I remember reading way back when i was really into in the home hi-fi world, that feeding distortion into some speakers harms them. Can I use a high-gain distortion preamp in front on my Henriksen Bud? Will it destroy the speakers?

If it is a pre-amp, why would it hurt the speakers? How else would you amplify the sound? Without speakers?

I think there are big differences between PA speakers (like the speaker in the Bud) and home audio HiFi speakers. But I'm curios, is it harmful to the HiFi speakers to listen to heavy metal?

Or put a resistor on the tweeter line to drop the signal going to it. Or a cap of the value you want for the frequency you want going to the tweeter.

sorry I don’t buy any of that ....
if if you could harm a tweeter by putting
distorted sounds into it , then how could
Mettalica go on tour or sell any CDs or downloads ?

distorted guitar into a tweeter does sound
fairly horrible tho !
(hence speaker emulation , low pass filters etc etc)

Maybe the original article you are remembering was advising against feeding a signal to a speaker that is distorted from high gain at the power amp stage? I’m having trouble wrapping my head around how a high gain pedal could damage the speakers just by virtue of the signal having a distorted sound. The overall signal level sent to the speaker will be determined by the power amp of the Bud. You could distort the hell out of the signal in the pedal, but keep the sound pressure level at literal whisper levels using the Bud’s volume controls and I’d wager the risk to the speaker would be nil.

I've been using a Tube Screamer for soloing with my Bud 6 (Channel 2, Bright Switch on, Tweeter off; Gain at 12, Volume at about 10:30) for living room rock band rehearsals with no ill effects for a while. The speaker is a high-power PA speaker. I don't think you'll have a problem at all. Just leave the tweeter off.

If the amp itself is clipping/distorting, there's a risk of blowing a speaker driver (see here for an explanation as to why), but a distortion pedal is not driving the amp's circuitry into clipping*. It's doing its own clipping of a very low level signal, and your amp is just making that clipped (and compressed) waveform loud. All that said, an OD pedal into an amp with a hi-fi frequency response usually sounds pretty bad.
* Within reason. If you dime all the knobs on a distortion pedal that has a lot of gain, you might push the amp into clipping, even if the amp is not cranked all the way up and thereby cook a driver. But as a practical matter, it takes a cranked amp to blow a speaker driver, unless there's a huge mismatch between the speaker's and amp's power handling capabilities.

The peaks get squashed and spread out, and the slopes on either side get fatter - but there’s little or no sharp cutoff. This is why “tube distortion” (especially output tube) is smoother in character and comes on gradually with little or no further increase in volume. It’s also why tube amps (and a few modern SS designs) clean up with lighter picking with the gain control(s) set at the sweet spot.
Low power SS amps pushed too hard blow far more speakers than amps that can put out more power than the speaker is rated to handle. When in doubt, more power is safer than less.

So the difference here is the original signal coming from the guitar pickups vs that very same signal first recorded and then replayed. Right?
What am I missing?
EDIT:
After reading what I posted, I realize it's not exactly accurate.
The difference is the original signal which is the output of a, say, pedal board, vs that signal first played through a guitar (amp and) speaker and then recorded.
So the signal obtained by mic'ing the guitar amp is then somehow a more tamed version of the original signal. I guess that's a possibility.

If the DSP includes amp & cab sims identical to the amp & cab used for the mic’ed recording, both should sound the same, break down into identical FFT plots, and have the same effect on the speaker.
