Cool music as smart projection R4 release: Usher in the turning point of 1080p full HD popularity

In recent years, the LED intelligent micro-investment industry has experienced rapid growth, making what was once a luxury—home theater—more accessible than ever. However, even with mainstream 1080p smart projectors available for around 5,000 yuan, many of my friends still find the price too high, calling it the "price butcher." After over a year of development, Cool Music finally launched the R4, a 1080p smart projector priced around 3,000 yuan, marking a turning point in the industry by bringing full-HD projection to the mass market. The R4 is designed with a unique identity, different from other flat-style projectors. It features a rounded cube chassis and a full-metal panel, giving it a more refined and elegant look. The subtle black and grey color scheme allows it to blend seamlessly into any home environment, acting as both an elegant decoration and a powerful entertainment device when in use. The built-in handle makes it easy to move around, adding convenience to its design. In terms of performance, the R4 offers a native resolution of 1920x1080p and a brightness of 880 ANSI lumens. Through advanced optimization of the light source and optical path, the R4 delivers brighter and sharper images on the big screen. Cool Music also collaborated with optical expert Ma Yongzhen to develop a professional-grade lens system, featuring a 7-piece all-glass telecentric HD lens and a precision-milled metal barrel. This ensures superior clarity and reliability in image quality. A true home theater experience isn't just about the visuals—it's also about sound. Unlike many projectors that come with basic speakers, the R4 is equipped with a dual-channel split-band HIFI audio system developed in collaboration with AR (Acoustic Research). This setup delivers cinema-grade surround sound, providing an immersive audio experience that matches the visual quality. One of the standout features of the R4 is its lens slide design, which allows users to switch between movie and music modes simply by sliding the lens cover left or right. This feature enhances the versatility of the projector, making it ideal for music lovers who want to enjoy both visual and auditory experiences. Powered by Mstar’s latest dual 64-bit intelligent system with a 3GB RAM and 16GB storage configuration, the R4 runs smoothly and efficiently. It also includes a special focus camera, a high-precision voice coil motor, and a copper gear reducer, ensuring sharp and accurate focusing during use. Other notable features include automatic trapezoidal correction, wireless screen mirroring, support for 4K and 3D content, and electric/auto focus. The R4 also comes with standard interfaces such as HDMI and USB, making it versatile for various applications. With a starting price of 2,799 yuan, the R4 represents a significant step forward in making 1080p full HD projection affordable and accessible to more people. As this product enters the market, it signals a new era where every family can enjoy a private cinema experience at home.
