12.5 ohms will likely be okay on it. It'll have marginally more output than the schematic for the tweeter range, but it should be okay.
But- this should work for you:
12 Ohm 10W Resistor Wire Wound 5% Tolerance 016-12

OK, I saw those but I have never used a resistor that's not "Non-Inductive" for crossover networks.
Last night I completed the first Silver AL's "UE".
I do have to say the results are promising.
I already have better imaging and the tweeter sounds less congested.
I ended up paralleling a few caps to get the values I needed and I custom unwound inductors from parts I had on hand.
My .40mH's ended up being .395mH but since they are both the same I don't expect there to be any major issues.
I will post pics after I have the second one completed and I have a good listen.

Good! I built the karmas for my brother and he loves them! I will be building the silver Al crosses to try out. My karmas have a bit, just a bit of sibilance but it is not a deal breaker by any means. I used lol Dayton caps but that will be changing as well.
I used Dayton Poly's all around on mine.
The PMPC's on the tweeter circuit bypassed with DFFC for the exact value.
I used DMPC with a PMPC and a DFFC for the woofer.
I only did this to save money because I already had two 4.0uf DMPC & PMPC from the previous crossover.
I do have to say that there is NO hint of sibilance that I can hear AT ALL with this setup.
I also unwound higher value inductors to get my precise match between speakers.
I also paralleled two 20Ω 10W resistors for the tweeter circuit series resistor to not only get more power handling but also to knock out any little bit of inductance that may be in them.

Well after a bit of listening I do notice that they don't do quite as good of a job at bringing out softer sub-passages as my RS100-8 Full-Range speakers.
Otherwise I am QUITE happy with these.
I will start experimenting with toe-in/out to try and widen the 6" wide sweet spot.
That being said, at about 8 feet distance the sweet spot widens to about 12" and it is about 7 feet high.

So....Now that I have adjusted placement of the speakers 6" from the rear wall and baffles perfectly in line with each other I have a nice 2 foot wide sweet spot at only 6 feet distance.
Being that the speakers are only 3.5 feet apart I think a 2 foot sweet spot that close is really good.
