Short answer: the JBL Partybox 100. It ranks #8 of 39 party speakers by sound quality, rated 4.4/5, at $499.99. The JBL Partybox 300 ranks #10, rated 4.3/5, at $300, $199.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the JBL Partybox 100: Quite neutral sound, pretty deep bass. Set against that: A slight peak in the upper mids.
What the JBL Partybox 300 gets right: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. The tradeoff: Hard to carry, too tall, drags on the ground.
Worth knowing: the JBL Partybox 100 is discontinued, though it still ranks #8 of 39 party speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the JBL Partybox 100. It is rated higher for sound quality, and the $199.99 you would save on the JBL Partybox 300 does not close the gap.
If battery life is a priority, the JBL Partybox 300 is rated for 18 hours versus 12 hours for the JBL Partybox 100.

JBL Partybox 100: $499.99 Discontinued Amazon eBay
Pros: Quite neutral sound, pretty deep bass. Measured bass extension of 41Hz (-10dB).
Cons: A slight peak in the upper mids. Slight TWS issue where the 2nd is slightly delayed. Just as loud and slightly deeper bass than a Stormbox Blast which is way smaller with better sound quality. Discontinued.

JBL Partybox 300: $300 Discontinued eBay
Pros: 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. Measured bass extension of 40Hz (-10dB).
Cons: 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. Discontinued.
