A:Answer I cannot say for sure, but I do know that voices come out of them. In our Roku TV it has an option to enhance voices, and we have that option chosen.
So whether it is the TV Option or the remote speakers, or the sound bar, or the combination, I cannot be certain, but I do know with the option selected vs. the option not being chosen it does make a difference.
Being a 62 Yr Old guy that's been around Helicopters most of my life, the Option helps me. Do I get it all, NO, but I do believe that it is NOT the TV, Sound Bar, Sub-Woofer, or remote speakers fault. Yes, that would be true.
