These sit in different size classes, so this is not a straight ranking comparison. The JBL Partybox Encore 2 ranks #4 of 113 boombox speakers by sound quality at $330; the W-King T12 ranks #22 of 53 party speakers by sound quality at $379.99.
The JBL Partybox Encore 2 is the lighter, tougher pick. A compact karaoke party speaker with two wireless mics, better balanced sound than the original and a long battery. At 14.1 lbs (6.4 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. The catch: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
The W-King T12 is the longer-running option. 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 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 2 ($330) for a boombox speaker; the W-King T12 ($379.99) suits a party speaker instead.
