Woven sound-permeable picture frame curtain
The YUETMEI sound-permeable screen is made of original German imported materials. Its woven sound-permeable screen is crafted from high-density straight-grain woven glass fiber, with a cross-shaped arrangement ensuring high-quality sound transmission. Its unique structure effectively eliminates the moire (interference stripes) generated when paired with projectors. It allows speakers to be positioned directly behind the screen, achieving unparalleled excellent sound permeability without compromising HD high-definition images. It is suitable for projectors with high resolution, high brightness, and high contrast, providing vivid colors and images with a wide viewing angle. The screen complies with RoHS environmental standards, is UV resistant, anti-static, washable, moisture-proof, mold-proof, flame retardant, and does not age or attract dust over prolonged use. The screen exhibits good physical properties, maintaining good extensibility and recoverability from -40 degrees to +50 degrees. It has extremely low light reflectivity, rich and delicate shading levels, high contrast, bright and vivid colors without being glaring, and a clear depth of field. This imported high-definition sound-permeable screen features high clarity and high contrast, making it suitable for high-definition professional cinema projection.
