Woven sound-permeable drawstring electric screen

YUETMEI's high-definition sound-permeable screen is made of imported materials from Germany. Its woven sound-permeable screen is crafted from glass fibers interwoven in a high-density peak pattern. The unique arrangement of the peak pattern ensures high-definition and high-quality projection while also ensuring smooth sound transmission. Its unique structure is a globally unique new product. Front projection ensures a 3% loss in brightness of the projector, strictly controlling the loss of projection brightness. At a 45-degree angle, sound can penetrate the screen unimpeded. It allows speakers to be positioned directly behind the screen, achieving unparalleled excellent sound transmission without compromising the HD high-definition image. 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 long-term use. The screen has good physical properties, maintaining good extensibility and recoverability from -40 degrees to +50 degrees. It has extremely low light reflectance, rich and delicate shading levels, high contrast, bright and vibrant colors without being glaring, and a clear depth of field. This imported high-definition sound-permeable screen features high clarity and high contrast, suitable for high-definition professional cinema projection.
