Our take on the JBL Bar 300MK2 5.0-Channel Dolby Atmos Soundbar

The JBL Bar 300MK2 is a 5.0-channel soundbar with Dolby Atmos and a built-in subwoofer, so it adds height and low-end without a separate box on the floor. It connects over HDMI eARC or Bluetooth and comes with a remote. It suits people who want a one-piece upgrade for a TV in a small or medium room. Against rivals it trades the deep bass of a dedicated subwoofer for a simpler setup, and it lacks HDMI pass-through, so you plug sources into the TV, not the bar.

What reviewers say

Owners of JBL's all-in-one bars tend to like the clean setup and the Atmos height effect for the size. The common complaint is that built-in bass cannot match a separate subwoofer, and that connectivity is limited.

What people mention
  • BassMixedListeners find the built-in subwoofer adequate for TV but short of a dedicated subwoofer for movies.
  • SetupPraisedOwners report a quick eARC connection and simple pairing.
  • Atmos effectPraisedHeight effects come through in small rooms, though they are not as pronounced as with up-firing rear speakers.
  • ConnectivityCriticisedThe lack of HDMI pass-through and extra inputs limits how many devices can connect.
  • DialoguePraisedSpeech is described as clear at normal listening levels.

Questions and answers

Does the JBL Bar 300MK2 come with a separate subwoofer?
No. The subwoofer is built into the bar, so there is no separate box or cable. Bass is therefore less deep than bars that ship with a dedicated subwoofer.
Does it support Dolby Atmos?
Yes. It decodes Dolby Atmos and projects height effects from the bar itself. The effect is strongest in small rooms with a flat ceiling.
Can I connect a console or Blu-ray player to the bar?
There is no HDMI pass-through, so connect sources to the TV and send audio to the bar over HDMI eARC. Bluetooth is available for phones and tablets.
Does it have rear surround speakers?
No. It is a 5.0 bar with no separate rear speakers, so surround comes from processing rather than speakers behind you.
Can I stream music to it?
Yes, over Bluetooth. There is no Wi-Fi or multiroom support, so it will not join a networked multiroom system.
