JBL Partybox Ultimate 2: £1,399.00 Peter Tyson eBay
Older model: the JBL Partybox Ultimate (rated 4.7/5).
Pros: A 1500W RMS system (up from the original Ultimate’s 1100W) driving dual 264mm subwoofers, dual 124mm mid-range drivers and dual 30mm horn-loaded PEN tweeters, with manufacturer-rated extension to 28Hz (-6dB) from a 1.05m-tall cabinet. Wi-Fi streaming with AirPlay 2, Chromecast and Spotify Connect sits alongside Bluetooth 5.3 and Auracast multi-speaker linking. Inputs cover an XLR line-in, mic, guitar, aux, optical and USB-C playback, and karaoke gets AI vocal removal. JBL One app control, a full-panel light show with floor projection, and wheels plus a handle for its 47.68kg. IPX4 splash resistance.
Cons: AC-only: there is no battery, so it needs mains power wherever it goes. At 47.68kg and just over a metre tall it is still a two-person lift despite the wheels, and 47.68kg is heavier than the 39kg model it replaces. IPX4 only shrugs off splashes, not rain or dust. No independent measurements have been published yet, so its real output and sound quality can’t be compared with ranked speakers. Not yet sold in the US.
