I pretty much reused my previous screen frame.

I agree with MM. The contrast is much better than my previous screen. The blacks are much better too. The soundstage is much much better with the AT screen.

@tractng - yes, better to reuse the frame. Give it a shot. You might like it too, just like I did. Keep us posted

You should get about 1.3 gain as compared to under 1.0 with spandex alone. Hope that helps.

Laidback...in case any clarification is needed, Debonaire is referring to S-I-L-V-E-R, a specific paint formula as outlined below. No usable Spandex application has anything remotely close to 1.3 gain.

Using the Liqutex brand results in a lighter S-I-L-V-E-R with less metallic effect. For maximum results use Rustoleum Sterling Silver

MM,

I'm a stoner at times my mind fails me.

For the sake of a non-clouded mind.

At best one might hope for a modest gain up to 1.1 or 1.2 using a Metallic Silver or Pearl or a Combo of both.

That would be all because the AT properties themselves would be affected adversely if enough coating was applied to return more light due to an increase in the actual reflective surface.

None of the "Shiny Metallic Spandex" out there has proven acceptable for use due to Shimmering, Hot Spotting, and other similar effects that are present in most Mfg Screens with gain at / over 1.3. All that without such Spandex even being close to such gain levels.

The above refers to what is the maximum amount of gain one can hope to achieve using dusted paint on Spandex. To obtain the gain levels possible using a solid, opaque surface, so much paint would need to be applied as to saturate the cloth entirely, and therein make any degree of acceptably accurate acoustic transparency a moot issue.

Indeed, if one did achieve a gain of 1.1 to 1.2 on a Spandex surface, that would represent a huge increase compared to the gain one could expect off a raw White or Silver/Gray
