The speaker is part of the JBL PartyBox series, which means it's designed for large parties and can cover a huge space. It looks the part: it’s a massive system weighing nearly 40 kg with dimensions of 1049x455x440 mm. For convenient transportation, it features wheels and a handle, and the IPX4 splash-proof rating indicates that it's perfect for loud poolside, seaside, and other waterside parties.

You need not worry about the volume and sound quality either. The total system power is 1100 W. Two speakers and a mid-range driver ensure louder sound. Dual tweeters and a pair of subwoofers provide ample bass, while Dolby Atmos adds a surround sound experience. Enhancing the atmosphere is the JBL PartyBox Ultimate lighting. It’s not just lighting, it's a real light show with various effects, light trails, strobes, and even projections that cast on any surface where the speaker stands.

All this syncs with the music. You can adjust the lighting and its effects using the controllers on the top panel or in the JBL One mobile app (which also includes equalizer settings). For wireless connectivity, it’s equipped with Wi-Fi 6 and Bluetooth 5.3. Additionally, there are two microphone inputs and a guitar input socket, so the audio system can help create a true concert and karaoke experience. If one such speaker is not enough for you, connect multiple PartyBoxes into a stereo pair for an even broader soundstage.
