The ELCOR ezCinema™ Acoustically Transparent Edge Free Narrow Frame Projection Screen (150-Inch) is a large-format fixed frame screen purpose-built for true home cinema installations where speakers are positioned behind the screen. The acoustically transparent woven fabric allows sound to pass through with minimal loss, enabling a perfectly centred, immersive audio-visual experience. Acoustically Sound Transparent Fabric The screen material is a premium acoustically transparent woven fabric that passes sound through while maintaining a high-quality 4K projection surface. The surface is soft, flat and distortion-free — complying with RoHS, anti-UV, anti-static, cleanable, fire-proof, anti-mould and non-aging standards. Superb off-axis luminance and optimal colour neutrality for reference-grade home theatre performance. Narrow-Edge Zero-Bezel Frame Features a 2.7″ lightweight aluminium frame with a dense black velvet finish that absorbs projector overshoot and increases picture contrast for a polished, theatre-like experience. The tensioned rod and spring system ensures the screen is perfectly flat — ready for cinema-quality presentations in minutes.
