I wanted to make this really, really bad, but I couldn't do it myself since I don't know how to use the circular saw and I don't know how to measure and angle the crown moulding the right way. I had Jacob help me!
I put regular sized computer speakers (about 5-6 inches in height) on each side of the mp3 shelf thingy. I crazy-glued the speakers down (so they wouldn't move around). I made a hole in the back for the cord (for the outlet). I used black net stuff (for latch and hook or whatever its called)-- use the really thin kind.
