Short answer: the Tronsmart Force Max. It ranks #63 of 85 large speakers by sound quality, rated 3.0/5, at $119.99. The W-King D9 ranks #73, rated 2.5/5, at $89.99, $30 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Tronsmart Force Max does well: Two woofers, two tweeters and two passive radiators on opposite faces spread its 80W of sound all around it. Watch for: Sonido Pesado found the Tronsmart Halo 100 clearly better, with clearer mids and highs.
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.
Buy the Tronsmart Force Max. It is rated higher for sound quality, and the $30 you would save on the W-King D9 does not close the gap.
There is a real battery-life gap here: the W-King D9 is rated for 40 hours, the Tronsmart Force Max only 13 hours.

The Two Speakers In Full
Tronsmart Force Max: $119.99 Tronsmart eBay
Pros: Two woofers, two tweeters and two passive radiators on opposite faces spread its 80W of sound all around it. IPX6 water resistance, a 13 hour battery rating at half volume, a retractable strap, aux input, TF card and USB playback, a USB-C power bank, three EQ presets, a speakerphone microphone and stereo pairing.
Cons: Sonido Pesado found the Tronsmart Halo 100 clearly better, with clearer mids and highs. The Force Max’s mids are recessed and it audibly distorts near full volume, which Dominik Reviews put down to a poorly set limiter, and listeners preferred the Sony SRS-XB43 for balance. There is no app, it uses the older Bluetooth 5.0, and it weighs 2.54 kg.

W-King D9: $89.99 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.
