Short answer: the Zealot ZE41. It ranks #17 of 112 boombox speakers by sound quality (rated 4.1/5) at $219.95 and is still sold new; the Demerbox DB2 ranks #74 (rated 2.8/5) and is discontinued, so it is only an option used.
The Zealot ZE41 is the better-sounding pick. A huge boombox with lots of bass, volume and play time for the money. It links with other speakers (PartyAdd up to 100 speakers), which the Demerbox DB2 cannot. It has an adjustable EQ, which the Demerbox DB2 lacks. Watch for: The heaviest and biggest boombox speaker around.
The Demerbox DB2 is the longer-running, lighter choice. A nearly indestructible waterproof speaker built from a Pelican case, with a 40 hour battery and dry storage. It is rated for 40 hours of battery against 4 for the Zealot ZE41. At 5.4 lbs (2.47 kg) it weighs much less than the Zealot ZE41 at 25.3 lbs (11.48 kg). It is rated IP67 against IPX5 for the Zealot ZE41. Watch for: Bass is not as deep as better speakers.
Buy the Zealot ZE41. It is rated higher for sound quality and still sold new, while the Demerbox DB2 is discontinued.
