Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony ULT Tower 9 ranks #10 of 13 large party speakers by sound quality at $898; the W-King T12 ranks #22 of 53 party speakers by sound quality at $379.99.
The case for the Sony ULT Tower 9: A battery powered party tower with good sound, a long battery, karaoke inputs, and a detailed app EQ. It supports LDAC Bluetooth, which the W-King T12 lacks. It links with other speakers (Auracast up to 100 speakers), which the W-King T12 cannot. The catch: Not as deep of bass and loses more bass at high volume even compared to the lower end Partybox speakers.
The W-King T12 is the lighter option. A large wheeled karaoke party speaker with dual 8 inch woofers, bass and treble knobs, and a long battery for big outdoor events. At 33.1 lbs (15 kg) it weighs much less than the Sony ULT Tower 9 at 65.3 lbs (29.6 kg). 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 Sony ULT Tower 9 at $898 for a large party speaker, or the W-King T12 at $379.99 for a party speaker instead.
