Part of the Music City series, the Klipsch Detroit Portable Bluetooth Speaker 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.
