You could call it a revolution, or you could call it a trend, but something exciting is happening at the budget end of home theater. In the past you had to spend a lot of money to get great performance. But thanks to brands such as Elac, Pioneer and Vizio you don't have to spend thousands -- you barely have to spend hundreds.

At $150, the Vizio SB3621n-E8's sound belies its compact size and oh-so affordable price. We'd have high praise for this sound bar system even if it was double the price. It's easily the best sounding affordable sound bar we've heard to date.

There are no "features" to speak of, just a wireless subwoofer and Bluetooth, but at this price you don't really need any more than that. Alongside Google's Chromecast Audio, the Vizio SB3621n-E8 is now one of the best deals in home theater. You could even pair the two together, hook them up to a TCL Roku TV and you have a really cool wireless streaming AV system for about $500.
