These are not really the same size class, and that is the honest framing here. The JBL Partybox 1000 ranks #3 of 12 large party speakers by sound quality at $1,099.95; the Sony ULT Tower 5 ranks #5 of 40 party speakers by sound quality at $448.
Why pick the JBL Partybox 1000: Handle and wheels are convenient. The catch: Very large and heavy.
Why pick the Sony ULT Tower 5: At $448, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. The tradeoff: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
Buy the JBL Partybox 1000 ($1,099.95) for a large party speaker; the Sony ULT Tower 5 ($448) suits a party speaker instead.
There is a real gap in water resistance: the Sony ULT Tower 5 at IPX4 (splashing) against the JBL Partybox 1000, which has no water resistance.

The Two Speakers In Full
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.

Sony ULT Tower 5: $448.00 Amazon eBay
Pros: At $448, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. AudioTribe’s first impressions praise its deeper bass and clearer sound than the JBL PartyBox Club 120; it also has USB-C and USB-A, RCA, balanced XLR and mic inputs for DJ and karaoke use.
Cons: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance. Its single-woofer, two-tweeter layout lacks the Tower 7’s 360-degree rear-driver array, and the reviewer describes the sound assessment as first impressions rather than a controlled measurement comparison.
