For what it's worth, I just used 10AWG air coils from North Creek to do Magnepan MG1.6. Good results. I considered various foil inductors, but they do have some reliability drawbacks, and I did hear that Magnepan discourages foil inductors. Lower AWG sizes (heavier wire size) are not available in foils. There may be significant differences between foil and wire, but similar size wire air coils should be equivalent (although the various manufacturers will argue otherwise).
Alpha-core or perfect lay inductors for upgrading?
I'm trying to find out if one type of inductor is better suited for one application than another...one for the mids and a different type for the woofers. Are Solen Hepta-litz air core one of the best available? How do they compare sound wise to Alpha-core inductors?
