#18 Zealot S89: $246.99 Amazon Aliexpress eBay

Pros: A great value for the bass performance, play time and max volume in the boombox class. Likely the same internals as the Zealot ZE21

Cons: On the heavy side. 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

How it compares: Just above it: Zealot ZE21. Just below it: JBL Boombox 4 - $303 more, 12 fewer hours of battery life.
