Zvox's Z-Base design is so superior to the design of other sound bars, it's shocking that it hasn't been copied yet. Most sound bars have a tubelike shape and are designed to sit in front of your HDTV. That arrangement can work fine, but it can look awkward and sometimes the TV's IR receiver is blocked. The Z-Base design gets around all of these issues by acting as a stand for the TV. (The Z-Base 580 is designed to hold TVs 37 to 72 inches, up to 160 pounds.) The result is the Z-Base 580 looks more like a piece of furniture than an obtrusive home audio system.
