Short answer: the JBL Boombox 4 if sound quality matters most, the Ruimatech RM-10 if price matters most. The JBL Boombox 4 ranks #20 of 89 boombox speakers, rated 4.0/5, at $549.95. The Ruimatech RM-10 ranks #28, rated 3.8/5, at $159.99, $389.96 cheaper.
The case for the JBL Boombox 4: Pretty insane output capability for the size. Watch for: Pretty overpriced for the category.
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 Boombox 4 if sound quality is the priority over the price, or the Ruimatech RM-10 if the price is the priority over sound quality.

Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5).
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
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.

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.
