JBL PartyBox Ultimate 1100W Wireless Party Speaker

The JBL JBLPARTYBOXULTAM is a party speaker that pushes 1100 watts of power, giving your living room, backyard, or rental hall the feel of a full-scale venue without losing clarity at high volume.

Its acoustic design pairs dual 9-inch woofers with dedicated midrange drivers and tweeters, creating bass you can feel while keeping vocals and details sharp. When you stream content that supports Dolby Atmos, the speaker delivers a spacious listening experience that wraps sound around your guests.

Music sources are almost unlimited. You can stream through Wi-Fi 6 or Bluetooth 5.3, send tracks from AirPlay or Chromecast, or integrate the speaker with Alexa and Google Home for voice control. Performers can plug in two microphones for instant karaoke or connect a guitar for live sets. Wherever you place the speaker, built-in self-tuning technology analyzes the surroundings and adjusts the sound automatically.

The built-in light show adds another layer of energy. LEDs pulse with the beat, strobe effects flash on crescendos, and floor-level lighting sets the room’s mood without extra fixtures. An IPX4 rating handles splashes during poolside gatherings, and when it is time to move, wheels and a sturdy handle let one person roll the speaker to the next spot.

The JBL One app offers quick control over lighting patterns, EQ settings, and speaker pairing. A USB port lets you play music directly from a drive or charge a phone so the playlist never stops. From weekend tailgates to holiday parties, this speaker brings professional-grade sound and lighting in a form that is easy to set up and enjoy.
