Used to work in advertising and clients always wanted to hear the spot on a crap soundbar to assess what it would sound like on the average home system. It took a few sessions with complaints about bad lip-sync to figure out that the soundbar had an inherent 2frame delay. I'm not sure how this is achieved, but I've found it in other soundbar monitors in other studios since, so I think it's common in the soundbars themselves.
