Yes that is the way to go for audio presentation but those perforated screens give up too much image quality. I'm currently using a Vutec Silverstar screen with a JVC RS1 projector and a ND2 filter over the lense, HDMI inputs are through a Toshiba HDDVD XA2. No way I'm using a perforated screen. My centre is below the screen firing up to the seats and sounds great on and just off axis. However, I occasionally notice the dialogue not anchored in the middle of the screen.
