Short answer: the Zealot ZE51. It ranks #16 of 112 boombox speakers by sound quality, rated 4.1/5, at $235.33. The W-King D10 ranks #79, rated 2.7/5, at $84.97, $150.36 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Zealot ZE51 is the better-sounding option. A big stereo boombox with clean, wide sound and low distortion at high volume for outdoor parties. The catch: The Zealot ZE41 still wins on raw bass depth and price.
The W-King D10 is the longer-running, lighter choice. An inexpensive boombox with a 42 hour battery, water resistance, a power bank and a karaoke mic input. It is rated for 42 hours of battery against 4 for the Zealot ZE51. At 7.9 lbs (3.6 kg) it weighs much less than the Zealot ZE51 at 26 lbs (11.81 kg). Watch for: Upper bass boost, bass not that deep.
Buy the Zealot ZE51. It is rated higher for sound quality, and the $150.36 saving on the W-King D10 is not enough to make up the difference.
