A bundled wall-mount bracket with template simplifies fixed installation. The JBL One App walks you through Easy Sound Calibration using the microphone, and PureVoice 2.0 sharpens dialogue at the touch of a button.

Questions about this item
How loud can the 260 W soundbar go before it distorts?
The 5.0 all-in-one unit delivers 260 W total power through four 46×90 mm racetrack drivers and two 0.75" tweeters with a 50 Hz–20 kHz response.
Does the soundbar run hot or make fan noise during a full day of playback?
The spec sheet lists no fan or thermal limits; the sealed enclosure relies on passive cooling and the 100–240 V AC supply.
Which TV connection is required to get Dolby Atmos and 4K Dolby Vision passthrough?
Use the single HDMI eARC port on the soundbar; the bundle includes a 2.5 m Austere V-Series 4K HDR HDMI cable for that link.
