Help how to use or is there any limiting resistors required to use to 150 watts tweeter to 400 watts amplifier
Is the amplifer 400 watts a channel or 400 watts into 2 or 4 channels?
Is the 150 watt rating of the speaker maximum peak or continuous run power?
Either keep the volume bellow 25% or yes you can attenuate the power on the speaker side but the result will be the same lose of volume...

amplifier is 2 channels 400 watts per channel
somebody donate amplifier in our church, but we have only 2 200watts speakers and 2 150 watts tweeters, i have to use that things to avoid buy another, so if you help me to make it remedy, i will appreciate it very much and i know God will bless you the way you help us, cause our tweeter is always blow, speakers are not problem cause i already control the sound to the volume

It's really impractical to attenuate a 400 watt amplifier with simple resistors on the output side, not only do you mess up the sound but it's you need heavy duty resistors best to do what I suggest and simply not turn up the volume past the 20-25% range...
But, if you must the easiest way is with an L-Pad... Pay close attention to the required power rating of the resistors, you are not going to be using small resistors but it will instead require some 100 & 200 watt power resistors to be safe... This will drop the maximum output to about 141 Watts to that speaker... Do the same for the other speaker...
I just 'assumed' 8Ω speakers if you have a 4Ω or 16Ωor whatever you will need to redo the math...
Also you are not going to find, 3.23 Ohm and 11.79 ohm resistors so you need to go up to the next common value... You will probably find a 4Ω @ 200 watt and a 12Ω @ 100 watt...

Did you place a capacitor in series with the tweeters or you directly connect the tweeter on speaker wire?
Purpose of capacitor in series was to allow only high frequency to pass and drive the tweeter. Without the capacitor , Low frequency or bass sound will drive directly thin voice coil of tweeter and be damage.

Rleo6965, there is capacitor already, what i need is to limit the power going to tweeter, to secure it
