Short answer: the Harman Kardon Citation 200, if bass depth matters most. It ranks #13 of 93 and its bass is deeper than any Onyx, though it is boomy by default. The Soundcore Select Pro costs $80 and sounds almost exactly like the Motion Boom, with boosted bass and rolled-off treble, making it the cheaper but less refined pick.
Buy the Harman Kardon Citation 200 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Tribit Stormbox Lava instead.
There is a real battery-life gap here: the Soundcore Select Pro is rated for 16 hours, the Harman Kardon Citation 200 only 8 hours.
Water resistance is not close: the Soundcore Select Pro is rated at IPX7 (brief submersion), well ahead of the Harman Kardon Citation 200 at IPX4 (splashing).

Soundcore Select Pro: $80 Discontinued eBay
Pros: A tough 1.5kg speaker with IPX7 protection, app EQ, a claimed 16-hour battery life, USB-C charging, power-bank output and PartyCast for linking up to 100 compatible speakers. It reaches a useful 106dB maximum level and offers a lively, bass-forward sound for casual outdoor use.
Cons: Independent lab listening finds only fair music fidelity: bass is somewhat boomy and lacks deep extension, mids can sound nasal and congested, and treble becomes smeared or sizzly. It strains at high volume, lacks an aux input and is discontinued, so it is best chosen for features and durability rather than detail or neutral sound.
