Short answer: the JBL Xtreme 3. It ranks #18 of 105 large speakers by sound quality, rated 4.3/5, at $269.95. The W-King D9 ranks #91, rated 2.5/5, at $71.24, $198.71 cheaper, which does not close the gap in sound quality.
The JBL Xtreme 3 is the better-sounding option. Better treble and deeper bass than the JBL Xtreme 2. It links with other speakers (PartyBoost up to 100 speakers), which the W-King D9 cannot. Watch for: Boosted bass.
The W-King D9 is the deeper-bass, longer-running choice. A compact 4.4 lbs (2 kg) 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. Its bass reaches about 47Hz before falling 10dB, against 53Hz for the JBL Xtreme 3. It is rated for 40 hours of battery against 15 for the JBL Xtreme 3. Watch for: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
Buy the JBL Xtreme 3. It is rated higher for sound quality, and saving $198.71 with the W-King D9 does not make up for the sound-quality gap.

W-King D9: $71.24 Amazon $71.24 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.
