Hertz Fairing Combo Kit - Stage1

This is a truly amazing Harley-specific speaker. Hertz hit it out of the park with this design. The large oversized 1.4-inch tweeter is the loudest non-horn tweeter we have ever tested and it is louder and better sounding than many stand-alone horns. The woofer of this speaker is a pro audio design that has been optimized for use in Harley applications. Designed to perform in the fairing, tour packs, and lower fairings these woofers deliver clarity and loudness for even the largest scale systems.

1. Nature-proof high stiffness pressed-paper cone featuring innovative water/ humidity resistant and anti-UV treatments.

2. Durable Extreme SPL performance in a compact size & light-weight thanks to the N38 H Neodymium grade magnet.

3. Unparalleled power handling delivered by the double layer copper voice coil, wound on polyamide former.

4. Hi-SPL 1.4” Neodymium magnet PEI dome tweeter with resettable solid-state tweeter protection circuit.

5. Double faston terminals allow daisy-chaining of multiple units and provide compatibility with most common motorcycle connections.
