Hertz Neo Woofer & Compression Horn Mount Combo 14+ SPK-14HZ-2565


All New Hertz SV 165 Neo Woofer with Better Bottom End and the Mighty ST 25A Neo Compression Horn Tweeter Combo

Get the latest and the greatest with the all-new Neo woofers and tweeters. We worked extensively with Hertz during the development phase of these speakers. We love the regular SV 165 and ST 25A speakers but we thought that a neo magnet (stronger, lighter, smaller, higher focus) would be a nice addition as well as a better bottom-end response. Hertz made good on our requests and delivered a speaker that truly outperforms the best-selling fairing woofer on the market (SV 165.1 iron magnet). 

They asked what we wanted to see in a speaker and we told them.
  • Waterproof
  • Treated for UV Exposure
  • Improved Bass Response
  • Premium Neo Magnet
  • Higher Resonant Design
  • Smooth Frequency Response 
  • Efficient, Loud, Extreme Power Handling 

They combined that list of demands with their own expertise and high manufacturing standards to produce a truly amazing speaker.

Now Includes the All-New Hertz ST25A Neo Compression Horn Tweeters with Billet Grille Bezels & Steel Grills!

The new Neo (A) version of the ST25 horns comes with a number of improvements over the old (but legendary) ST25 horns. They now include plug-and-play crossovers, rubber locking rings, replaceable diagrams that do not require soldering, and steel mesh grills. It offers superior performance with the use of Neodymium N38 H for the motor units and a FEM (Finite Element Method) optimized driver/horn design. 

         Hertz ST25K Neo Assembly

New Low Depth Motor Opens up Many New Mounting Options That Just Was Not Possible With the Old ST25 Horns.

The ST25K Neo horns are lighter weight and have a shallower mounting depth yet they still have the same horn flare for that one-of-a-kind Hertz sound. The new smaller magnets are stronger than the old magnets on the original ST25s. 

New Replaceable Voice Coil/Diaphragms  

Neo ST25 horns now feature a removable diaphragm that can be swapped out without any soldering! This is handy for guys that push their systems way past reasonable limits when at competitions. 

Note: Crossovers not included. Crossovers must be used. You can find them here. Grills not included. You can find those here

Finally, a Great Way to Add Horns to Any '14 & up Harley Fairing without Modifications!

The included horn mounting kit allows you to replace the two small gauges on a Street Glide, Road Glide, Electra Glide, or Ultra with a pair of Hertz ST25A Neo horns. The kit uses the factory hardware so that no modifications are required.

There is no better way to get loud clean highs from your system than adding compression horn tweeters.

Fuel Gauge

Fuel Range
Losing the fuel gauge is no big deal because all of the '14 & up bikes have a fuel range feature built into the speedo. The range feature is much more accurate than the basic fuel gauge anyway. Simply tap the mode switch on top of the clutch and range is displayed.

Voltage Gauge

Optional Voltage GaugeAmerican Hard Bag Harley Replacement Volt Gauge

Optionally you can replace your cigarette lighter port with a digital voltage gauge. We offer a waterproof model with two USB ports built-in. Connections are simple and no wires need to be run because it uses the same circuit as your cigarette lighter port. When the bike is off the voltage gauge goes black and hides.


Turn Signal Indicators

Turn Signal Indicators

We offer an optional turn signal kit that consists of two small green 12V LEDs that can be placed up near the windshield. On the Road Glides inside of the air-vent works nicely. You can't see them until they are on and they are impossible to miss when they are on.
