In my 4435 xover DIY I use chokes with significantly better DCR ratings.

The 2,6mH choke will have appr. 0,17 Ohm instead the original ?0,45 Ohm?

The 18mH choke will have appr. 0,5 Ohm instead the original 1,41 Ohm

Do I need some port retuning?
What improvements are to expect with these chokes?

Thanks!
