Short answer: the W-King X20. It ranks #43 of 112 boombox speakers by sound quality (rated 3.5/5) at $219.98 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 W-King X20 is the better-sounding choice. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It has an adjustable EQ, which the Demerbox DB2 lacks. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
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 24 for the W-King X20. At 5.4 lbs (2.47 kg) it weighs much less than the W-King X20 at 15.9 lbs (7.2 kg). The tradeoff: Bass is not as deep as better speakers.
Buy the W-King X20. It is rated higher for sound quality and still sold new, while the Demerbox DB2 is discontinued.
