Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony ULT Tower 7 ranks #1 of 53 party speakers by sound quality at $649.99; the Sony ULT Tower Max ranks #1 of 12 large party speakers by sound quality at $1499.99.
The Tower 7 is the battery-powered sweet spot; the Tower Max is a full AC event speaker. Tower 7 offers a claimed 30-hour battery, 420W output, wheels, 360-degree sound and a seven-driver layout. Tower Max moves to three 11-inch woofers, 2,150W specified output and 56.3kg of AC-only hardware.
Choose the Tower 7 for mobile events: It is far easier to transport, can run without mains power and still provides XLR, RCA and USB-C connectivity.
Choose the Tower Max for the highest output and bass: AudioTribe measured 110.6dBC at about 6m outdoors from the Max. Its size and AC requirement only make sense when that extra scale is genuinely needed.
Buy the Sony ULT Tower 7 ($649.99) for a party speaker; the Sony ULT Tower Max ($1499.99) suits a large party speaker instead.

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 Max: $1,499.99 Amazon eBay
Pros: AudioTribe measured 110.6dBC at roughly 6m outdoors with Flat EQ and ULT1 enabled, 4.4dB above the JBL PartyBox Ultimate in the same setup. Its three 11-inch woofers held about 110dB from 40-100Hz; Sony also provides 10-band EQ, Sound Field Optimization, RCA and XLR inputs, USB-C, a mic input, and XLR output.
Cons: The same comparison found it 1.2dB behind the JBL in A-weighted loudness and weaker below 40Hz. At 56.3kg (124lb) and AC-only, this is a wheeled event speaker rather than a portable battery model.
