Short answer: the W-King T9. It ranks #53 of 120 large speakers by sound quality, rated 3.6/5, at $111.23. The DOSS Extreme Boom ranks #115, rated 2.1/5, at $75.99, $35.24 cheaper, which does not close the gap in sound quality.
The W-King T9 is the better-sounding, deeper-bass option. A loud stereo party speaker with a wireless microphone for karaoke, lights, a long battery and a power bank. Its bass reaches about 47Hz before falling 10dB, against 65Hz for the DOSS Extreme Boom. Watch for: Peaks in the upper mids which makes it sound a bit harsh.
The DOSS Extreme Boom is the lighter, tougher choice. An affordable waterproof outdoor speaker with a long rated battery, power bank output, and bass heavy sound for casual parties. At 5.6 lbs (2.52 kg) it weighs much less than the W-King T9 at 10.1 lbs (4.6 kg). It is rated IPX7, while the W-King T9 has no water resistance. The tradeoff: 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 $35.24 saving on the DOSS Extreme Boom is not enough to make up the difference.
