Not thrilled with the Zune's Wi-Fi music-sharing feature? Kicker's ZK500 Zune speaker dock gets your music social the old fashioned way: by pummeling it at people's heads. The ZK500's two 5-inch drivers, silk-dome tweeters, and a monstrous 6-inch bass reflex port are powered by a total of 40 desk-shaking watts of power, packed into an enclosure that looks like it fell off the Death Star.
You can find our full review of the ZK500 over at CNET Reviews, but you won't find this video of me pushing the system to its limits in a quiet corner of our office.
(Note: The video's poor sound quality is the result of my camera's microphone being blown into oblivion, and does not reflect the actual sound of the ZK500.)
