The 16:9, 180" <b>Epv PowerMax Sonic 2</b> is a UHD and 4K-ready motorized projection screen with acoustically transparent Sonic White projection material. Sonic White is designed to complement in-wall speakers by allowing sound to pass through the material with minimal attenuation, meaning speakers can be placed behind the screen. Featuring a tight, perforated-weave, 0.9-gain fabric, this screen delivers superior video imagery with negligible loss in sound propagation. Additionally, black masking borders enhance picture contrast and absorb projector overshoot.
