The Sonic AT8 ISF surface is designed to work with all lens throws to provide ISF certified color accuracy and wide diffusion uniformity for projected images, all while offering sonic transparency to hide in-wall speakers. A multilayer ultra-fine knit design negates the moiré effect common to acoustically transparent screens and allows for compatibility with UHD projectors. The SE135H-AT8-ISF assembles easily on a 2.2" aluminum frame which is wrapped by hand in black velvet to prevent projector overshoot. A spring and tension rod system for attaching the screen material provides a smooth and even surface. All hardware is included, and the lightweight split-frame design makes for easy shipping and delivery to install sites. Additionally, a sliding wall mount is included to ensure proper alignment with your projector.
