Short answer: the Sony ULT Tower 5 for everyday party use, the Audiocase S10 for peak output. The Sony’s 9-inch woofer, ULT1/ULT2 modes, 10-band EQ and RCA/XLR/USB-C inputs suit a living-room-to-backyard speaker, and at $348 it costs less. The S10 hits a claimed 125dB and runs 30 hours on a removable battery against the Sony’s 20, but it is discontinued, so check current stock and condition.
This pits Sony’s Tower 5, a compact consumer party speaker, against the Audiocase S10, a performer-focused battery PA. The Tower 5 offers a 9-inch woofer with dual tweeters, a removable 20-hour battery, IPX4 splash resistance, 10-band EQ with ULT1/ULT2 modes, and RCA/XLR/USB-C inputs for DJ and karaoke use. The Audiocase S10 offers dual 10-inch woofers rated among the loudest in the category at 125dB max SPL, a removable 30-hour battery and XLR/instrument inputs, though it is now discontinued.
Choose the Tower 5 for big-room output and app EQ modes and a lower price: Its ULT1/ULT2/EQ modes and compact footprint suit a living-room-to-backyard party speaker better than a performer-focused PA cabinet. At $348 it also costs less.
Choose the Audiocase S10 for higher peak output, discontinued caveats aside: Its claimed 30h battery beats the Tower 5’s 20h. It is discontinued, so check current stock and condition before buying.
Buy the Sony ULT Tower 5 at $348 if you want a party speaker. Buy the Audiocase S10 at $892 if you want a battery-powered PA speaker instead.
There is a real gap in water resistance: the Sony ULT Tower 5 at IPX4 (splashing) against the Audiocase S10, which has no water resistance.
