Short answer: the Zealot ZE51. It ranks #16 of 112 boombox speakers by sound quality (rated 4.1/5) at $235.33 and is still sold new; the Bumpboxx Flare 6 ranks #82 (rated 2.6/5) and is discontinued, so it is only an option used.
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. It has an adjustable EQ, which the Bumpboxx Flare 6 lacks. The catch: The Zealot ZE41 still wins on raw bass depth and price.
The Bumpboxx Flare 6 is the longer-running, lighter option. A retro styled stereo party speaker with water resistance and a 12 hour battery. It is rated for 12 hours of battery against 4 for the Zealot ZE51. At 13 lbs (5.9 kg) it weighs much less than the Zealot ZE51 at 26 lbs (11.81 kg).
Buy the Zealot ZE51. It is rated higher for sound quality; the Bumpboxx Flare 6 is no longer sold new.
