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 Soundbox XL ranks #80, rated 3.1/5, at $79.99, $31.24 cheaper, a saving that is not big enough to make up the sound-quality gap.
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 55Hz for the DOSS Soundbox XL. Alan Ross Reviews measured it at 106dB at full volume, against 100dB for the DOSS Soundbox XL. It is rated for 24 hours of battery against 10 for the DOSS Soundbox XL. The catch: Peaks in the upper mids which makes it sound a bit harsh.
The DOSS Soundbox XL is the lighter, tougher pick. A light, affordable speaker with a built in subwoofer, splash resistance, microSD playback, and stereo pairing. At 1.2 lbs (557 g) it weighs much less than the W-King T9 at 10.1 lbs (4.6 kg). It is rated IPX4, while the W-King T9 has no water resistance. Watch for: A little hollow sounding.
Buy the W-King T9. It is rated higher for sound quality, and the $31.24 you would save on the DOSS Soundbox XL does not close the gap.
