Short answer: the Zealot ZE41, which the notes call the absolute best value in the boombox class for bass performance, play time and max volume. The tradeoff is size: it is the heaviest and biggest boombox around. The Aiwa Exos-9 still sounds great against today’s models, but it is no longer sold new, its features are lacking, and it is generally not recommended anymore.

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.
There is a real battery-life gap here: the Aiwa Exos-9 is rated for 10 hours, the Zealot ZE41 only 4 hours.
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: $259.90 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.
