Short answer: the Sony ULT Tower 7 for battery operation and current connections. It offers 420W, a claimed 30-hour battery, wheels, 360-degree sound, 10-band EQ and RCA/XLR/USB-C, while the Tower 10 is an older 63.9 lbs (29 kg) AC-powered design. Existing review notes report the Tower 10’s bass dropping substantially at high volume, so verify that tradeoff before choosing it for a loud event.
The Tower 7 updates Sony’s large battery-powered party-speaker formula. It offers 420W, a claimed 30-hour battery, wheels, 360-degree sound, 10-band EQ and RCA/XLR/USB-C. The Tower 10 is the older generation with a 63.9 lbs (29 kg) AC-powered design.
Choose the Tower 7 for battery operation and current connectivity: It can run away from mains power, carries its own wheels, and has the more versatile source-input selection.
Choose the Tower 10 only for its specific older-generation strengths: Existing review notes report bass dropping substantially at high volume, so verify that tradeoff against the newer Tower 7 before choosing it for a loud event.
