Sony ULT TOWER 9AC vs Sony ULT FIELD 3

Despite belonging to the same ULT POWER SOUND line, the Sony ULT FIELD 3 and Sony ULT TOWER 9AC are made for completely different scenarios. Your needs will determine which makes more sense. The ULT FIELD 3 is much smaller and battery-powered for portable adventures and toting around with you. While it includes inputs for a mic and guitar, it's not loud enough to cut through a crowd. In contrast, the ULT TOWER 9AC needs to plug into a power source, and while it has wheels, it's comparatively very large and heavy. You get more low-end due to its size, and it reaches high volumes, plus the connectivity still includes mic and guitar inputs.
