Short answer: the Zealot ZE51. It ranks #16 of 113 boombox speakers by sound quality, rated 4.1/5, at $235.33. The W-King T11 ranks #55, rated 3.3/5, at $116.57, $118.76 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Zealot ZE51 is the better-sounding choice. 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 T11 is the longer-running, lighter choice. A weather resistant party speaker with deep bass, high volume and a karaoke mic input. It is rated for 10 hours of battery against 4 for the Zealot ZE51. At 11.2 lbs (5.1 kg) it weighs much less than the Zealot ZE51 at 26 lbs (11.81 kg). The tradeoff: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
Buy the Zealot ZE51. It is rated higher for sound quality, and the $118.76 saving on the W-King T11 is not enough to make up the difference.
