Sonos Sub
We're big fans of Sonos' wireless speakers, but they're not exactly built to handle deep bass. The Sonos Sub ($600-$700) is. This self-powered subwoofer connects effortlessly to your existing Sonos system, adding a healthy dose of low-end aptitude thanks to two force-canceling speakers that are positioned face-to-face to eliminate cabinet buzz and rattle. Available next-month in a gorgeous glossy black finish, with a matte black model arriving in October for a $100 discount.
