Don’t know about this one, haven’t looked beyond the headline, but not all TV sound systems are built into the screen. Some do come with legitimate external speakers.

Many Atmos soundbars sound much better than they ought to; with what seems like real surround considering they’re, well, just a soundbar with no actual surround speakers. High end audio can be extremely complicated now, it’s not as simple as just having a speaker in a spot aimed at the couch.
