The JBL Bar 800MK2 is a high‑power home sound system that brings nearly theatrical surround sound into your living room. With 780 watts of maximum output across a 7.1‑channel setup, this system offers a rich, room-filling experience. It features Dolby Atmos support, meaning you can enjoy three-dimensional audio effects that simulate height, directionality, and depth. What makes it especially compelling is its wireless detachable surround speakers, which allow for flexible placement, plus a dedicated 10″ subwoofer for powerful bass. This combination delivers not just loudness, but a layered and immersive sonic environment that works for movies, music, and games alike.

Design and Build Quality: Premium Construction Meets Practical Flexibility

Sleek Soundbar with Detachable Surround Speakers

The JBL Bar 800MK2 main soundbar is well‑built and elegantly designed. It uses six racetrack‑shaped drivers (44 × 80 mm) and two 1″ tweeters, which together produce a broad and detailed sound. Removing the two wireless surround speakers from either end of the bar is surprisingly easy — you can do it with one hand. This design choice provides genuine surround sound when you place the speakers behind your seating position. When you’re done, you simply return them to the bar to charge.

Solid Wireless Subwoofer

The JBL Bar 800MK2 system includes a 10-inch (260 mm) wireless subwoofer, which is large enough to deliver deep and punchy bass. Despite this size, the subwoofer is wireless, so you don’t need extra cables stretching across the room. The build feels sturdy, and its design ensures that low frequencies are well supported, making explosions or musical basslines feel full and powerful.

Good Portability and Ergonomics

Each of the detachable surround speakers weighs only about 0.7 kg, making them easy to pick up and move. The soundbar itself weighs around 5 kg, while the subwoofer is about 8.1 kg. The detachable speakers can run on battery for up to 10 hours, giving you flexibility to use them even when you’re away from your TV.

Audio Performance: Immersive Surround and Detailed Sound

True 7.1‑Channel Output

With its 7.1‑channel configuration, the JBL Bar 800MK2 offers a true surround experience. While many soundbars fake surround sound by using reflections or virtual techniques, this one gives you dedicated rear speakers — something that significantly improves spatial realism.

Dolby Atmos Support

The  JBL Bar 800MK2 system supports Dolby Atmos, which enables more immersive, three-dimensional audio. You will hear sounds moving not just around you but also “above” or “overhead,” depending on how the mix was done. This gives your media more depth and realism, enhancing movie scenes like flying aircraft or ambient background effects.

MultiBeam 3.0 for Wide Sound Field

JBL’s MultiBeam 3.0 technology ensures that sound is distributed broadly across your room. This helps prevent “sweet spot” issues — you don’t need to sit in precisely one place to appreciate good surround; the soundstage is designed to reach you even if you’re off-centre.

PureVoice 2.0 for Clear Dialogue

Dialogue clarity is a strong point. The JBL Bar 800MK2 PureVoice 2.0 system dynamically enhances speech. Whether someone whispers or speaks softly, the soundbar boosts those quieter lines so you can catch every detail, even during action scenes or musical performances.

SmartDetails for Subtle Audio Nuances

Thanks to SmartDetails, quiet ambient sounds — like footsteps in the distance, rustling leaves, or gentle room tone — come through without being masked by louder effects. This adds realism and helps you pick up finer details that elevate the cinematic effect.

Punchy Bass from the Wireless Subwoofer

The 10-inch subwoofer has enough power (300 W max at THD 1 %) to deliver financial, gut-punch bass. Its output supports the lower end of the frequency range (down to 35 Hz), giving dynamic depth to explosions, musical drops, or bass-heavy tunes. The wireless nature means placement is flexible, so you can find a spot that blends well with your room acoustics.

Connectivity and Inputs: Modern Flexibility

HDMI eARC with 4K and HDR Passthrough

The JBL Bar 800MK2 soundbar includes an HDMI eARC port, which supports uncompressed audio formats so you can make full use of Dolby Atmos. It also supports 4K video pass-through, including Dolby Vision and HDR10+, meaning your high-resolution sources (like Blu-ray players or game consoles) connect simply and deliver both excellent video and audio.

Bluetooth, Wi-Fi, and USB

You get Bluetooth v5.3, making it easy to stream audio from your phone or tablet. For more stable and high-quality streaming, the system supports Wi-Fi (both 2.4 GHz and 5 GHz) so you can play directly from services like Spotify, Tidal, or podcasts. There’s also a USB‑A port, although in some regions, it is meant for service only (playback might be limited depending on the version).

Optical Input

If you want to connect older devices or prefer a simpler setup, there is an optical (TOSLINK) input. That gives you room to connect legacy gaming consoles, media players, or even older TVs without relying on HDMI.

Smart Features and App Integration

JBL ONE App Integration

You can control and fine‑tune the soundbar using the JBL ONE app. Through the app, you can run an automatic calibration process that analyses your room. Then, JBL Bar 800MK2  adapts the 3D surround effects to suit your space. The app also provides an equaliser, letting you tailor bass, treble, and other parameters to your taste.

Night Listening Mode

A very handy feature is Night Listening: you press a button in the app, and the soundbar and subwoofer mute, while the detachable surround speakers continue to play. This mode is ideal when you want to listen quietly — for example, when someone else is sleeping. It delivers a focused, intimate soundstage without disturbing others in the room.

Voice-Assistant Compatibility

The system works with smart voice assistants. You can link the soundbar to speakers with built-in Google Assistant or Siri, enabling voice control for playback, volume, and more. This makes it easier to integrate into a smart home setup.

Summary: Overall Assessment of the JBL Bar 800MK2

The JBL Bar 800MK2 is a standout soundbar system that balances power, flexibility, and smart design. With 780 watts of output, true 7.1 surround, Dolby Atmos support, and high-quality bass, it’s well-suited for home cinema and gaming. The detachable surround speakers give it a real edge over more basic soundbars, and the wireless subwoofer helps you enjoy deep, room-shaking bass without cable clutter.

While not without trade‑offs — including no dedicated upward-firing drivers and the need to recharge surround speakers — this system is very compelling for those wanting immersive home audio without a tangle of wires. It brings cinema-level sound into the home, backed by JBL’s trusted engineering.
