Short answer: the Aiwa Exos-9. It ranks #8 of 75 boombox speakers by sound quality at $250; the Zealot ZE41 ranks #16 and costs $289.90, so there is little reason to consider the other one.
On the Aiwa Exos-9 side: Still a great sounding speaker even against today’s models. Set against that: Features are lacking, generally not recommended anymore, not sold new anymore.
The case for the Zealot ZE41: The absolute best value for the bass performance, play time and max volume in the boombox class. The tradeoff: The heaviest and biggest boombox speaker around.
Worth knowing: the Aiwa Exos-9 is discontinued, though it still ranks #8 of 75 boombox speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Aiwa Exos-9. It ranks higher for sound quality than the Zealot ZE41 and costs less, so the other one has nothing left to offer.
If water resistance matters to you, the Zealot ZE41 at IPX5 (water jets) holds up far better than the Aiwa Exos-9 at no water resistance.

Zealot ZE41: $289.90 Amazon Aliexpress eBay
Pros: The absolute best value for the bass performance, play time and max volume in the boombox class.
Cons: The heaviest and biggest boombox speaker around. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.
