Short answer: the Tribit Stormbox Blast. It ranks #2 of 113 boombox speakers by sound quality, rated 4.5/5, at $199.99. The W-King X20S ranks #30, rated 3.8/5, at $150.99, $49 cheaper, which does not close the gap in sound quality.
The Stormbox Blast is the proven one. It is quite neutral, reaches about 43Hz and measured about 108dB, and it improves further with the Oluv EQ linked on its page.
The X20S is clear with plenty of bass for its size, but its bass is cut off on a flat EQ and its mids and highs dominate at max volume. Its rating comes from listening comparisons, not measurements.
Features: the Blast claims 30 hours with IPX7 and lights. The X20S is IPX7 with FM radio, TF and USB playback, a built-in microphone and a shoulder strap.
Buy the Tribit Stormbox Blast. It is rated higher for sound quality, and saving $49 with the W-King X20S does not make up for the sound-quality gap.
