Sonos Ultimate Immersive Set with Arc Ultra vs LG Immersive Suite 5 Pro

The LG Immersive Suite 5 Pro and the Sonos Ultimate Immersive Set with Arc Ultra share more than just similar naming conventions. Both setups feature a bar, sub, and two discrete satellites for a 7.1.4 configuration. In practice, their performances are very similar: both have very balanced default frequency responses and high max volumes. However, there are trade-offs in other areas, as the LG has a better center channel and more comprehensive sound enhancement options, while the Sonos boasts a wider soundstage and low latency over an eARC connection. Given the highly modular nature of each of these setups, you'll still want to consider which ecosystem you'd prefer to buy into, especially if you want to expand with more satellites down the line. For those with wider seating arrangements, the LG's positionally adaptive features (Sound Follow and DAFC) could enhance the system's appeal, too.
