Short answer: the Sony ULT Tower 7. It ranks #1 of 51 party speakers by sound quality, rated 4.7/5, at $548. The W-King T12 ranks #21, rated 3.8/5, at $379.99, $168.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Sony ULT Tower 7 is the better-sounding, tougher pick. A big, loud party speaker on wheels with punchy bass, a 30 hour battery, 360 degree sound and inputs for mics and instruments. It is rated IPX4, while the W-King T12 has no water resistance. It supports LDAC Bluetooth, which the W-King T12 lacks. It links with other speakers (Auracast), which the W-King T12 cannot. The catch: The reviewer notes that Auracast pairing is not backward-compatible with Sony’s older Party Connect speakers, and the hard-plastic corners lack protective rubber bumpers.
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 noticeably less than the Sony ULT Tower 7 at 50.3 lbs (22.8 kg). 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 Sony ULT Tower 7. It is rated higher for sound quality, and the $168.01 saving on the W-King T12 is not enough to make up the difference.
