Short answer: the EcoXGear Defender, if you are buying new, though neither ranks well in its class. The Demerbox DB2 ranks higher than it (#64 vs #72 of 89 boombox speakers, 2.8/5 vs 2.5/5) but is discontinued, so only consider it used; the EcoXGear Defender is still sold new at $299.99. Both are rated below 3.0/5 among the 89 boombox speakers, and the Tribit Stormbox Blast, ranked #2 at $179.99, is a better place to start if sound quality matters.
The Demerbox DB2 is the longer-running, lighter pick. 40+ hour battery life even at higher volumes (real-world: ~14 hrs with phone charging mixed in). It is rated for 40 hours of battery against 25 for the EcoXGear Defender. At 5.4 lbs (2.47 kg) it weighs much less than the EcoXGear Defender at 10 lbs (4.54 kg). It plays in stereo from a single unit, unlike the EcoXGear Defender. The catch: Bass is not as deep as better speakers.
The case for the EcoXGear Defender: A rugged 10 lbs (4.54 kg) outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. It has an adjustable EQ, which the Demerbox DB2 lacks. The catch: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited.
Buy the EcoXGear Defender, since the Demerbox DB2 is discontinued and only worth hunting down used.

EcoXGear Defender: $299.99 Amazon eBay
Pros: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. Independent testing found it gets very loud for its size, while its three ecoEQ presets let you choose a bass-heavy default, a more balanced indoor mode or a brighter outdoor mode.
Cons: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited. The default setting can be over-bassy at lower volumes, while there is no app, precise EQ, battery indicator or multi-speaker party mode. Bass does not reach as deep as competitors.
