Short answer: the DOSS Soundbox XL. It ranks #80 of 120 large speakers by sound quality, rated 3.1/5, at $79.99; the W-King D9 ranks #98, rated 2.5/5, and costs $89.98, so there is not much of a tradeoff to weigh.
The DOSS Soundbox XL is the better-sounding, lighter choice. 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 D9 at 4.4 lbs (2 kg). The catch: A little hollow sounding.
The W-King D9 is the louder, deeper-bass choice. A compact, punchy boombox with a very long rated battery, water resistance, and power bank output for casual outdoor use. 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 40 hours of battery against 10 for the DOSS Soundbox XL. The tradeoff: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
Buy the DOSS Soundbox XL. It is rated higher for sound quality than the W-King D9 and costs less, so only choose the other one for a particular feature it does better.
