The XtremeMac Tango Bar looks deceptively simple at first glance. It has a single USB cable that’s used to deliver power and sound from your computer. It’s not minimalist inside, though. This 10W speaker has a “six-speaker configuration with dual dome tweeters, midrange/bass drivers, and passive radiators gives you best-in-class audio.” It also has an aux-in jack so you can use it with your MP3 player or other mobile device. It even has a headphone jack and a sub-out jack so you can connect a subwoofer. Although it looks great sitting under your iMac or Cinema Display, it works with any Mac or PC. It’s available at various retailers. The Apple Store has it for $99.95.
