Short answer: the Tower Max for a wheeled 360-degree system, the Rockster Air 2 for battery life and off-axis consistency. The Max’s nine drivers and ULT1/ULT2 modes suit a living-room-to-backyard party, but it is AC-only. The Teufel claims a 58-hour battery and uses a horn-loaded compression tweeter for more even off-axis coverage, and at $499.99 it costs less.
This pits Sony’s Tower Max, a 360-degree consumer party speaker, against the Teufel Rockster Air 2, a performer-focused battery PA. The Tower Max offers nine drivers including three 11-inch woofers, 360-degree sound, 10-band EQ with Sound Field Optimization, wheels, and RCA/XLR/USB-C/mic I/O, though it is AC-only with no battery at all. 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 Max 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: It also runs on battery power at all, where the Tower Max is AC-only. At $499.99 it also costs less.
Buy the Sony ULT Tower Max at $1,198 for a large party speaker, or the Teufel Rockster Air 2 at $499.99 for a battery-powered PA speaker instead.
