LG Soundbar 400W Dolby USC9S Atmos 3,1.3CH 2024 4K SC9S

The SC9S and NS70TR both offer advanced home theater experiences with support for Dolby Atmos and DTS:X audio formats, but they differ in audio channel configuration and connectivity features. The NS70TR provides a more immersive 5.1-channel system with wireless rear speakers, whereas the SC9S uses a 3.1-channel setup without surround speakers. In terms of network connectivity, the SC9S includes both Wi-Fi and Ethernet connections, making it more versatile for streaming, while the NS70TR lacks these wired and wireless network options. Additionally, the SC9S offers automatic room calibration via a measurement microphone, a feature not available on the NS70TR. Although the NS70TR is the newer 2024 model with Bluetooth 5.1 and 4K/120Hz passthrough, the SC9S supports HDMI 2.1 with eARC and VRR for enhanced video compatibility.
