I have a 3" mid-range driver rated 20W peak and 10W RMS. How much power could it take for a very spiky waveform like a square wave through a (1st-order) highpass filter?
Generally mid units can take phenominal peak power inputs,
as long as the transient is within excursion limitations, and
the average thermal power is within thermal limits.
(The high power transient must be short compared to the
drivers thermal time constant, so its not heated too much)
Simply put a spiky waveform has peak to average ratio,
increasing this ratio barely affects the average power.
So for a 10dB ratio we are talking a 100W amplifier, for
a 20dB ratio a 1000w amplifier, its already getting silly.
So basically you do not need to worry about transient power handling.
