These sit in different size classes, so this is not a straight ranking comparison. The JBL Boombox 4 ranks #20 of 113 boombox speakers by sound quality at $549.95; the W-King T12 ranks #22 of 53 party speakers by sound quality at $379.99.
The JBL Boombox 4 is the lighter, tougher choice. An extremely loud boombox for its size with fully waterproof, dustproof build, a long battery and a flexible app EQ. At 13.2 lbs (5.98 kg) it weighs much less than the W-King T12 at 33.1 lbs (15 kg). It is rated IP68, while the W-King T12 has no water resistance. It supports AAC Bluetooth, which the W-King T12 lacks. Watch for: Pretty overpriced for the category.
What the W-King T12 does well: A large wheeled karaoke party speaker with dual 8 inch woofers, bass and treble knobs, and a long battery for big outdoor events. It keeps a wired aux input, which the JBL Boombox 4 lacks. It has a microphone input for karaoke or announcements, which the JBL Boombox 4 lacks. The catch: 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 $549.95 if you want a boombox speaker. Buy the W-King T12 at $379.99 if you want a party speaker instead.
