JBL PartyBox Ultimate — Black, Single

The JBL PartyBox Ultimate is a mains-powered party speaker finished in black, designed for music playback and compatible live sources rather than battery-only use. JBL rates its amplifier output at 1100 W RMS under IEC 60268. Wi-Fi and Bluetooth provide music connections, while dual microphone and guitar inputs support appropriate external sources. Dolby Atmos music playback is available over Wi-Fi with suitable content and a compatible high-definition music-service subscription; ordinary Bluetooth playback should not be described as providing the same Atmos experience. The JBL One app controls supported music, equalisation and lighting functions, while the integrated PartyPad offers interactive effects. Wheels and a handle help move the speaker, but it still requires a mains electrical connection during use. IPX4 indicates splash resistance rather than immersion protection. This listing is for one original PartyBox Ultimate, not an Ultimate 2 or a pair of speakers. A mains cord is supplied; microphones, instruments, music-service subscriptions and extra speakers are not included.
