Audioengine is shipping its Audioengine 5 speakers designed for portable audio players, such as Apple's iPod. The system is powered by internal amps, and offers integrated subwoofer ports for low-end bass without the need for an external subwoofer. iPod owners can charge the device while listening using the built-in power port, and Apple Universal Docks or iPods can plug directly into the Audioengine "Combo Port." The Combo Port charger is compatible with the fifth-generation iPod, the iPod nano, and all other products that charge via USB. The Audioengine 5 provides the ability to stream music from a laptop directly to the speakers through Apple's Airport Express technology, as well as an AC outlet alongside a second auxiliary mini-jack for alternative audio input. The Audioengine 5 is available for $350, and ship with a three-year warranty.
