Picked up a Radion this week and needed a mounting method. Wanted a removable mount and this what I came up with. I had most of the materials from some previous projects... The foam board is dyvinecyl (spelling?) meant to accept resin. Cut the board, samdwiched with fiberglass,lots of trimming & sanding and some rattle can paint. Could have spent more time making it nicer up close but it works for meDance
