These sit in different size classes, so this is not a straight ranking comparison. The JBL Partybox Ultimate ranks #2 of 12 large party speakers by sound quality at $1,499.95; the Soundboks Mix ranks #25 of 40 party speakers by sound quality at $799.
The case for the JBL Partybox Ultimate: 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. The tradeoff: At 39kg and more than a metre tall, this is not casually portable despite the wheels.
What the Soundboks Mix does well: USB-C fast charging (65W) for the swappable battery, up to 40 hours of battery life at mid-volume, IP65 dust/water resistance, and TeamUp linking with up to 5 other SKAA-equipped Soundboks speakers. The catch: Doesn’t have as deep of bass as higher-ranked speakers, and can sound somewhat bright in the treble.
Buy the JBL Partybox Ultimate ($1,499.95) for a large party speaker; the Soundboks Mix ($799) suits a party speaker instead.

The Two Speakers In Full
JBL Partybox Ultimate: $1,499.95 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. JBL’s wired daisy chain only works with other JBL speakers.

Soundboks Mix: $799 Soundboks Amazon eBay
Older model: the Soundboks Go (rated 3.1/5).
Pros: USB-C fast charging (65W) for the swappable battery, up to 40 hours of battery life at mid-volume, IP65 dust/water resistance, and TeamUp linking with up to 5 other SKAA-equipped Soundboks speakers. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage.
Cons: Doesn’t have as deep of bass as higher-ranked speakers, and can sound somewhat bright in the treble. Only 72W of output and a single 10-inch woofer, less powerful than the Soundboks Go or Soundboks 4, and no microphone input for karaoke like the Pro Panel models.
