The following audio measurements were conducted in a 128 cubic foot anechoic chamber specifically designed for testing audio transparent materials.

The speaker used for testing was a Genelec 1031A Bi-Amplified Monitoring System
(THX ® pm3 certified).

Measuring instruments included a Bruel & Kjaer 4191 microphone with a Bruel & Kjaer 21610 Measuring Amp and Praxis. Also used was a consumer vacuum chamber calibrated EMM8 electret condenser microphone with R+D and REW software which yielded similar results.

The Speaker Baffle was placed 6" from the screen material and the head of the microphone was one meter from the speaker baffle with the screen material in-between.

This first graph shows the Speaker (Light Blue Line) and a Perforated Screen (Green Line)  

Note the heavy amount of dips and peaks throughout the trend of the speaker line.

This would require a good amount of EQ on each channel to level this out.
Combfiltering would still be present after EQ.

This second graph shows the Speaker (Light Blue Line) and SmX CineWeave™ HD (Pink Line)

Note how the CineWeave follows the trend of the speaker line.
EQ is not needed and combfiltering will not be audible.
