Short answer: the ZE41, and our own notes on the ZE21 admit it. The ZE21’s pros entry credits it with great value for bass, play time, and max volume in the boombox class, then adds that the ZE41 now beats it out. It ranks #16 of 75 boombox speakers at $259.90; the ZE21 ranks #17 at $247.41, $12.49 less.
The complaints are nearly identical between them. Both share a top end that’s rolled off and not well balanced against the rest of the range, and a bass EQ our notes call bloated and muddy sounding. The ZE41 adds one more: it’s the heaviest and biggest boombox speaker in the class.
The ZE41’s edge is narrow but real, described in our notes as the absolute best value for bass, play time, and max volume, upgraded from the ZE21’s merely great version of the same claim.
Buy the ZE41 if the extra size and weight aren’t a dealbreaker. Buy the ZE21 to save $12.49 and accept a small step down from what is, by our own account, now the better speaker.
There is a real battery-life gap here: the Zealot ZE21 is rated for 40 hours, the Zealot ZE41 only 4 hours.

The Two Speakers In Full
Zealot ZE21: $187.15 Amazon Aliexpress eBay
Pros: The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. Its TWS button can form a stereo pair with another compatible Zealot, and its large, rugged chassis gives it credible party-speaker scale. Measured bass extension of 36Hz (-10dB).
Cons: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy. The supplied sound modes do not fully correct the tuning; the most positive independent report required source-side parametric EQ. Treble is also soft and clarity trails better-tuned rivals.

Zealot ZE41: $259.90 Amazon Aliexpress eBay
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 isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.
