Make sure to check the compatibility of the Bluetooth transmitter with your TV model before purchasing. **

Some soundbars also support the addition of a subwoofer for enhanced bass, further enhancing the overall audio experience. **

It is best to have at least two people to help carry and maneuver a TV of this size to ensure it is done safely and securely. **
