Short answer: the Demerbox DB2 for better sound quality, the EcoXGear Defender for the lower price. The Demerbox DB2 ranks #49 of 73 boombox speakers at $400. The EcoXGear Defender ranks #57 at $260, $140 cheaper.
What the Demerbox DB2 offers: Built from an actual Pelican case, so it’s nearly indestructible and waterproof (IP67), plus multi-pair up to 6 units. Watch for: Bass isn’t as deep as better speakers, and it’s expensive for what it does.
What the EcoXGear Defender offers: A claimed 121dB output for less money, a built-in flashlight and bottle opener, and it floats. Watch for: Bass isn’t as deep as the class’s better competitors.
Buy the Demerbox DB2 if sound quality matters more than the price. Buy the EcoXGear Defender if the price matters more than sound quality.
If sound quality matters at all to you, skip the EcoXGear Defender. It ranks near the bottom of the 73 boombox speakers, so look higher up the list instead.
