One speaker, a subwoofer, a source component . . . and you.
Virtual surround is nothing new: Some people don't have the space, the know-how, or perhaps the ideal room layout for a pair of surround speakers for true 5.1-channel audio. Wireless surrounds are an option for some. But even those need a place to live, and they still require power cables. All manner of technologies have addressed the virtual-surround challenge, but not until I tried the two-piece Binaura Sound Environment B102A (in our November 2005 issue) did I believe that such simplified gear could produce truly respectable audio. Cambridge SoundWorks of Newton, Massachusetts, is the first third-party manufacturer to license Binaura's patented technology for their own products. They have integrated it into a complete home theater system—three boxes instead of two—with the addition of a progressive-scan DVD player/receiver. Said receiver provides Dolby Digital 5.1, Dolby Pro Logic II, and DTS decoding, and this signal then goes to the subwoofer, where all of the amplification and Binaura processing take place.
