Short answer: the JBL Boombox 3 Wifi. It ranks #26 of 112 boombox speakers by sound quality (rated 3.8/5) at $389.95 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 JBL Boombox 3 Wifi is the better-sounding option. A big, waterproof stereo boombox with Wi-Fi, a long battery and enough volume for any outdoor party. The tradeoff: Bass boosted.
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 JBL Boombox 3 Wifi. At 5.4 lbs (2.47 kg) it weighs much less than the JBL Boombox 3 Wifi at 14.6 lbs (6.6 kg). Watch for: Bass is not as deep as better speakers.
Buy the JBL Boombox 3 Wifi. It is rated higher for sound quality and still sold new, while the Demerbox DB2 is discontinued.
