Short answer: the Zealot S89. It ranks #19 of 98 boombox speakers by sound quality, rated 4.0/5, at $246.99. The Soundcore Boom 2 Plus ranks #37, rated 3.6/5, at $179.99, $67 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Zealot S89 is the better-sounding, longer-running pick. A 16.1 lbs (7.3 kg) boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. It is rated for 40 hours of battery against 20 for the Soundcore Boom 2 Plus. The catch: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
The Soundcore Boom 2 Plus is the lighter choice. Quite a bit lighter than most of the other boombox size speakers. At 8.4 lbs (3.8 kg) it weighs much less than the Zealot S89 at 16.1 lbs (7.3 kg). It supports AAC Bluetooth, which the Zealot S89 lacks. The tradeoff: Warm tuning meaning a rolled off treble and some upper bass boost.
Buy the Zealot S89. It is rated higher for sound quality, and the $67 you would save on the Soundcore Boom 2 Plus does not close the gap.

Zealot S89: $246.99 Amazon $246.99 AliExpress $193.58 eBay
Pros: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. Listener comparisons find it capable of very high output and substantial bass for outdoor use. A great value for its bass, battery life and maximum volume. Measured bass extension of 36Hz (-10dB).
Cons: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers. The heavy cabinet and basic finish also make it less polished for daily portability, while its multiple EQ modes cannot substitute for a genuinely neutral tuning.

Older model: the Soundcore Motion Boom+ (ranked lower, rated 2.9/5). See every Soundcore Boom generation.
Same family: the Soundcore Boom 2 (smaller model, rated 4.5/5).
Pros: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Measured bass extension of 39Hz (-10dB).
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
