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

As the demand for a more fulfilling lifestyle grows, people are increasingly seeking experiences that enrich their spiritual well-being. Among these, movies have become one of the most popular forms of entertainment. With the ability to enjoy high-definition visuals and immersive sound at home or anywhere, many consumers might no longer feel the need to visit a traditional movie theater. The integration of audio in smart projectors has always been a topic of debate. Some users argue that projectors should focus solely on image quality, while others appreciate the convenience of built-in sound systems. Despite the ongoing discussion, the trend clearly favors integrated audio solutions. Major manufacturers have started incorporating high-quality sound into their projectors, with Cool Music being one of the pioneers. In 2016, Cool Music introduced the S3 model featuring Hivi HIFI audio, which received widespread acclaim. Recently, Cool Music partnered with the renowned American brand AR to launch the R4, equipped with a dual-channel HiFi stereo system. From a design perspective, the Cool Music R4 stands out with its unique metal body and vertical arc structure, differentiating it from conventional flat designs. A detachable real cowhide strap makes it easy to carry, turning this high-performance smart projector into a portable home theater experience. Although 880 ANSI lumens may 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, combined with a seven-glass lens system crafted by optical experts, deliver superior brightness. The result is an output exceeding 1,000 lumens, capable of handling even a 150-inch screen with ease. To enhance the audio experience, AR acoustic engineers opted for two 5W full-range speaker units arranged separately. This configuration ensures a true two-channel sound, optimized through professional placement. Paired with TI audio driver chips, 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 performance, the R4 is powered by a dual 64-bit Mstar intelligent system, paired with 3GB DDR4 RAM and 16GB eMMC storage. This robust hardware ensures fast and stable operation. The custom 10W dual-channel AR stereo provides an immersive listening experience, offering clear and natural sound without any dead zones. Beyond its impressive image quality and features, the R4 makes home theater experiences more convenient and affordable. With a price tag of around 3,000 yuan, it's hard to find a smart projector that matches its performance. That’s why many users and online communities have praised the R4 as one of the most promising smart micro-projectors on the market.
