Short answer: the Sony ULT Tower 7 for coverage, endurance and wired sources. Its 420W output, claimed 30-hour battery, rear tweeters, 10-band EQ and RCA/XLR/USB-C/microphone set are meaningful advantages for larger parties. Pick the XP700 only when its legacy form factor fits better, since the Tower 7 is designed to replace the old high-output Sony party-speaker role.
