Whether branded Dolby, DTS, or something else, this is a 5.1 system, with the “point one” referring to a separate channel for a subwoofer. The traditional surround-sound specification calls for five full-range speakers: one center channel, left and right up front, plus left and right speakers mounted on either side of your listening area.

And keep in mind that the definition of very good here might include “better than you have ever heard before.” But if you are willing to settle for very good, then you now have another option: a wireless surround system. If you want the absolute best sound possible, there’s still no way around doing that work. For years, that meant doing some extensive (and, sometimes, expensive) wiring for at least five separate speakers plus a subwoofer. Every good home theater starts with two fundamentals: the largest and sharpest screen possible, and high-quality surround sound to accurately reproduce the multi-channel soundtracks of modern films and digital entertainment.
