Blog: Upgrade Inductors with Care

Since the topic of upgrading crossovers comes up a lot I wrote a post that I hope you'll find useful.


I find it interesting that Rockport, which don’t skimp on price when building their speakers, don’t use foil inductors. They claim they do not sound as good as perfect lay coil inductors.

Anytime I every upgraded my speakers or built a kit pair, I always used foil thinking it was the best. But I never thought to compare them.

@agisthos over in the DIYaudio forum you'll find builders who have, and many prefer iron core for woofers due to bass slam.
