#2 JBL Partybox Ultimate 2: $1,799.95 JBL $1,799.95 eBay

Older model: the JBL Partybox Ultimate (ranked lower, rated 4.7/5). See every JBL PartyBox generation.

Pros: A huge mains-powered party speaker with very loud output, deep bass, Wi-Fi streaming and inputs for mics and guitar. It plays louder on music than the JBL Partybox Ultimate and keeps usable bass down to 20 to 25Hz: in AudioTribe’s side by side test indoors it reached 111.3dBA and 114.5dBC against the original’s 107.7dBA and 112.9dBC, held about 116dB at 80Hz, and sounded a little more balanced. Outdoors at 7m it also beat the Sony ULT Tower Max in A-weighted loudness (101.0dBA against 98.8dBA). HammoTech found vocals clearer than on other JBL party speakers, helped by the dual 124mm mid-range drivers that join dual 264mm woofers and dual 30mm horn-loaded PEN tweeters in a 1500W RMS system. AirPlay 2, Chromecast and Spotify Connect sit alongside Bluetooth 6.0 and Auracast multi-speaker linking. Inputs cover an XLR line-in, mic, guitar, aux, optical and USB-C playback, and a touchscreen on top handles EQ, the light show, mic effects, DJ pads and AI vocal removal without the app. Wheels and a handle help move its 47.68kg. IPX4 splash resistance.

Cons: Its deep bass doesn’t hit as hard as the price suggests. With one of its two woofers now facing backward, AudioTribe measured it about 6.5dB weaker than the JBL Partybox Ultimate at 40Hz from the front with a flat EQ (about 88dB against 95dB), only matching it at 50Hz, and neither gets louder in the bass past roughly 55 to 65 percent volume. Outdoors at 7m the Sony ULT Tower Max was 5.5dB stronger on music in dBC (111.9dBC against 106.4dBC) and 5 to 6dB stronger on 40Hz and 50Hz tones, and both AudioTribe and HammoTech preferred the Sony’s sound. AC only, with no battery. At 47.68kg and just over a metre tall it is a two-person lift for stairs or a car, and heavier than the 39kg model it replaces. IPX4 only handles splashes. No microphone comes in the box.
