Short answer: the Yeahbox Sonic Boom Max 3 is the more flexible three-way party speaker, while the Zealot ZE41 is the brute-force bass and output value. Yeahbox provides a five-driver layout, 200W RMS, 111Wh battery, USB-C fast charging, app EQ, TWS, aux, USB, and microSD playback. ZE41 uses a much larger 140W subwoofer and is positioned as a class leader for bass, play time, and maximum volume.
The Yeahbox has limited independent testing and inconsistent water-rating claims, so its impressive specification sheet needs caution. ZE41 is better documented as a big, heavy boombox, but its treble rolls off and its overall balance is less refined; bass EQ can also introduce distortion.
Buy the Yeahbox Sonic Boom Max 3 for its broad playback options, app control, and three-way driver configuration.
Buy the Zealot ZE41 for maximum bass and output per dollar if you can accommodate its size and weight.
