These are not really the same size class, and that is the honest framing here. The JBL Partybox 130 ranks #7 of 53 party speakers by sound quality at $449.95; the Harman Kardon Onyx Studio 9 ranks #15 of 113 boombox speakers by sound quality at $184.99.
The JBL Partybox 130 is the longer-running, tougher option. A manageable party speaker with balanced, powerful sound, deep bass, a removable battery and a light show. It is rated for 15 hours of battery against 8 for the Harman Kardon Onyx Studio 9. It is rated IPX4, while the Harman Kardon Onyx Studio 9 has no water resistance. It keeps a wired aux input, which the Harman Kardon Onyx Studio 9 lacks. The tradeoff: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons.
The Harman Kardon Onyx Studio 9 is the lighter choice. An elegant living room portable with balanced, smooth, non-fatiguing sound, app EQ, and stereo pairing for music lovers. At 9.3 lbs (4.2 kg) it weighs much less than the JBL Partybox 130 at 24.9 lbs (11.3 kg). 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 ($184.99) suits a boombox speaker instead.
