The JBL Partybox Stage 520 is a powerful black speaker designed to bring high-energy sound to any gathering. It delivers 400 W of total power through a system consisting of two 7.5-inch woofers and two 1-inch dome tweeters, covering a frequency range from 40 Hz to 20 kHz for a balanced audio experience. To keep the atmosphere lively, an integrated LED light show is built directly into the front grille, while the top control panel allows you to fine-tune the audio using dedicated Bass, Treble, and Echo knobs, along with a Bass Boost button for extra depth. Connectivity is versatile, featuring Bluetooth 5.4 with multipoint support for easy switching between devices and USB playback for FAT16 and FAT32 formats. Musicians and performers can plug in directly using the dedicated guitar and microphone inputs, or use the Aux-In and Line-In ports for other audio sources. Moving the unit is straightforward thanks to the integrated top handle and bottom wheels, making it easy to relocate the party. The speaker connects to power via a 2-meter AC cable, ensuring you have enough reach to find a nearby outlet.
