Short answer: the Zealot ZE41. It ranks #17 of 91 boombox speakers by sound quality (rated 4.1/5) at $259.90 and is still sold new; the Teufel Boomster 2021 ranks #46 (rated 3.4/5) and is discontinued, so it is only an option used.
The Zealot ZE41 is the better-sounding option. The absolute best value for the bass performance, play time and max volume in the boombox class. It links with other speakers (PartyAdd up to 100 speakers), which the Teufel Boomster 2021 cannot. It has an adjustable EQ, which the Teufel Boomster 2021 lacks. Watch for: The heaviest and biggest boombox speaker around.
The Teufel Boomster 2021 is the longer-running, lighter choice. It is rated for 18 hours of battery against 4 for the Zealot ZE41. At 8.3 lbs (3.75 kg) it weighs much less than the Zealot ZE41 at 25.3 lbs (11.48 kg). It is rated IPX7 against IPX5 for the Zealot ZE41.
Buy the Zealot ZE41. It is rated higher for sound quality, and the Teufel Boomster 2021 is discontinued, so it is only available used.

The Two Speakers In Full
Zealot ZE41: $259.90 Amazon AliExpress eBay
Pros: The absolute best value for the bass performance, play time and max volume in the boombox class.
Cons: The heaviest and biggest boombox speaker around. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.
