Short answer: the Zealot ZE41. It ranks #14 of 73 boombox speakers by sound quality at $289.90; the JBL Authentics 300 ranks #30 and costs $299.95, which makes this an easy call rather than a real tradeoff.
What the Zealot ZE41 offers: The absolute best value for the bass performance, play time and max volume in the boombox class. Watch for: The heaviest and biggest boombox speaker around. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.
What the JBL Authentics 300 offers: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). Retro seventies design with leather and Quadrex grille. 100-watt amp, carries well with leather-trimmed handle. Rechargeable battery rated ~8 hours. Watch for: Narrow sounding, bass not as deep as others. Peaky upper mids. No TWS. No IP rating. Not as loud as others. Not much battery life.
Buy the Zealot ZE41. It ranks higher for sound quality than the JBL Authentics 300 and costs less, so the other one has nothing left to offer.
If water resistance matters to you, the Zealot ZE41 at IPX5 (water jets) holds up far better than the JBL Authentics 300 at no water resistance.
