These are not really the same size class, and that is the honest framing here. The Sony ULT Tower 7 ranks #1 of 53 party speakers by sound quality at $649.99; the Sony ULT Tower 10 ranks #10 of 12 large party speakers by sound quality at $898.
The Tower 7 updates Sony’s large battery-powered party-speaker formula. It offers 420W, a claimed 30-hour battery, wheels, 360-degree sound, 10-band EQ and RCA/XLR/USB-C. The Tower 10 is the older generation with a 29kg AC-powered design.
Choose the Tower 7 for battery operation and current connectivity: It can run away from mains power, carries its own wheels, and has the more versatile source-input selection.
Choose the Tower 10 only for its specific older-generation strengths: Existing review notes report bass dropping substantially at high volume, so verify that tradeoff against the newer Tower 7 before choosing it for a loud event.
Buy the Sony ULT Tower 7 at $649.99 for a party speaker, or the Sony ULT Tower 10 at $898 for a large party speaker instead.
If sound quality matters at all to you, skip the Sony ULT Tower 10. It ranks near the bottom of the 12 large party speakers, so look higher up the list instead.
Water resistance is not close: the Sony ULT Tower 7 is rated at IPX4 (splashing), well ahead of the Sony ULT Tower 10 at no water resistance.

The Two Speakers In Full
Sony ULT Tower 7: $649.99 Amazon eBay
Pros: 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.
Cons: 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.

Sony ULT Tower 10: $898.00 Amazon eBay
Pros: Louder than the Partybox Ultimate. Includes a wireless microphone.
Cons: Not as deep of bass and loses more bass at high volume even compared to the lower end Partybox speakers. Bass drops off a lot at higher volumes.
