Enjoy the visual experience of the cinema at home as a R4 experience

As the pace of consumption continues to rise, people's pursuit of a meaningful and fulfilling lifestyle has become more intense. Among various entertainment options, films have always been one of the most popular choices for relaxation and leisure. With the ability to enjoy high-definition visuals and immersive sound at home or anywhere, anytime, it’s no surprise that many consumers are starting to question the necessity of traditional movie theaters. The integration of audio in smart projectors has long been a topic of debate among users. Some argue that projectors should focus solely on image quality, while others appreciate the convenience of built-in sound systems. Although opinions differ, the trend clearly favors integrated audio solutions. Major manufacturers now emphasize "high-quality" sound in their products, with Cool Music being a pioneer in this space. Since 2016, Cool Music has been pushing boundaries by incorporating HIFI-grade audio into its devices, such as the S3 model, which received widespread acclaim. Recently, Cool Music partnered with the renowned American brand AR to launch the R4, featuring a dual-channel HiFi stereo system that elevates the audio experience. From a design perspective, the Cool Music R4 stands out with its bold and unique appearance. Its metal vertical arc body is a striking contrast to conventional flat designs, making it both visually appealing and functional. The detachable real cowhide strap adds a touch of elegance, allowing users to carry this high-performance smart projector with ease in one hand. While 880 ANSI lumens might seem modest compared to projectors with over 1,000 lumens, the R4’s innovative RGGB four-channel design, 8A LED package, and overcurrent drive technology ensure superior brightness. Paired with a seven-glass high-definition telecentric lens crafted by optical experts, the R4 delivers an optical performance that exceeds typical 1,000-lumen projectors. It easily handles large screens up to 150 inches with a 1.2:1 throw ratio. To enhance the audio experience, AR acoustic engineers opted for two 5W full-range speaker units, arranged in a separate configuration. This setup isn’t just about doubling the number of speakers—it’s about creating a true stereo soundstage. By using professional speaker units and arranging them strategically, the R4 ensures optimal sound performance. Combined with a TI audio driver chip, DBE dynamic bass enhancement, DSP sound field processing, and 360° Dolby surround sound, the R4 delivers powerful bass and cinematic audio quality. In terms of hardware, the R4 is equipped with a dual 64-bit MStar intelligent system, ensuring fast and smooth performance. Paired with 3GB DDR4 RAM and 16GB eMMC storage, it offers faster data transmission and greater stability. The powerful configuration allows the R4 to operate like lightning, without any lag or delays. Additionally, the custom 10W dual-channel speaker system from AR provides a rich, immersive audio experience with no dead zones. Beyond its technical specifications, the R4 represents a significant step toward making home theater experiences more accessible and convenient. With a substantial boost in audio quality and a price point around 3,000 yuan, it’s hard to find a smart projector that can match its performance. That’s why many fans and tech enthusiasts have already labeled the R4 as one of the most promising smart micro-projectors on the market.
