Popular Science featured the Yamaha YAS-207 sound bar in its piece on all the gear you need build a backyard home theater. The sound bar has DTS Virtual:X built in, which recreates surround-sound without needing to place speakers all around you. It reproduces a virtual height and depth that wouldn't normally be possible with a single, forward facing speaker. Today, it's 10 percent off the normal price and available for $270.
