Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox Stage 320 ranks #3 of 39 party speakers by sound quality at $499.95; the JBL Partybox Ultimate ranks #2 of 12 large party speakers by sound quality at $1399.95.
Short answer: the JBL Partybox Ultimate edges it out, 4.7 against the JBL Partybox Stage 320’s 4.6. One thing about the JBL Partybox Stage 320: Handle and wheels are convenient. The JBL Partybox Ultimate’s headline feature is a true large-venue party speaker: its 1,100W system, dual 9-inch woofers and six-driver array produce exceptionally deep, authoritative bass and very high clean output.
Where they differ on paper:
- Battery Life: 18 hours (Manufacturer specified) vs No Battery
- Drivers: 2x 6.5” woofers, 2x 25mm tweeters vs 2x 9” subwoofer, 2x 4.5” midrange, 2x 2.75” tweeter
- Amplifier Power: 240W vs 1100W
- EQ: Yes (5 band) vs Yes (3 band)
Consider the JBL Partybox Stage 320: Handle and wheels are convenient. Watch for: slightly sibilant in the treble at full blast. Price also favors it, $499.95 versus $1399.95.
Go with the JBL Partybox Ultimate for a true large-venue party speaker: Watch for: at 39kg and more than a metre tall, this is not casually portable despite the wheels. It’s the pricier of the two, $1399.95 versus $499.95.
Buy the JBL Partybox Stage 320 ($499.95) for a party speaker; the JBL Partybox Ultimate ($1399.95) suits a large party speaker instead.

JBL Partybox Ultimate: $1,399.95 Amazon B&H Photo Video eBay
Pros: A true large-venue party speaker: its 1,100W system, dual 9-inch woofers and six-driver array produce exceptionally deep, authoritative bass and very high clean output. Independent reviews praise its unusually clear, articulate sound at extreme levels. Wi-Fi streaming, app EQ, inputs for two mics/guitar, USB playback, Auracast, a polished light show and wheels make it unusually complete for karaoke and DJ-style use.
Cons: At 39kg and more than a metre tall, this is not casually portable despite the wheels. It needs AC power, has no battery and only IPX4 splash resistance. Reviews also note that its bass-heavy presentation can obscure fine detail and overwhelm a small room; its size and cost only make sense for very large spaces or frequent events.
