All-in-One 5.0 Channel Sound Bar

The JBL BAR-300-MK2 is a single-unit sound bar delivering a 5.0 channel configuration with Dolby Atmos support. It uses MultiBeam 3.0 technology to project immersive audio around the room without requiring separate satellite speakers. PureVoice 2.0 enhances dialogue clarity so speech remains intelligible during complex soundtracks. The system integrates racetrack drivers and tweeters behind a black finish.

Ideal for Streamlined Home Cinema Setups

This sound bar suits viewers who want a simplified 3D audio experience from one component and value automatic room calibration via the JBL One App. It fits users who prefer controlling playback through the included remote or smart device integration. Buyers seeking a traditional separate speaker layout with a dedicated subwoofer or rear channels should consider alternative systems. The all-in-one design does not support adding wireless surround modules.

HDMI eARC with 4K Dolby Vision Passthrough

The single HDMI output supports enhanced Audio Return Channel and passes 4K Dolby Vision and HDR10+ video signals to a compatible display. This connection carries lossless audio formats from the TV back to the sound bar while preserving high dynamic range video quality. Optical, USB and Bluetooth inputs provide additional source options for music streaming or legacy devices. The HDCP 2.3 compliance ensures compatibility with protected 4K content streams.

Questions about this item

How do the five channels in the JBL BAR-300-MK2 translate into drivers inside the soundbar?

The soundbar uses five 42x80 mm racetrack drivers and four 0.75-inch tweeters to create a 5.0 channel layout without a separate subwoofer.

What does the 50 Hz low-frequency figure mean for movie bass in a living room?

The 50 Hz lower limit means deep rumbles and explosions are reproduced from the built-in bass ports, though very low sub-bass below 50 Hz will not be heard.

What does the HDMI eARC port with HDCP 2.3 allow when connected to a 4K TV?

The eARC connection passes lossless Dolby Atmos audio from the TV to the soundbar while also supporting 4K Dolby Vision and HDR10+ video pass-through.
