Vizio adds two rear-channel speakers along with a wireless subwoofer to the sound bar mix, giving you an entire 5.1-channel sound system. The rear satellites link to the subwoofer, which in turn itself communicates together with the sound bar with 2.4GHz radio signals that offer a maximum range of 60 feet.
Experts say typically the lack of wires keeps the installation process simple. The device offers only one optical digital audio input the other analog stereo input, which helps with ease but limits versatility. If you want a more basic setup, reviewers say the Sony HT-CT150) offers good quality of sound at a budget price. As the wired subwoofer does clutter up things a bit, and surround effects are less impressive by a good margin, the improved connectivity -- notably three HDMI 1.4a inputs -- is a notable plus.
