Short answer: the Zealot ZE21. It ranks #18 of 112 boombox speakers by sound quality (rated 4.0/5) at $187.15 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 ZE21 is the better-sounding, longer-running choice. A rugged battery boombox with unusually deep bass, very long battery life, and stereo pairing for party scale sound. It is rated for 40 hours of battery against 12 for the Bumpboxx Flare 6. It links with other speakers (PartyAdd up to 100 speakers), which the Bumpboxx Flare 6 cannot. It has an adjustable EQ, which the Bumpboxx Flare 6 lacks. The tradeoff: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy.
The Bumpboxx Flare 6 is the lighter pick. A retro styled stereo party speaker with water resistance and a 12 hour battery. At 13 lbs (5.9 kg) it weighs noticeably less than the Zealot ZE21 at 20.4 lbs (9.27 kg).
Buy the Zealot ZE21. It is rated higher for sound quality and still sold new, while the Bumpboxx Flare 6 is discontinued.
