Eight years ago, Bowers & Wilkins released its first Zeppelin speaker dock. After a few updates along the way, the company nixed the dock and went wireless for the new model. The appropriately named Zeppelin Wireless keeps the airship-esque design while adding support for AirPlay, Spotify Connect and Bluetooth aptX connections. While the look might be familiar, the company says it redesigned "every element" to re-imagine "what is possible from a single speaker system." To do just that, Bowers & Wilkins used a group of five speakers: two Double Dome tweeters from its high-fi CM Series speakers, two mid-range drivers and a 6.5-inch subwoofer to manage the low end. The cabinet itself was also retooled for added strength and to reduce vibrations for improved overall sound quality.
