I wasn't quite clear enough there. It is the yellowish rough coating. Not the red coating.

That yellowish coating is in fact the solid copper wire that make up the coil. The other leads are silver because the have been coated in solder. Go ahead and solder together as required!

You can always clean it up with a little steel wool or sand paper.

I am building the X-LS speakers.  This my very first speaker build.  I have almost finished the crossovers.   What is the recommended procedure for test crossovers before burying them in the enclosure?

I use pigtails with alligator clips. I use a total of six pairs (positive & negative). Two of the pairs are cheap speaker wire connected to the amp at one end however you want. The other end has alligator clips and connects to the input wires of the crossovers. The other 4 pairs of pigtails have alligator clips on both ends. They connect the individual drivers to their respective circuits on the crossover boards.



Connect everything up, making sure nothing is touching something it shouldn't, then turn the amp on and play something. Don't get crazy trying to get the drivers to play loud, you might damage something. Listen closely and make sure the drivers are playing properly.

Thanks.  That's not to complicated.  I was thinking I would have to buy a microphone and use some software like REW or ARTA.

Not for testing the crossover network. That would be for setting up the room once they are built.

I'm not sure why your wiring is underneath the board. That makes it a little hard to confirm everything. If you would have kept the wiring up top then I could look at the pictures of what you've done and confirm all is fine or not.

Well, I thought I would pass the wires underneath then back up to provide some form of strain relief.  In hindsight, I now see that once the crossover is installed and the enclosure sealed there never is any strain on the wire connections.

I have not solder any of the conncetions yet.  Let me see what I can do to put the wire back on top.

Looks correct.  :thumb:

See some of the examples at the first of this thread. Wiring is connected in such a way as to allow the supplied heat shrink to be used on the high purity OFC wire. Sealing the ends will keep the Copper from oxidizing over time and keep it all sounding good.

I really appreciate the help on my first build.  I order a second kit of the X-LS.  Taking Danny's recommendations from the above post.  Here is the next crossovers build that i was able hide the high purity OFC wire in heatshrink.
