Short answer: the JBL Partybox Ultimate for bass. It has the absolute deepest bass of any Bluetooth speaker and moves on a convenient handle and wheels, but it is very large and heavy with no battery. The 330 is easy to move as well, though its sound is nearly identical to the 310 and Stage 320 despite the power bump, so it is probably not worth an upgrade if you already own one.
Buy the JBL Partybox 330 at $629.95 for a party speaker, or the JBL Partybox Ultimate at $1,499.95 for a large party speaker instead.

The Two Speakers In Full
JBL Partybox 330: $629.95 Amazon B&H Photo Video eBay
Older models: the JBL Partybox Stage 320 (ranked lower, rated 4.6/5), the JBL Partybox 310 (ranked lower, rated 4.5/5) and the JBL Partybox 300 (ranked lower, rated 4.3/5).
Pros: A highly complete rolling party speaker: removable battery, telescoping handle and wheels, light show, Auracast, USB-C lossless and optical inputs, plus dual mic/guitar inputs. It supplies a little more power than the JBL Partybox 310 and JBL Partybox Stage 320, while reviewers report better midrange clarity than the older JBL Partybox 310 and the same deep party-speaker bass.
Cons: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational. JBL removed the dedicated mic gain/control knobs found on earlier models, a real drawback for frequent karaoke use. Do not upgrade from a JBL Partybox 310 or JBL Partybox Stage 320 just for the higher watt figure.

JBL Partybox Ultimate: $1,499.95 Amazon B&H Photo Video eBay
Newer model: the JBL Partybox Ultimate 2, ranked lower, estimated 4.7/5.
Smaller models: the JBL Partybox Stage 320 (rated 4.6/5) and the JBL Partybox Club 120 (rated 4.5/5).
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.
