If you plan to purchase a 4K TV this Black Friday or want to upgrade your existing sound system, Best Buy has discounted several Vizio soundbars ahead of next week. To start, you can get the SB46514-F6 for $700, down from $1000. This 5.1.4-channel system comes with a 10-inch subwoofer and four upward-facing speakers (for Dolby Atmos), as well as support for Google Assistant. You can also stream music to it through WiFi and Bluetooth. Our friends at Wirecutter say the SB46514-F6 is "the best soundbar you can find in the $1,000-or-less price range."
