Short answer: the Teufel Rockster Air 2 for battery life and off-axis coverage, the Sony ULT Tower 7 for 360-degree sound. The Teufel claims 58 hours and uses a horn-loaded compression tweeter for more even off-axis coverage than a typical front-firing party speaker, and it costs less at $499.99. The Tower 7’s claimed 30-hour battery is shorter, but its wheels and 360-degree seven-driver layout suit a living-room-to-backyard party.
This pits Sony’s Tower 7, a 360-degree consumer party speaker, against the Teufel Rockster Air 2, a performer-focused battery PA. The Tower 7 offers seven drivers for 360-degree sound, a claimed 30-hour battery, wheels, IPX4 splash resistance, 10-band EQ and a full RCA/XLR/USB-C/mic input section. The Teufel Rockster Air 2 offers a horn-loaded compression tweeter for more even off-axis coverage than a typical front-firing party speaker, a 58-hour claimed battery, and XLR mic/instrument inputs.
Choose the Tower 7 for wheels for easier transport and immersive 360-degree party sound: Its wheels also make it easier to roll between rooms or events. Its 360-degree drivers and ULT1/ULT2/EQ modes suit a living-room-to-backyard party speaker better than a performer-focused PA cabinet.
Choose the Teufel Rockster Air 2 for the longest claimed battery in the class and wider off-axis coverage: Its claimed 58h battery beats the Tower 7’s 30h. At $499.99 it also costs less.
Buy the Sony ULT Tower 7 ($548) for a party speaker; the Teufel Rockster Air 2 ($499.99) suits a battery-powered PA speaker instead.
Water resistance is not close: the Sony ULT Tower 7 is rated at IPX4 (splashing), well ahead of the Teufel Rockster Air 2 at no water resistance.
