Short answer: these aren’t really competing for the same job. The Authentics 500 is $600 and has no battery at all; the Boombox 3 is $399, runs 24 hours on battery, and survives full submersion. Picking between them is really picking a use case first.
The Authentics 500 is JBL’s home lifestyle line. It ranks #3 of 6 in its powered desktop category, a small field, with 270W of output and genuinely deep bass for its size. It plugs into a wall and stays there. Its cons are typical JBL house tuning: boosted upper bass and peaky upper mids.
The Boombox 3 is built to leave the house. It ranks #23 of 75 portable boombox speakers, doubles as a USB power bank, and links up to 100 compatible JBL speakers over PartyBoost. Its own weak points are dips in the mid bass and a peak at 700 Hz that our notes say hold it back from the Stormbox Blast’s mids and treble.
Price aside, the decision is really about batteries and water. If it’s staying on a shelf near an outlet, the Authentics 500’s extra output and cleaner design make sense. If it needs to survive a pool deck or a yard, only the Boombox 3 is built for that.
Buy the Authentics 500 for a stationary home speaker with real output. Buy the Boombox 3 if you need it to run on battery, get wet, and travel.
There is a real gap in water resistance: the JBL Boombox 3 at IP67 (brief submersion) against the JBL Authentics 500, which has no water resistance.

JBL Authentics 500: $600 each Amazon eBay
Pros: JBL Authentics 500 uses 6.5” (down-firing subwoofer), 3x 2.75” midranges, 3x 1” (25mm aluminum dome) tweeters. Its 7.8 kg, aux input and stereo playback make it a practical option for its intended room or portable use.
Cons: Its 40Hz - 20kHz (-6dB) (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
