DESC: The Panasonic SC-HTB520 240W 2.1 Channel 3D Blu-ray Sound Bar features a subwoofer that radiates downward, delivering more dynamic bass to the listener. The 3D Pass Through seamlessly delivers 3D through your Blu-ray player. With the Clear-Mode Dialog the audio is lifted toward the TV screen and is accurately synchronized with your favorite movies or TV programs. Plus the design complements the look of any 42-40 inch TV. Connection and installation could not be easier, thanks to the system's compatibility with ARC (Audio Return Channel), which allows receiving audio signals from the TV. Simply place it by the television or wall mount for a custom installation (via supplied wall mounts) and connect it with just one HDMI cable.
