Hi,
I built 4 coaxial speakers according to the B&C CX10.64 reference design. For initial testing, I bi-amped them. Completely blown away by the sound !!!
Next step is to build and install a crossover. Unfortunately, the information the B&C provides is limited to the schematic with component values. (see attachment)
I understand, of course, that they don't want to name brands here, but I get a little lost when searching for components.
Can you help me on my way with this. There is so much information that I can't see the forest for the trees.
I had already understood that low resistance coils (thick wire) and high voltage capacitors help reduce distortion.
But where is the sweet spot? The speaker in question is a coaxial type with 500W continuous power.
Also, I think it would be useful to use some kind of protection to protect the HF driver. But what?
Any other things I should pay attention to?
Thanks for your answers.
Regards,
Johan

They also offer complete crossover for this coaxial driver and it is also suitable for the suggested design.
B&C FB10CX64
I think you can find some component value on the picture. Watt, voltage
In the FB464 XO they put protection light bulb for the HF but seems that they didn't put protection on this one.
TLHP product page
For the price I think it's quite competitive.
I use the DCX464 compression coax and their FB464 XO and I'm quite satisfied.
I tried to purchase the component before but realized the inductor is quite costly and won't save me much.
PS: the XO I got has a bit of small of organic solvents. Seems coming from the inductor.
But this shouldn't be a problem if the XO is in the box.

Thanks for your anwser.
I have already bought the empty PCBs a while ago (TLHP F300 crossover board)
Based on the picture of the completed xover and what I have read on the Internet so far, I selected these components:
Are these choices ok?
Thanks!

Hi joble,
Did you end up making your own crossovers for the B&Cs? I am currently in the same boat and am curious if you did build these with components you listed? Thanks!

Hi,
Yes, in the meantime I have built the crossover with these components. But due to lack of time, it has not been tested yet.
Hopefully, I can do this next week.
I'll post the results here.

Definitely let me know, Id love to see what you think and check out some measurements. I know that B&C makes the crossovers for these but I cant help but think a DIY would be a better option for me. thank you and looking forward to the results!
