Is there some generally good throw distance for a FP? I am wiring a room for future FP use and need to decide how far back from the rear wall (or future screen) to put the ceiling power outlet and wire outlet. I don't know what FP I will ultimately buy, but the specs on FPs such as the Sanyo PLV-70 all say they work from 4.7 feet on up. I am guessing that putting the outlets about 12 feet back would be good. I would not be using a screen that is more than 6 feet wide and 4 feet high or so because of room limitations. Any thoughts?
