I have searched all of the threads on this TV and could not find much info on the audio. All Sony specs say are 2 bottom full range speakers. Are they on the bottom bezel facing forward? Does this TV perform OK without external audio amp and speakers? I have always been happy with Sony built in audio for basic programming... and I just want to make sure this set is no exception before I spring for it. I would appreciate feedback from anyone who has seen/heard one. Thanks!
