Short answer: the Sony ULT Tower 7 for a larger event, the SRS-XP500 for a less demanding setup. The Tower 7 brings 420W, a claimed 30-hour battery, 360-degree seven-driver sound, wheels and a full RCA/XLR/USB-C input section. The XP500 is the older, smaller approach that fits better where the Tower 7’s extra scale is unnecessary. The Sony SRS-XP500 is discontinued; its replacement is the Sony SRS-XV500.
These speakers sit at different scales. The Tower 7 offers 420W, a claimed 30-hour battery, 360-degree seven-driver sound, wheels and a full RCA/XLR/USB-C input section. The XP500 is the older, smaller Sony party-speaker approach.
Choose the Tower 7 for a larger event: Its higher claimed output, rear tweeters and better wired connectivity make it more suitable for a wide room, DJ source or extended battery-powered party.
Choose the XP500 for a less demanding setup: Its smaller size can be the better fit where the Tower 7’s extra scale is unnecessary.
Buy the Sony ULT Tower 7. It is rated higher for sound quality and still sold new, while the Sony SRS-XP500 is discontinued.
There is a real gap in water resistance: the Sony ULT Tower 7 at IPX4 (splashing) against the Sony SRS-XP500, which has no water resistance.
