Default Guitar speakers emulation

Can ordinary hi-fi speakers reproduce guitar speaker sounds (the "scratching paper" sound) ? Can they reproduce any waveform the microphone has captured?

If yes then surely we could make an electronic circuit to go inside guitar amps and allow them to use ordinary, mass produced, cheap PA speakers rather than expensive, low volume, specially made guitar speakers?

You could have just googled this before posting. There are many commercial and DIY "cabinet simulator" circuits out there for guitar.

Thanks. Somehow I did not think to search the internet, or the word "cabinet" or "simulation" :-)

I have played guitar for 35 years and always made my own cabinets.
I only used guitar speakers once and couldnt tell the difference.

If your trying to get that valve sound that guitar players love then look up "soft limiter" and that will get you somewhere close.

"expensive, low volume"

I'm sorry, but since when did a 50 watt speaker at 108dB efficiency ever fall into the low volume section?

Yes, you can play guiatr through PA speakers, but I noticed a difference between my hifi speakers and my amp. Amp uses an 8" driver, hifi is a pair of 5"s, with 8"s for bass.

That's not the reason some guitar cabs are even extremely expensive. Guitar cabs are not speakers in the strictest sense of the word, they're instruments. The same guitar sounds very different on different speakers and with different effects. The sound of a guitar is combination of all these things and not the just the guitar itself.

You can get extremely cheap guitar cabs too because basically they're just a pair (or 2 pairs) of full-range drivers with high-Q, high sensitivity and a frequency linearity as jagged as the Badlands, combined with an underpowered amplifier.

True, at least sometimes.
My Piggy amp, cost next to nothing, sounded better than my friends HUGE, expensive Peavey stack.
