Short answer: the JBL Authentics 300. It ranks #44 of 98 boombox speakers by sound quality, rated 3.5/5, at $499.95. The W-King X10-1 ranks #84, rated 2.4/5, at $139.99, $359.96 cheaper, which does not close the gap in sound quality.
The JBL Authentics 300 is the better-sounding, deeper-bass option. Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). Its bass reaches about 45Hz before falling 10dB, against 63Hz for the W-King X10-1. It links with other speakers (Wi-Fi Multi-Room), which the W-King X10-1 cannot. Watch for: Narrow sounding, bass not as deep as others.
The W-King X10-1 is the louder, longer-running choice. Alan Ross Reviews measured it at 108dB at full volume, against 100dB for the JBL Authentics 300. It is rated for 42 hours of battery against 8 for the JBL Authentics 300. At 6.5 lbs (2.95 kg) it weighs much less than the JBL Authentics 300 at 10.8 lbs (4.9 kg). Watch for: Rolled off treble, not much bass.
Buy the JBL Authentics 300. It is rated higher for sound quality, and the $359.96 you would save on the W-King X10-1 does not close the gap.
Water resistance is not close: the W-King X10-1 is rated at IPX6 (powerful water jets), well ahead of the JBL Authentics 300 at no water resistance.
