Part of the Music City series, the <b>Klipsch Detroit Portable Bluetooth Speaker</b> is designed to honor the legacy of the Motor City, producing balanced and powerful audio that's as big as the 3-1-3. Audio that pumps out of dual 1" tweeters and dual 3" woofers, and enhanced by quad force-canceling passive radiators. If you need that sound to be even bigger, pair it with up to 10+ speakers in Broadcast Mode. Take that music anywhere with the included carry strap that can snake right through the body of the speaker. Stream your favorite playlists from a mobile phone or other Bluetooth device from up to 40' away for up to 24 hours on a full charge.
