Your budget and the fact that you want it to hang on a screw (which means the speaker can’t be more than a few pounds) limits the playing field considerably. The Polk OWM3 fits the bill. You might also considered a used pair of the vintage Realistic Minimus 7 from ebay. It came in a variety of colors like wood grain, black, silver and white. I've been using a pair for surrounds in my bedroom system for a number of years.
