Anyone done this? If so, what have you used and what were the results? I'm thinking of making my own simple mounting shelves out of heavy duty brackets and a sheet of thick MDF, perhaps 18 inches wide so that I can get the speakers as far as possible away from the wall. I am a bit worried by the fact that they are rear ported and even though AE website says they are designed for stand/shelf mounting I am worried about the rear port and proximity to the wall. Grateful for any feedback.
