Zealot S89: $193.58 Aliexpress Amazon
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
