Verdict

The JBL Bar 300 is a compact, 5.0-channel all-in-one soundbar featuring 260W of total output power and a frequency response of 50Hz to 20kHz. It integrates four 46x90mm racetrack drivers and two 20mm tweeters to deliver virtual Dolby Atmos and MultiBeam surround sound without a separate subwoofer. Main characteristics include an HDMI eARC port with 4K Dolby Vision passthrough, built-in Wi-Fi supporting AirPlay, Alexa Multi-Room Music, and Chromecast, alongside PureVoice technology for dialogue enhancement. Pros include its space-saving design (82cm width), easy room calibration, and strong bass performance for its size. However, notable cons include the lack of upward-firing drivers for true overhead Atmos effects and limited sub-bass extension compared to systems with a dedicated subwoofer.
