Basic question on the load capacity of tweeters

Hello, I would have a question of understanding quickly: And I wonder, how much power passively separate HTs actually get off. I mean this, theoretically, if an FS is given e.g. with 150W RMS and I also “feed” it with 150W, because at nem 200Hz Singal the TMT gets the full 150W off (impedance change sometimes excluded) and at 10kHz the HT the full power. But is that really so? Such an HT will need much less power and above all tolerate al So I’m starting from cheap 2-way systems… Why don’t I gril the HT when I turn it up? The impedance of an HT will usually be 4 ohms, so it shouldn’t be that way. Please explain to me… MfG, Diddy
