A:Answer They are rated at 100 watts peak, but they are efficient enough at 89 db (at 1 watt at 1 meter) that you won't need that much to hit a high volume. Remember, you get a 3 db increase every time you double the power, so 92 db at 2 watts, 95 db at 4 watts, 98 db at 8 watts, 101 db at 16 watts, and so on.
