Hi Philly.
Your inquiry is appreciated.
The speakers on the LG - 60" Class (59-1/2" Diag.) - LED - 1080p - Smart - HDTV - Model # 60LB6300 are located at the bottom of the chassis just inside where the legs attach to the TV. The speakers are what are commonly referred to as bottom firing speakers which are angled in such a way that the sound is meant to reflect off whatever platform you set the TV on up toward the listener...IFV
