I think i read somewhere, (loudspeaker cook book components within 10%) Never wrong to go with better quality capacitors or wire wound vs iron core inductors. In the end no way to know if it makes a diff or not unless you build both but i went with quality parts most of which came from Solen.ca There seems to be no limit on what you can spend on crossover parts except when the money runs out.

DOG is GOD spelled backwards.
What others think of me is none of my business.
