My hearing isn't at it's best as I get older but I've come across (several times) sound differences when movies are being streamed (Netflix, Prime etc) where people speaking is lower sound whereas other sound like music in movie ok. I seem to need to raise TV volume when there's speaking which becomes too loud for the movie music etc. Is it that the sound for speaking put through like a central speaker that sound bars have?. This new TV is great but maybe I could connect a middle speaker somehow without sound bar?
