Designed for LG QNED TVs 49 Inches and Larger

This 3.1.1 channel sound bar system pairs a wireless active subwoofer with a centre up-firing speaker to deliver Dolby Atmos and DTS:X audio. It is built to nest beneath stand-mounted LG QNED televisions of 49 inches or bigger, using WOW Orchestra to combine the TV and sound bar speakers under one remote.

Crest Design Metal Grille and Connectivity

The sound bar measures 37.4 inches wide by 2.5 inches high by 4.5 inches deep and weighs 6.6 lb, while the subwoofer measures 7.9 by 14.8 by 11.2 inches and weighs 12.7 lb. A metal grille protects drivers from dust, and connections include HDMI eARC with 4K Dolby Vision HDR10 passthrough plus Bluetooth 5.1 for wireless streaming.

Check TV Size Mounting and Power Requirements

Verify your LG QNED television is 49 inches or larger so the sound bar fits correctly beneath the stand. Confirm an HDMI eARC port is available for lossless audio and passthrough, and ensure a 240 volt mains supply matches the unit's power input. Wireless surround speakers are optional and sold separately.

Questions about this item

What does the HDMI eARC connection support on this sound bar?

HDMI eARC carries lossless audio formats such as Dolby Atmos and DTS:X from the TV to the 3.1.1 channel system, and it also passes through 4K 120 Hz video with VRR and ALLM.

How much space do the sound bar and wireless subwoofer need for placement?

The sound bar measures 37.4" wide, 2.5" high and 4.5" deep, while the subwoofer is 7.9" wide, 14.8" high and 11.2" deep, so allow clearance for both units.

How do I pair the wireless active subwoofer during setup?

Plug the subwoofer into mains power, turn on the sound bar, then press the pairing button on the subwoofer until its LED blinks; the link establishes automatically within seconds.
