I think that the speakers on all the large flat screens are on the backside of the TV and they all sound muffled without a sound bar or a home theater type sound system.
At least that's my experience with them.
This is correct. Speakers are not pointed in the right direction. I have 3 sound bars. One in my living room, garage, and race car trailer. It's nice for streaming music, where ever I am at from my phone.
