Short answer: the Partybox 520, if the budget stretches that far. It ranks #7 of 12 large party speakers at $799.95; the T12 ranks #18 at $379.04, $420.91 less.
The T12’s own review is modest: relatively cheap for what you get, not a bad speaker for the price. Its cons describe a boxy sound lacking the clarity of the higher-ranked speakers in the class.
The Partybox 520 is JBL’s biggest battery-powered speaker currently made, with the same handle, wheels, and lightshow the rest of the Partybox line offers.
Buy the Partybox 520 for the flagship experience if budget allows. Buy the T12 for a genuinely large party speaker at less than half the price.
If battery life is a priority, the W-King T12 is rated for 25 hours versus 15 hours for the JBL Partybox 520.
There is a real gap in water resistance: the JBL Partybox 520 at IPX4 (splashing) against the W-King T12, which has no water resistance.

The Two Speakers In Full
JBL Partybox 520: $799.95 Amazon B&H Photo Video eBay
Pros: JBL’s biggest battery-powered PartyBox combines very high output, deep chesty bass, wheels and a telescoping handle with a capable app EQ, lights, USB-C audio and mic/instrument inputs. RTINGS finds it loud enough for backyards and unusually well-equipped for a battery party speaker.
Cons: It is very large and heavy, Bluetooth latency is high for video, and its front-facing design loses much of the mids and treble to people off to the sides. The bass-heavy default can also make dialogue less clear without EQ.

W-King T12: $379.04 Amazon Aliexpress eBay
Pros: A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. Its claimed 25-hour battery and trolley-style form make it practical where high output matters more than compact size.
Cons: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound. It is a 15kg, 75cm-tall speaker with no water rating and no app; the physical tone controls are its only meaningful way to adjust the sound.
