Screen Innovations (SI), which is distributed in Australia by Network AV, has announced that both Slate and Pure screen materials are now available in their acoustically transparent Micro Perforated or MicroPerf material. Slate screen material has become a staple for home theatre enthusiasts and integrators alike, providing the projection industry with a moderately-priced ambient light rejecting screen.
“We created MicroPerf to give our customers the best of both worlds; the best picture and the best sound. Pure and Slate have solved the problem of image quality with the sharpest image reproduction in the market by managing the texture pattern down to 9 times finer than standard white or grey materials, maintaining image uniformity. Merging Slate and Pure with our MicroPerf technology has truly created the best of both worlds, picture and sound. Imagine hiding your favourite LCR speakers behind a massive Zero Edge screen with our popular Backlighting, even with the lights on thanks to Slate’s ALR properties,” said SI CEO Ryan Gustafson.
Slate MicroPerf has been a long-term SI goal as part of its vision that the screen should not be a distraction for the viewer, instead adding to or even improving their experience.
“Hiding your speakers behind the screen is another way that this is accomplished—allowing the sound to improve your viewing experience but not detract from your visual experience. It has not been easy. Micro Perforating is difficult in its own right, but working with a 106” tall material is nearly impossible. We are perforating over 28,000, 0.55mm holes for every square foot, clearly a daunting task,” said SI chief of technology Tom Nugent, who led the project.
Tom explained SI’s MicroPerf was sent to the laboratory of an industry-leading speaker manufacturer for testing, with excellent results showing very few acoustic ramifications over the full audio frequency spectrum.
“The effect of the MicroPerf screen has very little attenuation starting at about 1-2kHz. 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,” said Tom.
MicroPerf is available to order now in SI’s Slate and Pure screen materials, which can be configured on all the company’s screen form factors such as Zero Edge, Zero-G, Fixed and Motorised.
