The Acoustic Research ARIR600i is a WiFi shelf-system and table-top radio designed to aid online radio listeners by allowing them to disconnect traditional Internet cables so that they can utilize their radio with more flexibility and portability. The second of two Acoustic Research ARIR shelf systems, the Acoustic Research ARIR600i is an upgrade from the Acoustic Research ARIR200 in that it adds along a subwoofer and an iPod dock for charging one's iPod or playing back music. Other than those two differences, the ARIR600i is essentially a duplicate of its downgraded. For instance, the ARIR600i also functions as both a high-performing Internet radio and an alarm clock radio, thereby allowing users to choose whether they desire to wake up with a traditional sleep/snooze, or with some form of Internet content. In fact, the ARIR600i’s built-in WiFi connectivity allows it to connect easily to any wireless home router or WiFi network within range. The ARIR600i also features a traditional AM/FM radio, a USB port, an Ethernet port, and 512MB of internal memory for 10 hours of recorded music. Lastly, the ARIR600i offers free access to Slacker Personal Radio, a Personal Portal Account, and a pre-paid 4 year subscription to on demand weather from Weatherbug. The Acoustic Research ARIR600i retails for a more expensive $199.99 (versus $129.99) and comes with a 1 year limited warranty.
