    Tractrix horn for tweeter

    Generally a horn high frequency element is acoustically inert regardless if it is metal, wood, MDF or plastic. Material resonances are not significant if properly designed. Musical instruments are built to resonate. Resonant cavities and thin, lightweight construction make this possible, The only danger for a horn is reproducing frequencies too low for the flare rate. Then they honk. This project is very cleverly designed. I would guess it is good for frequencies>1000Hz. Audiophools attach myths to just about everything.

    The textured surface will not be any problem. Sound does not move like water from a garden hose. The air particles bump into adjacent ones to transmit sound. Other than that, they are pretty much stationary. Important is a rounded edge at the mouth and a perfect fitting throat to the driver to prevent diffraction.

    Tractrix horn for tweeter

    Beautiful job. I am looking to print a tweeter (5khz) and midrange (300Hz) horn too. I just need some more experience working with plastics. My day job is teaching people how to use CADCAM software for thermal cutting machines. Are you willing to share the STL file?
