I design speaker enclosures for desired acoustic performance, then 3d print and assemble them. I was lucky enough to take Professor Marshall Leach's Electroacoustics class at Georgia Tech. When I worked at Texas Instruments, I used some of that knowledge in working closely with audio customers, as well as writing a whitepaper on acoustic characterization.

Today, I'm still using his textbook when I'm dreaming up these speaker enclosures. I'm a big fan of passive radiators for bass performance while keeping a small size.

I've created four sets of speakers:

I start all designs with selecting drivers based on their electroacousic parameters. From there, I determine an enclosure volume to target a desired performance, and then work in FreeCAD to create a model that can be 3d printed and also meets the target parameters.

Then I move to the 3D printer. I normally print one test enclosure to ensure driver fit (I also print test drivers if I don't have them yet). After making some changes, its off to print.

Depending on the size, they can take a long time. One white enclosure takes 24 hours to print.
