All three soundbars were developed in conjunction with Meridian Sound, an English manufacturer known for its high-fidelity audio and video components. LG calls out three features: Bass and Space, Image Elevation, and Upmix.
Bass and Space supposedly improves the soundstage with added bass. Image Elevation creates an imaginary 3D space that emits sound to “lift” the soundstage. Finally, Upmix takes two-channel audio and makes it sound like multi-channel audio without noise or distortion.
LG specifically calls out the SL9YG, which features a built-in gyroscope that determines how you orient the soundbar. The SL9YG then adjusts the sound output accordingly.
The SL10YG, SL9YG, and SL8YG also support Dolby Atmos and DTS:X for surround sound. LG will offer a wireless rear speaker kit that should increase the bass output.
Lastly, all three soundbars feature built-in Google Assistant functionality. That means the soundbars listen to voice commands and act as smart home hubs that can control other connected devices.
LG didn’t say how much the soundbars cost or when they’ll launch. That said, LG will show them off during CES and might have more information to share then.
