Short answer: the Soundcore Boom 2 Plus if weight matters, the Zealot ZE51 for cleaner detail. The Boom 2 Plus is quite a bit lighter than most boombox-size speakers and its bass is reasonably deep, but its warm tuning rolls off the treble and adds some upper bass boost. The ZE51 is cleaner and wider than the ZE41 with less distortion at volume, at the cost of being large and heavy.
Buy the Zealot ZE51. It is rated higher for sound quality, and the $116.40 saving on the Soundcore Boom 2 Plus is not enough to make up the difference.
If battery life is a priority, the Soundcore Boom 2 Plus is rated for 20 hours versus 4 hours for the Zealot ZE51.

Pros: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity.
Cons: 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.

Soundcore Boom 2 Plus: $179.99 Amazon $179.99 Lowest Soundcore $249.99 eBay
Older model: the Soundcore Motion Boom+ (ranked lower, rated 2.9/5). See every Soundcore Boom generation.
Same family: the Soundcore Boom 2 (smaller model, rated 4.5/5).
Pros: 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. Measured bass extension of 39Hz (-10dB).
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
