These are not really the same size class, and that is the honest framing here. The Zealot ZE41 ranks #17 of 76 boombox speakers by sound quality at $259.90; the Marshall Middleton II ranks #31 of 82 large speakers by sound quality at $330.
Why pick the Zealot ZE41: The absolute best value for the bass performance, play time and max volume in the boombox class. The tradeoff: The heaviest and biggest boombox speaker around.
The case for the Marshall Middleton II: Very deep bass for the size/weight. The catch: Bass boosted which drowns out the midrange.
Buy the Zealot ZE41 at $259.90 for a boombox speaker, or the Marshall Middleton II at $330 for a large speaker instead.
If battery life is a priority, the Marshall Middleton II is rated for 30 hours versus 4 hours for the Zealot ZE41.

The Two Speakers In Full
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.

Marshall Middleton II: $330 Amazon eBay
Older model: the Marshall Middleton (rated 4/5).
Pros: Very deep bass for the size/weight. Measured bass extension of 38Hz (-10dB).
Cons: Bass boosted which drowns out the midrange. Dip around 200Hz, peak at 1kHz, dipped at 1.6kHz. Strange frequency response through the mids.
