I've seldom met a Bluetooth speaker that interested me, but I paid attention when Audioengine announced the B2 Premium Bluetooth Speaker. This powered speaker can play music streamed from any Bluetooth-enabled source (iPhone, iPad, iPod touch, Android devices, or Bluetooth-equipped Macs and PCs). It also has a minijack input. They have a built-in 24-bit digital audio converter (DAC), and they're designed around the Audioengine 2+ Powered Desktop Speaker. The woofers are made of kevlar, while the tweeters are made of silk. Plus, the cabinet is handmade wood (in three finishes). I look forward to testing this one in a full review. designed for the high end of the market, the B2 Premium Bluetooth Speaker are $299 and available now. They're eligible for the company's 30-Day Audition.
