ZD3C Center questions

[ROS.SNK]

Hi. Where can I find the Zaph ZD3C center BOM? The only thing that I can find on his website is a picture of crossover and I would like to know the exact parts needed for it.

There is no BOM that I can find.

The crossover design isn't published because they want you to buy the kit from Madisound.

Not sure what the confusion is here. The following link is the first thing listed under the "ZD3C Center Channel Option" section of the ZDT3.5 site.

Rather than giving you specific part numbers, he specifies the EXACT paramaters for each part including resistance of the inductors so you can build using your favorite parts and still come up with an "as designed" XO. If you are having a hard time finding the specific parts make sure you are searching the Madisound site as most of his parts come from there.

Oh, woops. I guess the crossovers are published. My mistake.

Zaph typically doesn't post the exact crossover parts.

OP asked for a BOM, calling out part numbers and brands, like the one in the ZDT3.5 showcase article. There is none.

OP is in Poland.

I think the CCs BOM is the same as the Tower, less some of the Woofer XO parts.

Ok. So I dont need to buy the red resistors showed on the crossover picture ( like r2, r9, r17), but why on the list next to it, some parts are written in red colour:
R4 - 1 ohm
R6 - 1 ohm
L16- 1,5 mH

Should i buy parts R4,R6,L16 with values like that?

No you don't need to buy the resistors shown in red on the picture. That is just the resistance value of the inductors.

Parts R4, R6, and L16 are in red font because those are parts that changed values in comparison to the tower crossovers.

Ok. The last thing that I dont know is:
L1 0,08MH and
L16 1,5MH
How many ohms they should have, because there is many different to choose?

[djg]

L1, L8, and L16 have red resistor symbols next to them. These are not actual resistors, but tell you the correct resistance of the inductors. The answer to your question is that L1 should be .1 ohm, L8 .49 ohm, and L16 .38 ohm. This is looking at the crossover diagram for the center channel ZDT3 CC on zaph's website.
