    Will the screen be blocking the sound enough to affect quality? The screen material is obviously much thicker than the fabric grill used on the speaker itself.

    Thanks,

    Yes, you’ll lose high frequencies. Screens are typically perforated to allow some high frequencies to pass. But even then you’ll need to electronically boost the highs to make up for the loss.

    Do you mean turning up the treble? Also, where do you guys put your center speaker? Behind or in front of the screen, top or bottom?

    Thanks,

    You might look into an acoustically transparent screen. They're out there though they may not be inexpensive.

    To place a speaker behind a screen, you need to use a screen intended for this application. The costs can vary greatly ranging from some of the lesser knowns to Stewart MicroPerf all the way to Screen Research's solution. The impact on the sound is less with the MicroPerf and most especially with the Screen Research, but others offer good quality 'perf screens as well. In many rooms the placement differences of the L/R vs. the center make for equal or more variation than that of the screen. While it does have some effect on the picture, placing the center channel behind the screen (ideally at 1/2-2/3rds height), usually makes for a much more convincing and engaging presentation.

    Some DIY screens are fairly nicely acoustically transparent..

    I'm using a light gray cotton screen, stretched, with a loose black terry backer (about an inch off of the back) as a light trap. Very minimal impact on the sound - at least, I've got far worse problems that any impact caused by the screen are going to be so minimal as to not exist...
