#12 Zealot PT21: $216.73 Aliexpress
Pros: Dual 166mm woofers and 200W output in a lighter, more compact body than the ZE41, with a bundled wireless microphone and echo effect built in for karaoke. Quite deep bass for the price, even deeper than the JBL Boombox 4 in direct comparisons.
Cons: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
How it compares: Just above it: Electro-Voice Everse 8 - $582 more. Just below it: Bose S1 Pro - $482 more.
