Not being able to leave well enough alone, I’m toying with adding more show to my basement disco setup.  I decided to pick up a couple NeoPixel rings (12 LED version) and integrate them into the music-reactive mode.  These will be slotted in the open space at the bottom of the speakers near the sub port (see link below).   This was designed to fit for this NeoPixel Ring.  If you want to print some, download the STL files.
