Short answer: the Partybox 110, and the gap is real. It ranks #9 of 53 party speakers at $379.95; the T9 Pro ranks #38 at $171.49, $208.46 less.
The T9 Pro leads with a longer spec sheet. 250W peak power, dual 6.5-inch woofers, a removable battery you can swap mid-party, and 12 preset bass EQ curves for different genres. Our notes describe the resulting sound as warm and somewhat gritty, not as detailed as higher-ranked speakers in the class.
The Partybox 110 wins with a simpler, more neutral tuning. It’s described as very neutral out of the box, slightly better than the Partybox 100 it replaced, with one small adjustment recommended: bump the treble one step in the app for the most balanced result.
Buy the Partybox 110 for the better-measured, more neutral sound. Buy the T9 Pro if the swappable battery and bundled bass presets are worth trading detail for.
There is a real gap in water resistance: the JBL Partybox 110 at IPX4 (splashing) against the W-King T9 Pro, which has no water resistance.
