Short answer: the Soundboks Mix for better sound quality, the W-King T9 Pro for the lower price. The Soundboks Mix ranks #28 of 46 party speakers at $799. The W-King T9 Pro ranks #31 at $171.49, $627.51 cheaper.
What the Soundboks Mix gets right: IP65 dust/water resistance and 65W USB-C fast charging for its swappable battery, plus TeamUp linking with up to 5 other SKAA speakers. The catch: only 72W from a single 10-inch woofer, and it can sound bright in the treble.
On the W-King T9 Pro side: 250W peak power across dual 6.5-inch woofers for more raw output. The tradeoff: sounds warm and somewhat gritty, without the polish of pricier options.
Buy the Soundboks Mix if sound quality matters more than the price. Buy the W-King T9 Pro if the price matters more than sound quality.
