Short answer: the Soundboks Mix for durability and linking, the W-King T9 Pro for raw output on a budget. The Mix is IP65 rated with 65W USB-C fast charging and TeamUp linking to five other SKAA speakers, but it manages only 72W from a single 10-inch woofer and can sound bright in the treble. The W-King puts 250W peak across dual 6.5-inch woofers, though it sounds warm and somewhat gritty.
Buy the Soundboks Mix when sound quality outweighs the price for you, and the W-King T9 Pro when the price outweighs sound quality instead.
Battery life favors the Soundboks Mix: rated for 40 hours against 12 hours for the W-King T9 Pro.
If water resistance matters to you, the Soundboks Mix at IP65 (water jets) holds up far better than the W-King T9 Pro at no water resistance.

The Two Speakers In Full
Soundboks Mix: $799 Soundboks Amazon eBay
Pros: USB-C fast charging (65W) for the swappable battery, up to 40 hours of battery life at mid-volume, IP65 dust/water resistance, and TeamUp linking with up to 5 other SKAA-equipped Soundboks speakers. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage.
Cons: Doesn’t have as deep of bass as higher-ranked speakers, and can sound somewhat bright in the treble. Only 72W of output and a single 10-inch woofer, less powerful than the Soundboks Go or Soundboks 4, and no microphone input for karaoke like the Pro Panel models.

W-King T9 Pro: $171.49 Aliexpress eBay
Pros: A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. The swappable battery is especially useful for long events, and its strong output gives it much more headroom than compact Bluetooth speakers.
Cons: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed. Its claimed output figures should not be mistaken for neutral sound quality, and a large cabinet with no stated water rating is a poor fit for wet outdoor use.
