Short answer: the Zealot S89. It ranks #19 of 98 boombox speakers by sound quality (rated 4.0/5) at $246.99 and is still sold new; the Soundcore Motion Boom+ ranks #68 (rated 2.9/5) and is discontinued, so it is only an option used. The Soundcore Motion Boom+’s replacement, the Soundcore Boom 2 Plus, is rated 3.6/5 at $179.99.
The Zealot S89 is the better-sounding, deeper-bass 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. Its bass reaches about 36Hz before falling 10dB, against 52Hz for the Soundcore Motion Boom+. It is rated for 40 hours of battery against 20 for the Soundcore Motion Boom+. 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 Motion Boom+ is the lighter choice. 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. At 5.3 lbs (2.4 kg) it weighs much less than the Zealot S89 at 16.1 lbs (7.3 kg). Watch for: Default presets are all warm sounding with rolled off treble.
Buy the Zealot S89. It is rated higher for sound quality and still sold new, while the Soundcore Motion Boom+ is discontinued.

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.

Newer model: the Soundcore Boom 2 Plus, ranked higher, rated 3.6/5, released May 2024. It adds built-in mic and AAC. See every Soundcore Boom generation.
Pros: 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. 13,400mAh battery for 20 hours (12-15 at high volume). IP67 waterproof, floats, rugged build inspires confidence. Bluetooth 5.3 multipoint pairing, Soundcore app EQ, PartyCast 2.0 mode. USB-C input, USB-A output for powerbank. Measured bass extension of 52Hz (-10dB).
Cons: Default presets are all warm sounding with rolled off treble. Will need a custom EQ to get closer to neutral. A shrill sounding 6kHz peak comes out when volume is above about 60%. Not much deeper bass than a Soundcore Motion Boom and a lot less deep bass than other speakers in the class. Discontinued.
