Definition: powered speaker

A loudspeaker with a built-in amplifier. Powered speakers are widely used because they only need an AC power source if they are wireless (Wi-Fi or Bluetooth). If battery powered, there is no wiring required. Powered speakers may also use cables wired to a receiver's pre-amp outputs, and some speakers can hook directly into the network via Ethernet. Many powered speakers today are controlled by apps in smartphones and tablets. See Sonos, AirPort, Android dock, Apple dock and Chromecast.
