Key Features
1. True Wireless Detachable Surround Speakers
Instead of traditional wired rear speakers, the JBL Bar 800 MK2 includes detachable wireless speakers that magnetically dock on the main unit when not in use. When placed behind you, they create authentic surround effects—perfect for movies, gaming, and immersive audio.
This flexibility means you can switch between:
-
Standard front-firing soundbar mode
-
Full 7.1 surround mode
-
Portable speaker mode for background music in another room
2. Dolby Atmos 3D Sound Technology
The soundbar includes upward-firing speakers that reflect sound off the ceiling to create the illusion of height. Dolby Atmos allows you to hear effects coming from above—like rain, helicopters, explosions, or ambient environmental sounds—making the experience more realistic and cinematic.
3. 780W Total System Power
With up to 780W of output power, the JBL Bar 800 MK2 delivers loud, dynamic, and room-filling audio. The large 10-inch subwoofer provides deep, punchy bass that enhances action scenes and music.
Whether you’re watching movies, listening to music, or gaming, the power output ensures clarity and impact.
4. MultiBeam™ 3.0 for Wider Soundstage
JBL’s MultiBeam technology creates a broader and more immersive sound field without needing multiple speakers. It makes voices clearer, sound effects more detailed, and music more dimensional.
5. PureVoice™ Dialogue Enhancement
Dialogue clarity is crucial, especially for movies or TV series where background music can overwhelm speech. PureVoice uses advanced algorithms to enhance human voices without affecting other sound elements.
6. Modern Connectivity
The JBL Bar 800 MK2 offers:
-
HDMI eARC with 4K Dolby Vision passthrough
-
Bluetooth and Wi-Fi
-
Apple AirPlay, Chromecast, and Spotify Connect
-
USB and Optical inputs
-
A companion app for sound calibration and updates
This wide compatibility makes it easy to integrate into any TV, gaming console, or streaming setup.
7. Night Mode & Flexible Listening
For late-night watching, you can:
-
Reduce bass
-
Lower dynamic range
-
Move detachable speakers to the front
-
Mute the main subwoofer
This makes it perfect for apartments or shared living environments.
