LG S90QY

In LG’s naming convention, the Q indicates that the soundbar supports 4K pass-through and high-resolution audio, while the Y signifies that the unit includes WISA (Wireless Speaker and Audio) technology. WISA allows the soundbar to communicate with compatible LG TVs completely wirelessly, reducing cable clutter. It also indicates the inclusion of Wowcast built-in for wireless rear speaker support.

The LG S90QY is a 5.1.3 channel system, meaning it features three distinct up-firing speakers built into the bar. Two are dedicated to the left and right channels to bounce sound off the side walls, and the third is a dedicated center up-firing channel for dialogue. This configuration creates a highly immersive Dolby Atmos and DTS:X soundstage.

Yes, when paired with select 2022 LG OLED TVs (like the C2 or G2 series), the S90QY supports the Wow Orchestra feature. This allows the soundbar and the TV's built-in speakers to work simultaneously, creating a larger, more unified sound field. You can control both systems' audio seamlessly using the LG TV remote via HDMI eARC.

The LG S90QY comes packaged with a dedicated wireless subwoofer out of the box to handle deep bass frequencies. However, if you want full surround sound, you must purchase LG's compatible wireless rear speakers (like the SPK8-S kit) separately. The soundbar natively processes 5.1.3 audio, ready to send the rear channel signals to the add-on speakers.
