Excerpt: No home theater system is complete without both a big screen and surround sound. But it’s no secret that the former is more popular than the latter. Surround’s Achilles’ heel is the audio/video receiver, with its peculiarly named features and labyrinthine menus. On the other hand, speakers are fairly straightforward. They usually have no controls aside from a few on the sub. Cable connection is red to red, black to black.
