Short answer: the Zealot S95. It ranks #24 of 73 boombox speakers by sound quality at $157.41; the JBL Authentics 300 ranks #30 and costs $299.95, so there is not much of a tradeoff to weigh.
The case for the Zealot S95: A good value for the boombox class. The tradeoff: A little rolled off up top and not that balanced through the rest of the range.
What the JBL Authentics 300 offers: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). Watch for: Narrow sounding, bass not as deep as others.
Buy the Zealot S95. It ranks higher for sound quality than the JBL Authentics 300 and costs less, so there is no real case for the other one.
If water resistance matters to you, the Zealot S95 at IPX6 (powerful water jets) holds up far better than the JBL Authentics 300 at no water resistance.

The Two Speakers In Full
Zealot S95: $157.41 Amazon Aliexpress
Pros: A good value for the boombox class. Appears to be the same internals as the ZE01. Bigger case and goes deeper than the ZE01
Cons: A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers.
