Overview
The JBL Bar 300MK2 is a 5.0 channel soundbar rated at 450W total power, with HDMI, Bluetooth and Wi-Fi connectivity plus wall-mount hardware included. It targets buyers wanting a single-bar upgrade over TV speakers without adding a subwoofer box or satellite units.
JBL's own driver technology is credited under brand tech, and the black finish is built to sit under most TVs without standing out. No dedicated subwoofer is listed in this spec data, so the 5.0 channel layout relies on drivers built into the bar itself for bass.
- 5.0 channel array
- 450W rated power
- HDMI, Bluetooth and Wi-Fi
- 37 inch bar width
Who it's for
Fits a bedroom or living room where a single wall-mountable bar covers TV audio plus wireless streaming from a phone. Less suited to buyers who want deep, room-filling bass from a separate subwoofer unit.
Pros and cons
- HDMI, Bluetooth and Wi-Fi all included
- Wall-mount hardware included in the box
- Compact 2 inch height fits under most TVs
- No separate subwoofer listed in the spec
- Per-channel power breakdown not provided
Performance notes
The 5.0 channel layout spreads 450W of rated power across the bar's internal drivers rather than external satellites. HDMI covers TV audio return, while Bluetooth and Wi-Fi both handle wireless streaming from different source types.
