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?

If the speakers are more expensive, often times even if the parts seem cheap they have been handselected to meet close tolerances. However, I have always upgraded the crossovers on used or speakers I've purchased at closeout prices. Just changing the crossover caps and putting in good wire makes a large difference worth the 40 to 80 dollars spent. (kimber cable 8vs ,if thats the blue and black wire, was always made a a great hookup wire). Anyway the upgrades have always I have a pair of sound dynamics rts-5s that I modified, and there are fairly good pics of the crossove if u want to take a gander.
Please bear in mind that series resistance in inductors are a integral part of any serious cross-over design, so replacing inductors shoud be done with the outmost care. Other than that have fun.
Greetings, I now this is a little off your thread, but you also may want to consider upgrading your speakers internal wiring.

I recently rewired my Klipsch LaScalas', whose original wiring was still like new. I used DH Labs hookup wire. Total cost was about $70.00.

The improvement was considerable, I would have never believed that just upgrading wire could make such a difference. Happy Listening

I have upgraded the caps, resistors and air core inductors on all three pairs of my Klipsch speakers and can tell you for a fact that I HEARD a tremendous difference in sound. I replaced the stock caps with Kimber Kaps, stock resistors with Mills non-inductive resistors, and stock air core inductors with Madisound.

I lived with all these speakers stock for about 5 years, so I was very familiar with the sound. What I heard after I upgraded the crossovers was nothing short of amazing. Trust me, I wasn't TRYING to hear something either to justify the less than $100 in parts cost.

Bottom line: better parts do make a difference.
