Zealot ZE41: $219.95 Aliexpress Amazon

Zealot ZE41 ranking card

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 isnโ€™t as good as better speakers. Bass EQ is bloated and muddy sounding.
