailed highs.
- Hi-SPL Mid-Hi unit pairing a dome tweeter with a dome super-tweeter, on a 29 mm (1.14 in) tweeter diaphragm with a 25 mm (1 in) voice coil and resettable solid-state protection.
- 94 dB sensitivity ensures strong output even at highway speeds.
- 65 Hz low-end extension for deeper mid-bass response than 6.5″ speakers.
- Weather-resistant design engineered for bag lids and exposed motorcycle environments.
- Rigid pressed-paper cone tuned for natural, controlled midrange at volume.
- Integrated grille-ready design compatible with most aftermarket Harley 6×9″ lid kits.
Why It Works on Harleys
- Rear fill that actually matters — strong mid-bass helps balance front-heavy fairing systems.
- Perfect for saddlebag lids from popular brands (Advanblack, Bad Dad, etc.).
- Wide dispersion helps passengers and rear-stage listeners hear clearly on the move.
- Best paired with 110 to 130 W RMS to unlock full output while staying inside the driver's 130 W continuous rating.
