All-in-one 5.0 channel soundbar

The JBL BAR-300-MK2 is a 5.0 channel all-in-one soundbar that delivers 260W total system power through four 46x90mm racetrack drivers and two 0.75" tweeters. MultiBeam 3.0 and Dolby Atmos create a 3D surround field without separate rear speakers. PureVoice 2.0 enhances dialogue clarity across movies, music and TV.

5.0 channel all-in-one architecture

The single-bar 5.0 channel design means no external subwoofer or satellite speakers are required to reach the stated channel count. Built-in bass ports extend low-frequency response to 50Hz while keeping the footprint at 32.30" wide, 4.10" deep and 2.20" high. HDMI eARC with 4K Dolby Vision passthrough carries lossless audio and 4K/120 or 8K/60 video through one cable.

Bundled WireLogic 48Gbps HDMI cable

An 8ft WireLogic Ruby Ultra High Speed HDMI cable rated for 48Gbps supports 10K, 8K/60 and 4K/120 signals with direction-controlled conductors for RF noise reduction. The box also includes a wall-mount bracket with template, power cords and a quick-start guide so the bar can be mounted or placed on a credenza without extra purchases. The JBL One App handles Wi-Fi setup, EQ presets and Easy Sound Calibration from a smartphone.

Questions about this item

How loud does the 260 W total power actually get in a living room?

The 260 W rating drives four 46 x 90 mm racetrack drivers and two 0.75" tweeters across a 50 Hz to 20 kHz range, delivering room-filling volume for movies and music without a separate subwoofer.

What does the HDMI eARC connection with 4K Dolby Vision passthrough allow me to do?

It carries lossless Dolby Atmos audio from the TV to the soundbar while passing 4K HDR10 and Dolby Vision video through to the display at up to 4K/120 Hz.

Will the 32.30" wide soundbar fit under my TV and can I wall-mount it?

The bar measures 32.30" W x 4.10" D x 2.20" H and includes a wall-mount bracket and template, so it fits under most TVs or mounts directly on the wall.
