Short answer: the W-King X20. It ranks #31 of 76 boombox speakers by sound quality, rated 3.5/5, at $219.98. The onn Pro X Large Boom Boombox ranks #35, rated 3.4/5, at $199, $20.98 cheaper, which does not close the gap in sound quality.
Why pick the W-King X20: 200W RMS output with 330W peak power, 112dB max volume, exceptional 24-hour battery life with power bank, IPX6 waterproof, EQ with app control and button modes, 7.5-inch subwoofer, Bluetooth 5.3, dual pairing, MicroSD and USB playback, AUX input, TWS stereo mode with 240W combined. The catch: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
The case for the onn Pro X Large Boom Boombox: High rated power for the price at 180W RMS (540W peak). Watch for: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
Buy the W-King X20. It is rated higher for sound quality, and saving $20.98 with the onn Pro X Large Boom Boombox does not make up for the sound-quality gap.
