Short answer: the Ruimatech RM-10. It ranks #28 of 85 boombox speakers by sound quality, rated 3.8/5, at $159.99; the W-King X20 ranks #36, rated 3.5/5, and costs $219.98, so there is not much of a tradeoff to weigh.
In a side by side test the Ruimatech RM-10 sounded better in most ways. Its highs are cleaner, the mids are great and the overall clarity is more on point, which the reviewer put down to better tuning. It also reaches a little deeper in the bass.
The W-King X20 keeps more of its bass at 90 and 100 percent volume and plays a touch louder, so it still has the edge for flat out outdoor use. It also has an app with custom EQ and a larger claimed battery life, where the RM-10 has no app.
The RM-10 uses a three-way layout with an 80W woofer, two midranges and two tweeters plus dual passive radiators, rated IPX6 with a claimed 14 hours. Its build feels a bit cheaper, though the fabric wrap and thick plastic hold up well.
Buy the Ruimatech RM-10. It is rated higher for sound quality than the W-King X20 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Battery life favors the W-King X20: rated for 24 hours against 14 hours for the Ruimatech RM-10.

The Two Speakers In Full
Ruimatech RM-10: $159.99 Amazon eBay
Pros: A three-way boombox (80W woofer, two 20W midranges, two 10W tweeters and dual passive radiators, 140W RMS) with a hi-fi leaning clarity, highs that don’t get screechy at max volume, and bass that holds on at full volume. Side by side it beat the W-King X20S and X20 and sounded as good as the Tribit Stormbox Blast 2, especially at higher volume. IPX6, a claimed 14 hours, a USB-C power bank, 30W fast charging and stereo pairing.
Cons: It is tuned bass boosted, much like the JBL Boombox 3. There is no app or custom EQ and no shoulder strap, and the design is plain. The evidence is listening comparisons, not measurements.
