If you want to add a little style and class to your bluetooth audio experience, then you need to check out the Audioengine B2 Bluetooth Speaker ($300). The first thing you’ll notice about the B2 is the beautiful hand-built wood cabinet. It not only looks great, but is also acoustically isolated to provide the best sound possible. The extended range custom 2.75″ woofers made from Kevlar and the 3/4″ tweeters provide a silky smooth sound. The frequency response is respectable coming in at 65Hz-22kHz. This is a portable speaker so don’t expect ground thumping bass.
