Pros

  • A larger driver array delivers fuller sound for open-plan rooms
  • The same Wi-Fi, Bluetooth and three-assistant feature set as the 200
  • Retro styling carried into a larger enclosure

Cons

Skip it if

Skip it if the speaker will sit on a shelf in a small room, where the Authentics 200 is enough, or if you want the most compact option in the range.

How we assessed it

We synthesized this

The JBL Authentics 300 takes the same smart-speaker brains as the 200 and gives them room to breathe. A larger driver array delivers fuller, roomier sound built for open-plan living and dining spaces, while the Wi-Fi multi-room, Bluetooth and three-assistant support — Alexa, Google Assistant and Siri — carry over unchanged. If you want one retro speaker to fill an open living area and run whichever voice assistant you already use, this is the pick in the range.

The trade-off is size: that larger enclosure is more than a small room needs, and on a single shelf or in a compact space the smaller Authentics 200 does the job just as well. Our read is a synthesis of JBL's documented specs and general use, not a hands-on listening test — see how we test.
