These are not really the same size class, and that is the honest framing here. The Devialet Mania ranks #54 of 117 large speakers by sound quality at $899; the JBL Authentics 300 ranks #46 of 112 boombox speakers by sound quality at $299.95.
The Devialet Mania is the lighter, tougher choice. A compact, good looking Wi-Fi and Bluetooth stereo speaker with Alexa built in and splash resistance. At 5.1 lbs (2.3 kg) it weighs much less than the JBL Authentics 300 at 10.8 lbs (4.9 kg). It is rated IPX4, while the JBL Authentics 300 has no water resistance. It keeps a wired aux input, which the JBL Authentics 300 lacks. The catch: Not very loud.
What the JBL Authentics 300 does well: A retro styled smart speaker with both Alexa and Google Assistant, a leather handle and battery power. It links with other speakers (Wi-Fi Multi-Room), which the Devialet Mania cannot. It has an adjustable EQ, which the Devialet Mania lacks. Watch for: Narrow sounding, bass not as deep as others.
Buy the Devialet Mania at $899 for a large speaker, or the JBL Authentics 300 at $299.95 for a boombox speaker instead.
