Center speaker question

Hey guys I am finishing my basement and trying to decide a few aspects. I have a 5.1 speaker package purchased with in wall LCR speakers. I plan on an UST projector. I would like to put the center in wall speaker behind the screen, But looking at acoustically transparent screens they say that they are not compatible with UST projectors. If this is the case will the center speaker still function well behind an ALR screen? I might not have enough room beneath the screen.

Thanks for the recommendations.
