Short answer: the Zealot ZE21. It ranks #18 of 98 boombox speakers by sound quality (rated 4.0/5) at $247.41 and is still sold new; the Soundcore Rave Party 2 ranks #62 (rated 3.1/5) and is discontinued, so it is only an option used.
The Zealot ZE21 is the better-sounding, longer-running pick. The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. It is rated for 40 hours of battery against 16 for the Soundcore Rave Party 2. It is rated IPX6 against IPX4 for the Soundcore Rave Party 2. The catch: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy.
The Soundcore Rave Party 2 is the lighter pick. At 10.1 lbs (4.6 kg) it weighs much less than the Zealot ZE21 at 20.4 lbs (9.27 kg). The tradeoff: Only IPX4 splash resistance, and bass extension seems limited.
Buy the Zealot ZE21. It is rated higher for sound quality; the Soundcore Rave Party 2 is no longer sold new.

Zealot ZE21: $247.41 Amazon $247.41 AliExpress $187.15 eBay
Pros: The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. Its TWS button can form a stereo pair with another compatible Zealot, and its large, rugged chassis gives it credible party-speaker scale. Measured bass extension of 36Hz (-10dB).
Cons: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy. The supplied sound modes do not fully correct the tuning; the most positive independent report required source-side parametric EQ. Treble is also soft and clarity trails better-tuned rivals.
