Polk Bar Liberated by Box

The Polk SurroundBar 500 ($999) was first announced a year and a half ago but took some fine tuning. It moves the messy details of connectivity to an outboard rack-size box, left, allowing the enclosure to be just 0.9 inches deep. It can operate in three-, five-, and seven-channel modes. The woofers at the sides have dual voice coils to make such complex motion possible. The picture may not do justice to the dimpled surface of the drivers, which we assume is for air-flow control. Oh, and have we mentioned that Polk has overhauled its excellent LSi Series for the first time since 2002? There are two towers, a monitor, two centers, and a surround. One or more of them will prove quite reviewable.
