Short answer: the JBL Partybox Club 120 if you move it around, the Harman Kardon Go + Play 2 otherwise. The Club 120 has a handle and wheels that make transport easy, but the source flags its high price. The Go + Play 2 is warm with boosted bass and not as loud as others, so it suits listeners who want richer tone rather than maximum output.
One note: the Harman Kardon Go + Play 2 is discontinued, but it still ranks #23 of 113 boombox speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used. The Harman Kardon Go + Play 2’s replacement, the Harman Kardon Go + Play 3, is rated 4.4/5 at $385.
Buy the Harman Kardon Go + Play 2 at $350 for a boombox speaker, or the JBL Partybox Club 120 at $399.95 for a party speaker instead.
Water resistance is not close: the JBL Partybox Club 120 is rated at IPX4 (splashing), well ahead of the Harman Kardon Go + Play 2 at no water resistance.
