My goal is to make the best drop in replacement horns available for Klipsch heritage speakers. 

See why symmetric horns are going to change the way you listen to music.

All Fastlane horns are 3D printed in a temperature controlled environment to improve strength and durability. Horns are printed  .3 -.5 inches thick with 20% gyroid infill to minimize ringing. Larger horns are gusseted for additional strength.

Ender 5 Max  - with mods

I have tried a couple different printers, but 

Creality printers work right out of the box.
