The LG XBOOM RNC7 packs double Super Bass Boost thanks to its 8? woofer and 5-speaker 3-way system, delivering room-shaking lows. It features dynamic multi-color LED lighting and party strobe effects synced to the beat or your phone’s flashlight. With Karaoke Star, you can control mic/music volume, use voice cancellation, and change key, while guitar and mic inputs let you jam freely. The speaker also supports Wireless Party Link (link two units), DJ effects via the XBOOM app, and records your mixes straight to USB.
