Hello
Built my first crossover or so I thought. I could use some help I have it all wired up up but my speakers are still receiving the full audio band signal. This should be a third order crossover. This is the high pass section. It’s a 4 ohm crossover for 1khz
It's a little tricky to tell some parts of it just looking at the picture. If you can look at the board and convert it back into a fresh schematic, this may help as a cross check? It's also a good thing to check continuity and isolation in various positions.
One can clearly see it is a T network consisting of 2 capacitors in series and a shunting inductor. A schematic is unnecessary, maybe values of components may be more helpful.
I am not sure if this helps but essentially I have the following
Positive to black cap running to red cap positive out of red cap to tweeter the inductor is in the middle of the 2 caps
Ground negative running from bottom of inductor t back to amplifier and to tweeter
Positive to black cap running to red cap positive out of red cap to tweeter the inductor is in the middle of the 2 caps
Ground negative running from bottom of inductor t back to amplifier and to tweeter
Attachments
Are there two wires attached to the inductor to negative? Hopefully one of them isn't a positive wire.
I ran the simulation earlier, but didn't know the impedance of your tweeter. You're crossing to the tweeter around 670hz. Is that your goal? What tweeter are you using?
That’s the simulation? That explains a lot. I am looking for a 3rd order Butterworth crossover at 1khz. This looks like the values I am using is not giving the correct crossover point at all. Are you able to assist by chance?
Change the shunt inductor to 500uh and you are there. What makes you think you are getting full voltage in your case?
