Short answer: the Soundcore Motion Boom+ for raw output, the Sony ULT Field 7 for the better tuning. The Motion Boom+ runs 80W stereo from dual 30W woofers and dual 10W tweeters with titanium drivers, but its default presets are all warm with rolled off treble. The Sony is called better sounding than the XG500, with bass that is still not as deep as the top ranked speakers.
Buy the Sony ULT Field 7. It is rated higher for sound quality; the Soundcore Motion Boom+ is no longer sold new.

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.
