Short answer: the Yeahbox Sonic Boom Max 3. It ranks #37 of 70 boombox speakers at $228.99; the EcoXGear Defender ranks #56 and costs $260, so there is not much of a tradeoff to weigh.
On the EcoXGear Defender side: 121dB output for $250. 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 EcoXGear Defender if the price matters more than the ranking. Buy the Yeahbox Sonic Boom Max 3 if the ranking matters more than the price.
