Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Harman Kardon Go + Play 2 ranks #18 of 70 boombox speakers at $350; the JBL Partybox Club 120 ranks #4 of 44 party speakers at $349.95.
The case for the Harman Kardon Go + Play 2: Warm sound with boosted bass. The tradeoff: Not as loud as others.
What the JBL Partybox Club 120 gets right: Handle and wheels are convenient. Set against that: High price.
One note: the Harman Kardon Go + Play 2 is discontinued, but it still ranks #18 of 70 boombox speakers, ahead of most of what is still sold new, so it is worth considering used.
Buy the Harman Kardon Go + Play 2 at $350 if you want a boombox speaker. Buy the JBL Partybox Club 120 at $349.95 if you want a party speaker instead.
