Short answer: the W-King T9. It ranks #41 of 82 large speakers by sound quality, rated 3.6/5, at $130. The Doss Extreme Boom ranks #80, rated 2.1/5, at $79.99, $50.01 cheaper, which does not close the gap in sound quality.
What the W-King T9 does well: 80W output power, 106dB max volume, 24-hour battery life, power bank function, Bluetooth 5.3 with 100ft range, TWS stereo pairing with wireless microphone, dual subwoofers, RGB lighting, MicroSD and AUX support, USB-C charging, karaoke capability. Watch for: Peaks in the upper mids which makes it sound a bit harsh.
The case for the Doss Extreme Boom: A durable 2.52kg outdoor speaker with claimed 60W output, IPX7 protection, USB-C charging, aux and microSD playback, speakerphone capability, a power bank and TWS pairing. The catch: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing.
Buy the W-King T9. It is rated higher for sound quality, and the $50.01 saving on the Doss Extreme Boom is not enough to make up the difference.
There is a real gap in water resistance: the Doss Extreme Boom at IPX7 (brief submersion) against the W-King T9, which has no water resistance.

Doss Extreme Boom: $79.99 Amazon eBay
Pros: A durable 2.52kg outdoor speaker with claimed 60W output, IPX7 protection, USB-C charging, aux and microSD playback, speakerphone capability, a power bank and TWS pairing. It offers long claimed battery life and can play loudly enough for a casual party, with a bass-heavy sound that carries outdoors. Measured bass extension of 65Hz (-10dB).
Cons: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing. Reviews describe fuzzy mids, mushy bass when pushed and rolled-off treble, while there is no app or EQ to restore balance. It is best for loud background music, not clear or refined listening.
