Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Xtreme 5 ranks #2 of 103 large speakers by sound quality at $399.95; the Harman Kardon Onyx Studio 6 ranks #13 of 91 boombox speakers by sound quality at $130.
The JBL Xtreme 5 is the louder, longer-running choice. Removable battery. Alan Ross Reviews measured it at 110dB at full volume, against 96dB for the Harman Kardon Onyx Studio 6. It is rated for 28 hours of battery against 8 for the Harman Kardon Onyx Studio 6. It supports AAC Bluetooth, which the Harman Kardon Onyx Studio 6 lacks. Watch for: High priced.
Why pick the Harman Kardon Onyx Studio 6: Harman Kardon Onyx Studio 6 uses a 120mm woofer, 25mm tweeter and passive radiator. It keeps a wired aux input, which the JBL Xtreme 5 lacks. The catch: Warm tuning with boosted bass, and not as loud as others.
Worth knowing: the Harman Kardon Onyx Studio 6 is discontinued, though it still ranks #13 of 91 boombox speakers by sound quality, so a used unit beats most of what is still sold new. The Harman Kardon Onyx Studio 6’s replacement, the Harman Kardon Onyx Studio 9, is still sold new.
Buy the JBL Xtreme 5 at $399.95 for a large speaker, or the Harman Kardon Onyx Studio 6 at $130 for a boombox speaker instead.

JBL Xtreme 5: $399.95 Amazon B&H Photo Video eBay
Older models: the JBL Xtreme 3 (ranked lower, rated 4.3/5), the JBL Xtreme 4 (ranked lower, rated 3.8/5), the JBL Xtreme 2 (ranked lower, rated 3.4/5) and the JBL Xtreme (ranked lower, rated 3.2/5). See every JBL Xtreme generation.
Pros: Removable battery. Quite deep bass, reaching well below 40Hz. A fantastic sounding speaker with excellent off-axis dispersion, a big step up from older JBL portables. Beats the Soundcore Boom 2 and Tribit Stormbox Blast on bass depth and clarity. Plays clean at volume, unlike the JBL Boombox 4.
Cons: High priced. Some bass boost. A hole in the mid-upper bass which can’t be EQ’d out. Default EQ presets are weak (Signature is boring, Chill and Vocal are close to unusable): needs the custom EQ to sound its best. Bigger and heavier than the JBL Xtreme 4.
Setup: Try this Oluv EQ for the most neutral sound

Harman Kardon Onyx Studio 6: $130 Discontinued Amazon eBay
Newer model: the Harman Kardon Onyx Studio 9, ranked lower, rated 4.1/5, released Dec 2024.
Older models: the Harman Kardon Onyx Studio 5 (ranked lower, rated 3.9/5) and the Harman Kardon Onyx Studio 4 (rated 3.3/5). See every Harman Kardon Onyx Studio generation.
Pros: Harman Kardon Onyx Studio 6 uses a 120mm woofer, 25mm tweeter and passive radiator. Its 2.94 kg, claimed 8 hours (Manufacturer specified) battery life, IPX7 protection, aux input and up to 96dB make it a practical option for its intended room or portable use. Measured bass extension of 37Hz (-10dB).
Cons: Bass is limited by its 37Hz specification. There is no companion app. No EQ adjustment. Warm tuning with boosted bass, and not as loud as others. Discontinued.
