I should have asked this question on my first post about the Lyra/xover/inductors. There is a 60uf cap shown on the low pass. Should I use a 60 npe or go for a combination of 60 with a higher quality cap. I have only built one pair of diy speakers. I would really like to get this one right the first time. Extra cost is worth it. Thank You.

Any time you have the chance to use better or higher quality components - go for it. As long as the value is the same in the end it shouldn't make a difference how you get there.
