Short answer: the Sony ULT Tower 7 for price and app EQ, the Soundboks 4 for output and weatherproofing. The Tower 7 costs less at $548 and brings wheels, 360-degree seven-driver sound and 10-band EQ with a 30-hour claimed battery. The Soundboks 4 claims 126dB from dual 10-inch woofers, 40 hours on a removable battery, IP65 weatherproofing and XLR/instrument combo inputs.
This pits Sony’s Tower 7, a 360-degree consumer party speaker, against the Soundboks 4, 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 Soundboks 4 offers dual 10-inch woofers rated to 126dB max SPL, a removable 40-hour battery, IP65 weatherproofing, and XLR/instrument combo inputs.
Choose the Tower 7 for wheels for easier transport, immersive 360-degree party sound and a lower price: 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. At $548 it also costs less.
Choose the Soundboks 4 for higher peak output and full weatherproofing: Its claimed 40h battery beats the Tower 7’s 30h.
Buy the Sony ULT Tower 7 ($548) for a party speaker; the Soundboks 4 ($1,199) suits a battery-powered PA speaker instead.
