Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Amazon Echo Dot Max ranks #5 of 14 powered desktop speakers by sound quality at $89.99; the JBL Authentics 300 ranks #45 of 100 boombox speakers by sound quality at $299.95.
What the Amazon Echo Dot Max does well: A compact Alexa smart speaker with a 2.5-inch woofer and dedicated tweeter, an excellent far-field microphone and a balanced midrange for clear voices. It supports AAC Bluetooth, which the JBL Authentics 300 lacks. The tradeoff: Engadget’s main complaint was that it is a real step down from the discontinued Amazon Echo (4th Gen) it effectively replaces at the same price: that older speaker paired a 3-inch woofer with dual 0.8-inch tweeters, against the Dot Max’s single 2.5-inch woofer and one tweeter, and frequencies felt smushed together without a clean bass-to-treble separation.
The JBL Authentics 300 is the battery-powered choice. Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). Its battery is rated for 8 hours, while the Amazon Echo Dot Max needs an outlet. It has an adjustable EQ, which the Amazon Echo Dot Max lacks. The catch: Narrow sounding, bass not as deep as others.
Buy the Amazon Echo Dot Max at $89.99 for a powered desktop speaker, or the JBL Authentics 300 at $299.95 for a boombox speaker instead.
