These are not really the same size class, and that is the honest framing here. The JBL Partybox 130 ranks #7 of 40 party speakers by sound quality at $449.95; the Harman Kardon Onyx Studio 9 ranks #15 of 76 boombox speakers by sound quality at $189.99.
Why pick the JBL Partybox 130: A relatively manageable 11.3kg PartyBox with removable battery, foldable handle, light show, USB audio and modern JBL connectivity. The catch: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons.
Why pick the Harman Kardon Onyx Studio 9: An elegant 4.2kg living-room portable with a measured 41Hz -10dB bass point, 101dB maximum level, three tweeters, app EQ, stereo pairing and Auracast multi-speaker linking. Watch for: It has no water resistance, aux input or USB playback, and its eight-hour claimed battery life is short for an outdoor portable.
Buy the JBL Partybox 130 ($449.95) for a party speaker; the Harman Kardon Onyx Studio 9 ($189.99) suits a boombox speaker instead.
If water resistance matters to you, the JBL Partybox 130 at IPX4 (splashing) holds up far better than the Harman Kardon Onyx Studio 9 at no water resistance.

The Two Speakers In Full
JBL Partybox 130: $449.95 Amazon eBay
Pros: A relatively manageable 11.3kg PartyBox with removable battery, foldable handle, light show, USB audio and modern JBL connectivity. Independent reviews describe it as unusually balanced and powerful for its format, while owner feedback praises clear voices and deep bass.
Cons: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons. The smaller battery and stripped-back controls/features make it a questionable upgrade when the 120 is similarly priced. JBL’s wired daisy chain only works with other JBL speakers.

Harman Kardon Onyx Studio 9: $189.99 Amazon eBay
Older models: the Harman Kardon Onyx Studio 8 (rated 4.1/5), the Harman Kardon Onyx Studio 7 (rated 4.1/5), the Harman Kardon Onyx Studio 6 (rated 4.1/5), the Harman Kardon Onyx Studio 5 (rated 3.9/5) and the Harman Kardon Onyx Studio 4 (rated 3.3/5).
Pros: An elegant 4.2kg living-room portable with a measured 41Hz -10dB bass point, 101dB maximum level, three tweeters, app EQ, stereo pairing and Auracast multi-speaker linking. Reviews praise its balanced, smooth presentation and non-fatiguing treble, making it a more music-focused choice than most party speakers. Measured bass extension of 41Hz (-10dB).
Cons: It has no water resistance, aux input or USB playback, and its eight-hour claimed battery life is short for an outdoor portable. Bass is less deep than some earlier Onyx Studio models, while the slightly recessed mids and rolled-off top end mean it is not the most open or detailed option; it still charges from an AC power cable rather than USB-C.
