I know that the Sonos Playbar is somewhat dated technology. Would it be acceptable for normal TV viewing and streaming movie watching?
It's a speaker. I'm not sure those ever really become dated. My problem is it turns itself off after a period of inactivity. I have a Bose SoundTouch 300 in the bedroom and the Sonos Playbar in the living room and the auto turn-off is pretty annoying. The Bose doesn't have that problem.
