AT A GLANCE
Dedicated surrounds for true 5.1-channel sound
Bluetooth connection to mobile sources
Effective DTS Volume mode
Less impressive performance with music
A surprisingly good-sounding, high-value choice for movie sound, though serious music lovers might need to look elsewhere
Home theater, as I’ve always defined it, is the union of big-screen TV and surround sound. At their best, they have the power to suspend disbelief and pull you into a cinematic narrative or musical experience. Sometimes soundbars make the cut, and sometimes they don’t. Any decent-sounding soundbar—whether it has 2.0, 2.1, or 5.1 channels—is likely to improve over the awful speakers built into most TVs. Making the evening news intelligible is no small contribution to household happiness. But few soundbars try to cross the barrier from convenience to full-bore 5.1-channel rapture. The Vizio S4251W-B4 is just such a product.
