Dont be so hung up on the wattage if its a image tweeter 50 watts would be more than enough. its how you tune and blend everything in. I used to think like you, power, power, power. Power means nothing if you don't tune everything right. i think you can set your frequency at 10k for these and you will be extremely happy.
let me know i only have 2 left
these are brand new sets from CDT audio , never used, never installed
