What wattage can the 16ohm cab take? How many speakers is it? Is it two 16ohm speakers which actually means an 8ohm load, or is it a 1 speaker cab with 16ohms? And why is this in the bar and not in the backline section? Hahaha
You can find the watts it sends (and other stuff) in the instruction manual here:
