Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The W-King T12 ranks #22 of 53 party speakers by sound quality at $379.99; the Turtlebox Grande ranks #81 of 113 boombox speakers by sound quality at $730.
The case for the W-King T12: A large wheeled karaoke party speaker with dual 8 inch woofers, bass and treble knobs, and a long battery for big outdoor events. It has an adjustable EQ, which the Turtlebox Grande lacks. 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.
The Turtlebox Grande is the lighter, tougher pick. A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. At 18.8 lbs (8.53 kg) it weighs much less than the W-King T12 at 33.1 lbs (15 kg). It is rated IP67, while the W-King T12 has no water resistance. It links with other speakers (Turtlebox Party Mode), which the W-King T12 cannot. The catch: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
Buy the W-King T12 at $379.99 if you want a party speaker. Buy the Turtlebox Grande at $730 if you want a boombox speaker instead.
