Sonos Boost now available to strengthen signal to wireless speakers

The Sonos Boost is now available for everybody looking to solidify the connectivity in their wireless home speaker system. Boost will act a lot like Bridge, in that it's a dedicated hub for your Sonos speakers that plugs right into your home Wi-Fi router. Boost or Bridge is something of a necessity if you're using Sonos as a surroundsound system for your TV.
