Short answer: the Zealot ZE51 if sound quality matters most, the Soundcore Boom 2 Plus if price matters most. The Zealot ZE51 ranks #14 of 74 boombox speakers at $296.39. The Soundcore Boom 2 Plus ranks #27 at $169.99, $126.40 cheaper.
What the Zealot ZE51 gets right: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity. The tradeoff: The Zealot ZE41 still wins on raw bass depth and price. Large and heavy like the rest of the boombox class, and clarity still isn’t up to dedicated hi-fi speakers.
What the Soundcore Boom 2 Plus offers: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Set against that: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
Buy the Zealot ZE51 if sound quality is the priority over the price, or the Soundcore Boom 2 Plus if the price is the priority over sound quality.
