adjust normal speaker to use as guitar speaker? Answered

Hi,

As you know normal speakers (Hi-Fi, cassette players,...) and electric guitar amplifier speakers are different. Apparently guitar ones work in 75Hz to 5KHz frequency range.  I want to make a normal speaker to sound as much as possible, like a guitar speaker. after searching on the internet I found that with band-pass or band-stop passive filter I can achieve that.

Anyone have any idea how can I do this and if this is going to work or make any difference?
Do you have other suggestions (besides buying guitar amp or speakers ) ?

Thanks  for your help

Well for one you will need an amplifier of some sort, whether it's built in to the speakers or inline between the guitar and speaker. You'll need to have this sorted before worrying about frequency range.

I forgot to mention that I have an amplifier . It's based on TDA2005 chip and can produce 20W . Input impedance of this amplifier is about 100k ohms, so I had to make a buffer ( http://www.muzique.com/schem/eagle.htm ) , which drastically improved my guitar's sound.
I have tried High-pass filter using a capacitor and resistor, I don't know why but it seems that resistor does nothing, only capacitor is filtering low frequency. Low-pass filter was worse, it just reduced volume !
