Short answer: the Zealot ZE41 for output and value, unless you need something lighter. The ZE41 is the absolute best value for bass performance, play time and max volume in the boombox class, but it is the heaviest and biggest boombox speaker around. The Go + Play 2 is warm with boosted bass but is not as loud as others.
Buy the Zealot ZE41. It is rated higher for sound quality and still sold new, while the Harman Kardon Go + Play 2 is discontinued.
There is a real gap in water resistance: the Zealot ZE41 at IPX5 (water jets) against the Harman Kardon Go + Play 2, which has no water resistance.

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.
