Short answer: the W-King D9, though neither ranks well in its class. It ranks #70 of 82 large speakers by sound quality, rated 2.5/5, at $71.24; the Treblab HD-Max ranks #73, rated 2.4/5, and costs $129.97, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 82 large speakers; for better sound, the Tribit Stormbox Lava ranks #3 at $100.
The case for the W-King D9: A compact 2kg boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. The catch: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
Why pick the Treblab HD-Max: 50W incredibly loud for size with four monstrous drivers, tested 22.4-hour battery (25+ hours at 50% volume). The catch: Boosted upper bass, not much lower bass.
Buy the W-King D9. It is rated higher for sound quality than the Treblab HD-Max 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 D9: rated for 40 hours against 20 hours for the Treblab HD-Max.

The Two Speakers In Full
W-King D9: $71.24 Amazon eBay
Pros: A compact 2kg boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Long-term owners praise its loud, punchy character and useful indoor/outdoor voicing for casual outdoor listening. Measured bass extension of 47Hz (-10dB).
Cons: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume. There is no app or adjustable EQ, and its bass does not reach as deep as larger rivals, so it is better suited to energetic background music than neutral listening.
