ok.. finally getting a free moment of spare time to fire up the iron..
I have essentially removed:
and replaced those with two 'female' ended leads each... (so I can stick a resistor or cap between each one and test out different values)
the only difference is that I have put a pot for R5/R6.. instead of two female leads each... since they share a ground...(basically there is only 3 female leads..with a trim pot used same way I am doing the resistors and caps, but I can easily replace with two separate static resistor values as well..)
this allows me to try and understand all this.. as well as play and get feedback in real time to understand how all this is 'related'..
I want to the highs to be 'crisp'...but not allow any static, hiss or pops through.....
and get as much clean, clear bass as well..
I know these are just hobby speakers so Im trying to be realistic as well..
So from the comments/reading.. the 100 ohm resistor in R8 is basically doing 'nothing'.. (barely having a low pass filter).. but if I jack that up.. its get 'muffled' not to be confused with 'muted'..
R8 = 5-10K
R18 = 10nF
R21 = 1uF
sound a bit better?
and now.. because that R21 cap is >= 1uF.. I should be using a polarized cap? (and this will also help on cutting out noise?)
