By purchasing the plans you will automatically receive the required assembly and detail drawings to construct the speaker. Also included is the 3D CAD file to 3D print the ES circular horn as well as the passive crossover schematic. 

Required to build (included):

  • 3D print ES circular horn using the provided .stl file. or CNC machine 
  • Construct cabinet using provided assembly and detail drawings.
  • Construct passive crossover (requires soldering) using provided schematic 

Features
