    When setting up your HC, should the screen be 'flush' with your speakers? Or is it OK to have the speakers a couple of feet in front of the screen?

    I'm asking this, because I'm wondering if I should screw the screen to the wall or not. Obviously if I do, then the Left, Centre and Right speakers will stand before the screen.

    In an ideal world you would have your speakers flush with the front of the screen. But in most cases this is not possible. Haveing them up to 1ft in front of the screen is not a problem so long as the sound appears to be coming from the appropriate places at the right times. Make sure you have your delay times and channel balances set right.

    What speakers are you using?

    My AV Receiver is the Sony STR-930, my center speaker is a B&W CC6, and my fronts are the older B&W 600 series.

    I just measured the front of the speakers to the front of the screen, and it's 18".

    It doesn't sound like a problem to me. Pur a film on and see if it sounds right.

    How would you use the Delay settings to compensate for the speakers being in front of the screen?

    Your speaker delay settings are to make sure all your speakers are woring in time with each other. To get a sound signal in sync with the picture you would need a global dealy over all the channels. This is only really needed if you have extra video processing in your system.

    Unless you can see a huge lip sync problem I would not be worried.

    Sound travels at about 330m/s, so each 33cm that your speakers are in front of your screen will require a 1ms delay. 18" is about 1.5X that, so a 1.5ms delay would be appropriate. As Richard says, though, you probably won't notice something this small.

    Cheers,
    Liam

    I understand, thanks. Makes perfect sense!

    When I eventually get my pj, I will have a listen, and play about with the delay settings if need be.

    Thanks a lot, it's put my mind at rest, now I can go ahead and screw that damn MDF to the wall.
