Short answer: the W-King X20. It ranks #41 of 98 boombox speakers by sound quality (rated 3.5/5) at $229.99 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 W-King X20 is the better-sounding, deeper-bass pick. Its bass reaches about 42Hz before falling 10dB, against 52Hz for the Soundcore Motion Boom+. Alan Ross Reviews measured it at 112dB at full volume, against 108dB for the Soundcore Motion Boom+. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
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 W-King X20 at 15.9 lbs (7.2 kg). It links with other speakers (PartyCast up to 100 speakers), which the W-King X20 cannot. The catch: Default presets are all warm sounding with rolled off treble.
Buy the W-King X20. It is rated higher for sound quality, and the Soundcore Motion Boom+ is discontinued, so it is only available used.

Soundcore Motion Boom+: $122.42 after $40 coupon Discontinued Amazon $122.42 eBay
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.
