Samsungs\u2019s 2013 AV products featured at this year's CES bring, as expected, a number of wireless connectivity enhancements. Samsung's Vacuum Tub Soundbar, the HW-F750 ($TBA), is intended to be placed beneath your TV and connects to your TV via Bluetooth. It also\u00a0integrates a vacuum tube amplifier into a soundbar for the first time. With the\u00a0AirtrackON function, users don't waste power by automatically turning on the soundbar when the TV is turned on. The HW-F750 comes with a separate, wireless subwoofer.
