A:AnswerThere are speaker grill openings on each side of the bottom of the TV frame just inside the legs. The actual speakers mainly produce treble frequencies.
To make a slightly fuller sound, I set the TV's graphic equalizer (EXPERT SETTINGS in SOUND) as follows: 100 Hz = +5; 200 Hz = +5; 500 Hz = +5; 1 kHz = -5; 2 kHz = -10; 5 kHz = -10; 10 kHz = -10. You may prefer different settings.
For actual good sound, you will need a sound-bar or home theater system.
