Short answer: the JBL Partybox 300. It ranks #8 of 50 party speakers by sound quality at $300; the W-King T12 ranks #21 and costs $399, so there is little reason to consider the other one.
What the JBL Partybox 300 offers: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. 2x 6.5” woofers + 3x 2.25” tweeters, bass boost function, 45Hz-20kHz frequency range. 18-hour battery with 10400mAh capacity. Multiple inputs (RCA, USB, 3.5mm aux, mic, guitar). LED light modes (meter/pulse/party). True Wireless Stereo pairing up to 2 units. Watch for: Hard to carry, too tall, drags on the ground. Max spl and bass extension are only as good as the Partybox 100. No real reason to ever get one, get a Partybox 100 instead.
What the W-King T12 offers: Relatively cheap for what you get. Not a bad speaker for the price Watch for: Boxy sounding and doesn’t have the clarity of the higher ranked speakers
Buy the JBL Partybox 300. It ranks higher for sound quality than the W-King T12 and costs less, which settles it without a real tradeoff to make.
