I'm about to make a new 2-way Xover for the Beymas. This time Xing at 1600hz and a third order Xover on the tweeter section and first on the woofer section. I have now a third order on my smaller 2-ways, VoXDeuX, which I am yet to listen to fully.
I finished the Xover, installed it and had a few listens. I'm not sure this has been a good step. I have read where on the new Zu(s) they use two very efficient large drivers and a tweeter. The tweeter is connected by a single cap. They claim an expensive one. I did look it up and I think about $50 for the cap.
I thought I may go right back to a 1st order Xover and back to a Xing point of 2K. I wound my own choke with heavy gauge enameled copper wire and ferite rod. Two neat layers then a lighter layer proves 1mh. I can trim this back to the 0.56mh I require for a butterworth. The cap is simple just a 4.7uf metalised poly. If I make a Solen split I require a 0.9mh choke and 3.52uf cap (3.3 + .22uf). Here is my hand wound ferite choke.

Funny my early electronics as a 12 year old kid was winding electro-magnets. When wounding this I could apply all the tricks I had developed right back then in winding and securing the winding (e.g laying upside down tape toward the .end to then fold back and hold the ends in). I had a little chuckle to myself remembering the hundreds of magnets I wound.
