This is the wireless speaker that finds and plays music that you verbally request from anywhere on your home network. A free Apple or Android app uses award-winning voice recognition software that lets you search for songs by speaking into your smartphone. The app scours your smartphone, a music library on a computer, or Internet radio stations and organizes results by artist, album, or song for easy navigation to the desired track. Simply touching the smartphone screen automatically streams the song to the speaker. The speaker has one subwoofer, two woofers, two tweeters, and five class-D amps that provide full-range sound. The speaker connects to your wireless home network and streams music from a smartphone, tablet, or computer, allowing you to play music from anywhere in your house. It can also stream YouTube video to a television via its built-in HDMI port (cable not included). Plugs into AC. 17" L x 8 1/2" H x 5 3/4" D. (9 lbs.)
