Short answer: the JBL Partybox 310 if you can still find one, the W-King T12 if you want something currently sold new. The Partybox 310 ranks #4 of 53 party speakers at $579.95, against the W-King T12 at #22 for $379.99, a gap of $199.96. The JBL Partybox 310 is discontinued; its replacement is the JBL Partybox 330. If you are buying new, get the JBL Partybox 330.
The Partybox 310’s sound is the standout here. Its notes describe it as having the absolute deepest bass of any battery-powered speaker and the most balanced sound in its class, with performance very close to the newer Partybox 320. Bumping the treble one step in its app EQ reportedly makes it even more neutral. The W-King T12, by comparison, is described as boxy sounding and lacking the clarity of higher ranked speakers, though its own notes call it not a bad speaker for the price.
The W-King T12 answers with more raw power and a lower price. It puts out 370W against the Partybox 310’s 240W, using dual 8 inch subwoofers against the JBL’s 6.5 inch woofers, and it comes with a companion app-free EQ for bass and treble plus MicroSD playback the JBL lacks. It also has no app to manage.
Water resistance and portability favor the Partybox 310. It carries an IPX4 splash rating while the W-King T12 has no water resistance rating at all, and its integrated handle and wheels make it easier to move despite weighing more.
Buy the JBL Partybox 310 for the deeper, more balanced sound and easier portability, if you can find one since it’s no longer sold new.
Buy the W-King T12 if you want more raw wattage, MicroSD playback, and a lower price on a currently available speaker, and can live with a boxier sound.
