Zealot ZE21: $187.15 Aliexpress Amazon
Pros: Great value for the bass performance, play time and max volume in the boombox class, though the Zealot ZE41 now beats it out.
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. Bass EQ is bloated and muddy sounding
