These are not really the same size class, and that is the honest framing here. The Zealot ZE41 ranks #17 of 113 boombox speakers by sound quality at $219.95; the Marshall Middleton II ranks #31 of 120 large speakers by sound quality at $279.99.
Why pick the Zealot ZE41: A huge boombox with lots of bass, volume and play time for the money. The tradeoff: The heaviest and biggest boombox speaker around.
The Marshall Middleton II is the longer-running, lighter pick. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and an app EQ. It is rated for 30 hours of battery against 4 for the Zealot ZE41. At 4 lbs (1.8 kg) it weighs much less than the Zealot ZE41 at 25.3 lbs (11.48 kg). It is rated IP67 against IPX5 for the Zealot ZE41. The tradeoff: Bass boosted which drowns out the midrange.
Buy the Zealot ZE41 at $219.95 for a boombox speaker, or the Marshall Middleton II at $279.99 for a large speaker instead.
