Short answer: the Yeahbox Sonic Boom Max 3. It ranks #59 of 113 boombox speakers by sound quality, rated 3.2/5, at $228.99; the EcoXGear Defender ranks #85, rated 2.5/5, and costs $299.99, so there is not much of a tradeoff to weigh.
On the EcoXGear Defender side: 121dB output for $299.99. IP67 waterproof/dustproof, floats. The catch: Bass not as deep as competitors.
The case for the Yeahbox Sonic Boom Max 3: 200W RMS (300W peak) true 3-way, 5-driver array. The tradeoff: A budget import brand with limited independent testing - specs are manufacturer-claimed.
Buy the Yeahbox Sonic Boom Max 3. It is rated higher for sound quality than the EcoXGear Defender and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
