In my effort to make a handful of videos using my new favorite video editing software, DaVinci Resolve, I thought one on building this passive speaker would be appropriate.
My wife listens to music and watches videos when she's in the kitchen and usually props her iPhone somewhere on the counter. I decided to make a passive speaker so the sound would be directed toward her and so that her phone will be held in properly in landscape format for viewing videos.
Today I made a short video about building this speaker (posted below).
