Short answer: the Sony ULT Tower 7. It ranks #1 of 39 party speakers by sound quality at $648; the Soundboks Mix ranks #24 and costs $799, so there is not much of a tradeoff to weigh.
What the Sony ULT Tower 7 offers: A compelling large-party value at $649.99: 420W output, an IPX4-rated 30-hour battery, 360-degree sound, wheels and four carry handles at 22.8kg. The full review praises its punchy, clean ULT1 bass, ULT2’s higher-output mode, simplified controls and unusually complete I/O: USB-C, USB-A, RCA, balanced XLR and mic input. Watch for: 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. IPX4 is splash resistance rather than full weatherproofing; the 30-hour claim requires lights off.
What the Soundboks Mix offers: 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. Watch for: 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 4, and no microphone input for karaoke like the Pro Panel models.
Buy the Sony ULT Tower 7. It ranks higher for sound quality than the Soundboks Mix and costs less, so the other one has nothing left to offer.
