The center channel, which produces all of the vocal track in a film, is ideally placed so that the sound from the actor emanates directly from his or her image. This challenge is most easily accomplished with an acoustically transparent (AT) screen.
Placing speakers behind the projection screen is commonplace in almost every commercial cinema. Our perforation pattern, however, is much more tightly woven with 30,000 half-millimeter sized holes in just one square foot of space.
Slate AT performs exceptionally well as an acoustically transparent material, and it also carries the same ambient light rejecting qualities as its non-acoustic variation. It is truly the best sound and best image.
The effect of the perforated screen has very little attenuation starting at about 1-2kHz and up. Typical impact on frequency response is well within the -3db range with a peak attenuation of -6db at 20kHz. This difference is easily corrected by most modern receivers with room correction. Additionally, many architectural speakers feature a treble compensation switch to adjust for this type of installation.
