I am using a 35wpc amplifier with the speakers which have requirement of >15w and program power rating of 50W.
Now, I have read a lot about the head room and that one should use double the power for the amp. So I guess in my case 100W instead of 35W.
Well, I wondered if I added HPF 100Hz 24dB/octave at the line level and sent this signal to the amp, would this cause speakers to draw less power?
I mean, will this help the amp to get into clipping at higher volume then in case when the full signal is sent? Or amp clipping is totally independent of frequency?
I also found this article: Q. Why do my mixes clip when I apply a high-pass filter? | but not sure if this applies to line level HPF or this is something which is relevant only for mixing.

Dynamic HEadroom is not related to the program material
There are musical genres such as hip-hop or electronic music where bass is more dominant but the characteristic of an amplifier should stand on its own
😱
It's well know that an amplifier that clips is prone to produce extra harmonics and those would kill a tweeter's bobbin.
Likely you'd need a 100 W amplifier that'll play most of the time > 1W but for music peaks ( like...+20 dB) those are needed

Well less bass should cause less power rail sagging. Which should allow more power at high frequencies but I suspect that the gain would be small. The quality of the PSU would determine the amount gained. Unless of course the PSU is very much under rated.
Yes, doing so should increase the headroom available for frequencies above 100Hz. Power not consumed for the bass will be available elsewhere. As most know, bass program content typically makes the greatest demand on system headroom. This power spectrum of music is heavily biased toward the bass. This the nature of most music. This is also why good amplified subwoofers often feature very high power amplifiers.

Thank you for all the comments.
It seems the amp will have more power for 100Hz-20kHz range when I cut everything under 100Hz @24dB/octave.
What confuses me is following. Let's say there is a 15db transient peak in 3000Hz. So a tweeter which was playing at lets say 88dB at 1m needs to jump to 103dB.
Let's also assume tweeter is rated 88dB @1W. For this jump to happen, amplifier needs to send 32W to the tweeter.
How can tweeter even handle 32W, wouldn't this be too much for the tiny coil?

Transient peaks ( which in most music theses days don't exist) are so fast they don't send enough power to burnout a voice coil. It may cause over excursion but shouldn't damage anything.
Right, but there are still some records which have them, though.
Ok, I think I get it now.
Are these assumptions ok?
The transients are in general fast enough not to damage the speaker, but can still bring the amp to clip.
As this clip is so short, can one also say it wouldn't break the speaker?
On the other hand if one turns the volume to the max and amplifier starts clipping due to the majority of signal is making him clip then this "type" of clipping is about the kill the driver.
