Pioneer FS52 crossover - Modification

C1 - 1.8uf
C2 - 15 uf
C2 - 150uf
L1 - 0.39mh ( air core)
L2 - iron core (didn't measure)
R1 1.8Ohms
R2 2.2 Ohms
R3 3.9 Ohms
I am trying to replace the capacitors and resistors with Audio grade components

Hi Ranjith

I was able to measure the solid core inductor. My meter is showing 0.7mH. I am currently trying to draw a schematic of this crossover. When I get it done, I will share here.

If I did this correctly, here is the diagram for the SP-FS52 crossover design. I measured the 0.7mH inductor but was unable to properly measure the inductor for the tweeter. I assume the value is correct as Ranjith stated in a previous post.

Not sure if I got this right, hopefully someone here can confirm the diagram below is accurate.

Thanks

Here is a quick drawing of the Pioneer SP-FS52 crossover circuit board highlighting all the components (from both sides) and their solder points. Hope this helps.
