I'm working on a scene in a film where two actors are watching a video tape on a small (15"), vintage 1970s TV. I need to do some EQ on the sound that is supposedly coming from that TV. The director wants it to be just a tad exaggerated so that we can easily hear the difference in quality between the actors watching the TV and the TV itself.
Roughly, what would be the accurate audio frequency range of such an old TV that had, say, only one, cheap mid-range speaker in it?
