I can't believe I haven't found anyone explaining this anywhere on the internet.
Anyways, I want to take the output of any amplifier signal and convert it to sound through an 8 ohm speaker (lets say I bought at a flea market a long time ago with no specs) so that I can only hear sounds between about 61Hz and 20Khz (normal audio range).
The closest setup I've seen to this circuit are circuits involving the LM386 amplifier but they never explain how the component values are achieved.
Other resources state the horizontal capacitor and the speaker make up a high-pass filter and the capacitor and resistor in series make up a low-pass filter.
Can someone clarify this? and can someone tell me if the values shown are accurate?
