Short answer: the B&O Beolit 20. It ranks #42 of 89 boombox speakers by sound quality, rated 3.4/5, at $749. The Demerbox DB2 ranks #64, rated 2.8/5, at $400, $349 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the B&O Beolit 20: B&O Beolit 20 uses 2x 30mm tweeters + 2x 40mm mid-range + 1x 60mm woofer + dual passive radiators. The tradeoff: Bass is limited by its 45Hz specification.
Why pick the Demerbox DB2: 40+ hour battery life even at higher volumes (real-world: ~14 hrs with phone charging mixed in). The tradeoff: Bass is not as deep as better speakers.
One note: the Demerbox DB2 is discontinued and no longer widely available new.
Buy the B&O Beolit 20. It is rated higher for sound quality, and the $349 you would save on the Demerbox DB2 does not close the gap.
Water resistance is not close: the Demerbox DB2 is rated at IP67 (brief submersion), well ahead of the B&O Beolit 20 at IPX4 (splashing).
