Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox Encore Essential 2 ranks #6 of 113 boombox speakers by sound quality at $249.95; the W-King T12 ranks #22 of 53 party speakers by sound quality at $379.99.
The JBL Partybox Encore Essential 2 is the lighter, tougher pick. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. At 13.7 lbs (6.2 kg) it weighs much less than the W-King T12 at 33.1 lbs (15 kg). It is rated IPX4, while the W-King T12 has no water resistance. It links with other speakers (Auracast), which the W-King T12 cannot. Watch for: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
The W-King T12 is the longer-running choice. A large wheeled karaoke party speaker with dual 8 inch woofers, bass and treble knobs, and a long battery for big outdoor events. It is rated for 25 hours of battery against 15 for the JBL Partybox Encore Essential 2. 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 Partybox Encore Essential 2 ($249.95) for a boombox speaker; the W-King T12 ($379.99) suits a party speaker instead.
