Short answer: the onn Pro X Large Boom Boombox. It ranks #43 of 89 boombox speakers by sound quality, rated 3.4/5, at $199. The Soundcore Motion Boom+ ranks #62, rated 2.9/5, at $122.42, $76.58 cheaper, which does not close the gap in sound quality.
What the onn Pro X Large Boom Boombox does well: High rated power for the price at 180W RMS (540W peak). The catch: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.

One note: the Soundcore Motion Boom+ is no longer in production and isn’t widely stocked new anymore.
Buy the onn Pro X Large Boom Boombox. It is rated higher for sound quality, and the $76.58 you would save on the Soundcore Motion Boom+ does not close the gap.

Soundcore Motion Boom+: $122.42 after $40 coupon Discontinued Amazon eBay
Newer model: the Soundcore Boom 2 Plus, ranked higher, rated 3.6/5.
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 Motion Boom and a lot less deep bass than other speakers in the class. Discontinued.
