This is the best sounding and loudest Harley lower fairing speaker kit you will find. If you are looking for the very best this is the kit for you. This kit comes with steel replacement speaker grills with Velocity RZ75H horns mounted in them for you. The RZ75H is by far the very best compression horn tweeter on the market. It has a wider frequency response due to its dual stage horn flare and 12db passive crossovers instead of the industry standard single stage flare and 6db per octave crossovers. The included Velocity RZ65 Neo 6.5” midrange drivers are also top of the line and produce a better mid-bass punch and smoother upper frequency response than all other 6.5” speakers available. 


  • 6.5” ½ inch thick spacer required for some lower fairings that have a ½ inch recess. 
  • Liquid cooled lower fairing adapters will need a small amount of clearancing for the diameter of the mid-woofer but basket depth is not an issue.
  • Tweeter can be connected to the mid-woofer and the passive crossover loaded inside of the lower fairing in lowers with space inside but other lowers will require the passive to be located in the upper fairing. In thosae cases a dedicated speaker line will need to be run from the amplifier down to the lower fairing for the tweeters. 
  • Fully active 4 channel speaker wire harness that is plug and play with the Velocity 8 digital sound processor is available here.
  • Compatible Year - 1998+
  • Compatible Model - Street Glide, Road Glide, Ultra Glide, Electra Glide, Road King
