Product story
The LG S90QY (listed in the catalog as LG S90QY Soundbar) is a flagship 5.1.3-channel, 570W high-resolution home theater soundbar co-engineered with Meridian Audio, featuring triple up-firing overhead channels (including a dedicated center up-firing speaker), a wireless subwoofer, Dolby Atmos, DTS:X, and IMAX Enhanced certification.
Delivering 570W of total power across 9 speakers and a wireless subwoofer, the S90QY adds three top-mounted up-firing channels—left height, right height, and a specialized center up-firing voice channel that lifts dialogue directly toward the TV screen while left/right height channels bounce overhead Dolby Atmos and DTS:X spatial effects off the ceiling.
Co-developed with British audio pioneer Meridian, the S90QY incorporates Meridian Horizon up-mixing (converting 2-channel stereo into multi-channel surround) and supports 24-bit / 96kHz High-Resolution Audio. Using the LG Soundbar app, AI Room Calibration Pro measures room acoustics and adjusts frequency response automatically.
Rear ports include 1 × HDMI In and 1 × HDMI Out (eARC/ARC) supporting 4K pass-through with Dolby Vision, HDR10, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM) for consoles, plus an Optical input and USB port. Built-in Wi-Fi and Bluetooth 5.0 support Apple AirPlay 2, Chromecast built-in, Spotify Connect, and voice control via Amazon Alexa and Google Assistant. It is also compatible with the optional LG SPQ8-S wireless rear speaker kit (sold separately).
Before ordering from any seller in the BiponiBD catalog, confirm included wireless subwoofer and HDMI eARC cable, power voltage rating, and seller warranty terms.
