Our take on the JBL Bar 300MK2 5.0-Channel All-in-One Soundbar

The JBL Bar 300MK2 is an all-in-one 5.0-channel soundbar with Dolby Atmos, MultiBeam 3.0 and built-in bass ports, so it adds height and width to TV sound without a separate subwoofer. It is rated at 225 W RMS (450 W max) with a 50 Hz to 20 kHz range, and it streams over Wi-Fi 6, Bluetooth 5.3, AirPlay, Google Cast, Spotify Connect, Tidal Connect and Roon. PureVoice 2.0 lifts dialogue and SmartDetails keeps quiet cues audible. It suits people who want a clean one-box setup in a small to mid-size room; against rivals that ship a subwoofer it gives up deep low-end, and owners rate it well overall.

What reviewers say

4.6 / 568 ratings

Owners rate it 4.6 out of 5 and praise the wide Atmos sound and clear dialogue from a single box. Some note the bass cannot match a soundbar with a separate subwoofer.

What people mention

SoundstagePraisedOwners say MultiBeam and Atmos make effects feel wide and enveloping for a one-box bar.
DialoguePraisedReviewers report speech stays intelligible across scenes and volume changes.
BassMixedThe ported cabinet gives punchy bass, but some owners want more depth than a bar alone can deliver.
SetupPraisedBuyers describe calibration and streaming setup as quick and straightforward.
ConnectivityCriticisedThe single HDMI input is called limiting for people with several sources.
