A:Answer Please pardon us, but we are unclear about your inquiry about whether the LG 2.0-Channel Compact Bluetooth Soundbar SKM1 - Black, Model # SKM1, "elimintaes sound from the back of the TV", and will need some clarification.
Soundbars in general do not eliminate sound from the back of a TV.
The Soundbar is Bluetooth®-enabled, so it can be paired with a Bluetooth®-enabled TV for a wireless connection, and it also has an Optical Digital Audio Input that can be connected to the Optical Digital Audio Output on a TV.
The purpose of connecting a Soundbar to a TV is so you can route the TV's audio through the Soundbar to enhance the audio experience by providing better sound quality and a more immersive sound stage. Soundbars replace the TV's built-in speakers, offering a more dynamic and clear audio experience...^Ivan.
