You absolutely positively DO NOT WANT to use a Firehawk screen.
It is designed to improve blacks for digital pj's. It is the worst screen choice possible for a CRT pj.
I would seriously question the credentials of any set up tech that would recommend this screen for use with a CRT pj.
You should use a 1.3 gain white screen such as the Stewart Studio Tech.
If you want some additional brightness, use a curved screen or My perennial favorite the Vutec Silver Star.
If darkened walls are impossible, you should seriously consider a curved screen to improve ambient light rejection.
