Upgrading crossover?


Has anyone done an upgrade to factory speaker crossover with better quality components and got good results?
I had opportunity to look at the crossover while upgrading friend’s PMC FB1 to + version, and I noticed that components were not of a high quality, inductors with ferrite core, electrolytic caps, resistors of 5%.
What are your thoughts of replacing these elements with better quality ones of the same value, inductors with air core (for example Alpha core Ribbon inductors), Solen caps, etc?

Always a good idea to upgrade if you are up to it. I've done about 15 different pairs with great results. Always make a quick schematic of the crossover so you don't confuse wiring and components. Do only one speaker at a time and try it first, then proceed if successful, otherwise use the unmodified crossover as the template.

If you are doing $300-$500 range the Solens are great. Above that go to the Auricaps. Rewire with better cable.

Might pack corners with rope caulking (Mortite)to dampen cabinet. If the speakers are biwirable, internally solder for only one set of terminals. Use good quality silver solder, not lead. Have fun.
