|From the Draper web site:
AT1200 The most innovative and versatile acoustically transparent screen material available. Superior in gain performance to standard matt white material and does not require tensioning for flatness. Acoustical properties comparable to the finest speaker grille cloth. Washable, flame and mildew resistant. Peak gain 1.3
- Is it 1.2 or 1.3 gain?
- Is a 1.3 gain perforated screen equivalent to a 1.3 gain non-perforated screen? In other words, when they say a perforated screen is 1.3 gain are they taking the holes into account?
