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

How it compares: Just above it: Zealot ZE41 - $33 more. Just below it: Zealot S89 - $6 more.
