These sit in different size classes, so this is not a straight ranking comparison. The JBL Boombox 4 ranks #20 of 76 boombox speakers by sound quality at $429.95; the W-King T12 ranks #19 of 40 party speakers by sound quality at $379.04.
What the JBL Boombox 4 does well: Pretty insane output capability for the size. Watch for: Pretty overpriced for the category.
What the W-King T12 does well: A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. The tradeoff: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound.
Buy the JBL Boombox 4 at $429.95 if you want a boombox speaker. Buy the W-King T12 at $379.04 if you want a party speaker instead.
Water resistance is not close: the JBL Boombox 4 is rated at IP68 (extended submersion), well ahead of the W-King T12 at no water resistance.

Older models: the JBL Boombox 3 (rated 3.8/5), the JBL Boombox 2 (rated 3.5/5) and the JBL Boombox (rated 2.9/5).
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.

W-King T12: $379.04 Amazon AliExpress eBay
Pros: A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. Its claimed 25-hour battery and trolley-style form make it practical where high output matters more than compact size.
Cons: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound. It is a 15kg, 75cm-tall speaker with no water rating and no app; the physical tone controls are its only meaningful way to adjust the sound.
