The ULT Tower 7 claims 30 hours with the lights off, spreads sound in 360 degrees, and has balanced XLR, RCA and mic inputs, LDAC and a 10-band EQ. It is IPX4.
Buy the Sony ULT Tower 7 at $649.99 if you want a party speaker. Buy the JBL Partybox 1000 at $1,099.95 if you want 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 $650: 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.

JBL Partybox 1000: $1,099.95 Amazon eBay
Pros: Handle and wheels are convenient. Right up there with the Partybox Ultimate, this was the previous speaker in that size. A better value than the Partybox Ultimate. Nice waterfall lightshow.
Cons: Very large and heavy. No battery. No app.
