LG S80TR vs LG S90TR

The LG S90TR is a more premium alternative to the LG S80TR within LG's lineup. The main difference is the S90TR has the addition of two side-firing drivers in the soundbar, which widens the soundstage. The S90TR also offers a deeper bass, giving kick drums a little more thump, and its surround speakers are a little more balanced. However, both systems only offer Atmos drivers in the bar itself, so you don't get improved Atmos performance by paying more.
