7.1 surround sound is the latest surround sound standard. Compared to 5.1 surround sound, it adds two side speakers bringing the total number of speakers to 8 (when counting the subwoofer as one speaker). More and more movies are available that come with a 7.1 sound track although 5.1 is still the most popular format. Even though most AV receivers support 7.1 surround sound, the majority of installations are still 5.1 setups. This may be in part because the majority of available movies comes with a 5.1 surround sound track and also because setting up two additional speakers adds another element of complexity. In this post I will look at some options that help in the installation, primarily in avoiding lots of speaker cable clutter.
Wireless speaker kits such as newest wireless models from Amphony cut some of the speaker cords. These sets are available for up to four wireless speakers. In a 7.1 setting, you most likely want to make the two rear and the two side speakers wireless since those speakers are the farthest away from the DVD player. If you want to make the subwoofer wireless then you can add an audio transmitter with a line-level audio receiver. Some subwoofers come with wireless extension kits.
