Short answer: the JBL Boombox 4 for the higher ranking, the W-King X20 for the lower price. The JBL Boombox 4 ranks #17 of 70 boombox speakers at $549.95. The W-King X20 ranks #28 at $249.99, $299.96 cheaper.
On the JBL Boombox 4 side: Pretty insane output capability for the size. The tradeoff: Pretty overpriced for the category.
The case for the W-King X20: 200W RMS output with 330W peak power, 112dB max volume, exceptional 24-hour battery life with power bank, IPX6 waterproof. The catch: Rising frequency response but upper treble rolled off, 700hz and 1.2khz peaks.
Buy the JBL Boombox 4 if the ranking matters more than the price. Buy the W-King X20 if the price matters more than the ranking.

The Two Speakers In Full
JBL Boombox 4: $549.95 Amazon Bhphotovideo
Pros: Pretty insane output capability for the size.
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
