Short answer: the W-King D10, if you are buying new, though neither ranks well in its class. The Demerbox DB2 ranks higher than it (#74 vs #79 of 112 boombox speakers, 2.8/5 vs 2.7/5) but is discontinued, so only consider it used; the W-King D10 is still sold new at $84.97. Both are rated below 3.0/5 among the 112 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $179.99.
The case for the W-King D10: An inexpensive boombox with a 42 hour battery, water resistance, a power bank and a karaoke mic input. It has an adjustable EQ, which the Demerbox DB2 lacks. Watch for: Upper bass boost, bass not that deep.
The Demerbox DB2 is the lighter pick. A nearly indestructible waterproof speaker built from a Pelican case, with a 40 hour battery and dry storage. At 5.4 lbs (2.47 kg) it weighs noticeably less than the W-King D10 at 7.9 lbs (3.6 kg). The catch: Bass is not as deep as better speakers.
Buy the W-King D10 new; the Demerbox DB2 is no longer sold new, so it only makes sense as a used find.
