Short answer: the JBL Partybox Encore Essential. It ranks #8 of 89 boombox speakers by sound quality, rated 4.2/5, at $329.95. The Ruimatech RM-10 ranks #28, rated 3.8/5, at $159.99, $169.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the JBL Partybox Encore Essential: JBL Partybox Encore Essential uses 135mm woofer + 2x 44mm tweeters. The catch: Bass is limited by its 38Hz specification.
What the Ruimatech RM-10 does well: 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. The tradeoff: It is tuned bass boosted, much like the JBL Boombox 3.
Buy the JBL Partybox Encore Essential. It is rated higher for sound quality, and the $169.96 saving on the Ruimatech RM-10 is not enough to make up the difference.
If battery life is a priority, the Ruimatech RM-10 is rated for 14 hours versus 6 hours for the JBL Partybox Encore Essential.

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.
