I have a woodworking background, so for me, it's very simple just to mask off the speakers, or if possible, to simply disconnect them, and use a HVLP spay gun to re-paint them to any colour I would like.
But I am happy with black
Matt , have you ever seen that wood panel from the 70,s that has been painted, that's what the QS would look like . No way I would ever paint over vinyl, the results would be dreadfull. Besides that they are on the wall and im just too damn lazy to do anything with them.
