Short answer: the Soundboks 2 for peak output on a budget, the Sony ULT Tower 7 for features and app EQ. The Soundboks 2 claims 124dB from dual 10-inch woofers and a 40-hour removable battery at $449, beating the Tower 7’s 30-hour claim, but it is discontinued with no app EQ or TWS pairing. The Tower 7 counters with wheels, a 360-degree seven-driver layout and ULT1/ULT2 modes. The Soundboks 2 is discontinued; its replacement is the Soundboks 4.
This pits Sony’s Tower 7, a 360-degree consumer party speaker, against the Soundboks 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 Soundboks 2 offers dual 10-inch woofers rated to 124dB max SPL and a removable 40-hour battery, though it is a discontinued model without app EQ or TWS pairing.
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 Soundboks 2 for higher peak output at a lower price, discontinued caveats aside: Its claimed 40h battery beats the Tower 7’s 30h. At $449 it also costs less. It is discontinued, so check current stock and condition before buying.
Buy the Sony ULT Tower 7 at $548 if you want a party speaker. Buy the Soundboks 2 at $449 if you want 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 Soundboks 2 at no water resistance.
