These are not really the same size class, and that is the honest framing here. The Marshall Stockwell II ranks #11 of 120 large speakers by sound quality at $229.99; the Zealot ZE41 ranks #17 of 113 boombox speakers by sound quality at $219.95.
The Marshall Stockwell II is the longer-running, lighter choice. A light, strap equipped speaker with some of the most natural sound around, even off to the side, and a long battery. It is rated for 20 hours of battery against 4 for the Zealot ZE41. At 3.1 lbs (1.4 kg) it weighs much less than the Zealot ZE41 at 25.3 lbs (11.48 kg). The catch: Not very loud, and the added DSP reverb may annoy purists.
What the Zealot ZE41 does well: A huge boombox with lots of bass, volume and play time for the money. It links with other speakers (PartyAdd up to 100 speakers), which the Marshall Stockwell II cannot. It has an adjustable EQ, which the Marshall Stockwell II lacks. It plays in stereo from a single unit, unlike the Marshall Stockwell II. The tradeoff: The heaviest and biggest boombox speaker around.
Buy the Marshall Stockwell II at $229.99 if you want a large speaker. Buy the Zealot ZE41 at $219.95 if you want a boombox speaker instead.
