Short answer: the JBL PartyBox 130 is the more practical wheeled party speaker, while the Sony ULT Tower 9 makes sense only for a buyer who prefers its larger tower format. JBL is 7 of 44, and Sony is 10 of 13.
The PartyBox 130 gives you wheels and a handle, but its sound is boomier and less clear than the PartyBox 120. The ULT Tower 9 is slightly better sounding than the Tower 10, yet it does not reach as deep in the bass and loses more bass at high volume than even lower-end PartyBox models.
Buy the JBL PartyBox 130 if you want a more manageable party speaker and value its transport-friendly design.
Buy the Sony ULT Tower 9 if the tower form factor is the priority and you can accept its bass limitations at higher volume.
Battery life favors the Sony ULT Tower 9: rated for 25 hours against 15 hours for the JBL Partybox 130.
There is a real gap in water resistance: the JBL Partybox 130 at IPX4 (splashing) against the Sony ULT Tower 9, which has no water resistance.

The Two Speakers In Full
JBL Partybox 130: $449.95 Amazon eBay
Pros: A relatively manageable 11.3kg PartyBox with removable battery, foldable handle, light show, USB audio and modern JBL connectivity. Independent reviews describe it as unusually balanced and powerful for its format, while owner feedback praises clear voices and deep bass.
Cons: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons. The smaller battery and stripped-back controls/features make it a questionable upgrade when the 120 is similarly priced. JBL’s wired daisy chain only works with other JBL speakers.

Sony ULT Tower 9: $898.00 Amazon eBay
Older model: the Sony SRS-XV900 (ranked lower, rated 3.7/5).
Pros: Slightly better sounding than the ULT Tower 10
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. Not quite as loud as the ULT Tower 10
