VIZIO SB4551-D5 5.1-Channel Soundbar System Reviewed

This is a true 5.1-channel soundbar system, as it comes with two dedicated surround speakers that measure a little less than 2.5 inches wide by 2.5 deep by 5.5 high. The surrounds are powered by the ampinside the sub, which means you have to connect them to the sub using the supplied speaker cables. Thankfully, VIZIO provides very long cables, which gives you some placement flexibility for both the surrounds and subwoofer. The SB4551 comes with an IR remote that arranges its 11 buttons (power, source, menu, volume, mute, etc.) into an intuitive fashion and includes a single-line LCD through which you can adjust various functions.
