My favorite audio product of 2008 isn't precisely an audio productit's a home theater in a box. I'm referring to Polk's lovely SurroundBar 360, which sells for $1200 and gives you a low-profile 48" "sound bar" and a base station, which includes an optical disc player, DSP processing, and an AM/FM tuner. The base station, of course, contains all the amplification the sound bar requires. Also included is a special umbilical to connect the two piecesand, in a savvy little detail that tells you a great deal about how much thought has gone into the SurroundBar 360, the connectors on that cable cannot be connected "wrong."
