    How to choose rossover coils?

    Hello everyone! My name is Ari and I have finally taken steps to build 4344 inspired speakers. I've been roaming the forums and thinking of this project for over 15 years! I don't have room for 4345s and these will probably take up the entire living room. Since 2122H are difficult to source I am using 2123Hs and the 4344MKII charge coupled crossover below.

    As I am acquiring parts, I ordered coils from Jantzen via HiFi collective in the UK. My question is how does DCR of a coil affect the crossover? According to the list below L2 is a .6mH with a DCR< 0.5 ohms. When I ordered this exact part the coil wires are 24 AWG gauge which seems very small. Is it better to use a coil with larger wires which will lessen the DCR? How will this change the crossover if at all? How do you guys best match coil specs?

    Also how much would I benefit from air coils vs iron cored coils in different parts of the crossover?

    Thanks for your help!
