Really cool! How does the sound work? Is it listenable?

This was a very good idea! I did this with some old speakers I have, and have two matching halves now. You should really describe how you cut your tennis ball in half. it looks wonderful! Mine wound up with all sorts of jagged edges all over it from where I botched the knife work.

Very cool Idea, but "mono stereo" is a bit of a misnomer.
