The AcousticPro 4K eFinity Series is an acoustically transparent EDGE FREE fixed frame screen. The ultra-thin bezel design reduces the overall footprint and maximizes the viewing area. It utilizes an award-winning AcousticPro 4K front projection material, which has a sheer weave design specifically crafted to improve both audio and visual performance. This screen reduces the light loss while allowing sound to breathe through minimal attenuation. The tight angled perforations negate the formation of the moiré effect which is typically encountered on ost sound transparent screen materials.
