Was a tough and tiring Friday. I want to listen some music (but I need to tweak some). Ok, fire up my iron and start to cook it right away.
Ok, basically I just add 0.47uF K40Y-9 capacitor on my high pass filter. Current configuration is a little bit too bright on the tweeter, so I need to lower the F3 of my high pass filter. So here it is…
The high pass is 2rd order, combination of Siemens PIO and K40Y-9. Also Sfernice resistor used there. The inductor is Alpha Core Foil Inductor. Bought it few years ago, not the price is getting high and higher!
