JVC RS4500 | ST130 G4 135" | MRX 720 | MC303 MC152 | B&W 802D3, HTM1D3, 805D3, 702S2 | 4x15 IB Subs
Where do you see that?Stewart's online specs says G4 is a lower 1.1 gain
It shows 1.3 gain here: https://www.stewartfilmscreen.com/en/materials/studiotek-130-g4 under "specs".
I realize gain is always only rated at the 0 degree angle.
Then in the downloadable spec sheet:
https://www.stewartfilmscreen.com/Files/files/Support Material/Material Data Sheets/StudioTek 130 G4.pdf
It shows the same 1.3 and also says: "unmatched by competing gain screens. StudioTek 130 G4 is thirty percent brighter than
a matte white screen surface"
