The VIZIO SB46514-F6 46-Inch 5.1.4 Dolby Atmos Sound Bar System features a 46-inch sound bar unit with two up-firing drivers, two rear satellite speakers with up-firing drivers, and a wireless 10-inch subwoofer -- offering a robust Dolby Atmos experience that feels more like a full-fledged home theater setup than a "sound bar" package. Unfortunately, though an update is in the works, a current limitation causes the rear heights to simply play the same content as the front heights, preventing genuine 5.1.4 playback. Likewise, the system does not offer DTS:X decoding. Still, even with some flaws, this is one of the most powerful and enveloping sound bar systems I've ever heard. The current lack of discrete front and rear heights is disappointing, but under the assumption that an update is coming, the overall package remains Recommended.
