My GrayHawk screen should be in the truck on its way to VA...I'm getting excited to get it. http://www.avsforum.com/ubb/smile.gif

One question, I thought the GrayHawk gain was .85, but the Stewart web site lists the gain as .95. Is that right?

The gain for the regular screen is .85. They increased the gain to .95 for the perforated sceen because you lose some gain due to the holes. If you have a micro-perf then the gain is going to be higher. If you do not it will be .85

Never become so involved with something that it blinds you.

Ben,
Can you please email me you findings when you get your screen set up? I live in Sterling also and I am debating on which screen to get. Let me know what you think.

TIA

OK, if I am planning to use a Grayhawk, and a perforated screen, do I need to deduct any brightness for the perforations, or does .95 consider that already??

<scratching head> ??

Usual perf loss is said to be 10%.Thus perceived brightness is same(.85 approx for both.)

The rated gain of the non-perfed screen is indeed .85 for the Grayhawk. However, in testing they have found that it is actually closer to .90+. Stewart quotes conservative gains so that if it happens to be more you will get a bonus. Some other companies quote higher than true gains for their screens to hype them up more. Another reason Stewart is the best!

Thanks!
