Ted Kessler published overview and testing of his fully 3d printed speaker.

It doesn't sound great, but hey, it is not the reason it was made ...

This is an experiment in inventing a new tone as a tool for musicians. Speakers were invented between the 1860s-70s and have more or less been constructed with the same materials since. There was something interesting to me about reproducing a classic design with a cutting-edge technology and modern materials, so I did that.
As the speaker's utilitarian and scientific roles have been fulfilled for decades and are now used as art tools, I wanted to treat them as art tools.
The printed parts were done on a consumer-level Rigidbot FFF printer.
There's still development to be done on this project and I look forward to it!
