Modifying Philharmonic 3 crossovers

Resistors: Mills
Inexpensive, very good, dead accurate and thermally stable. I'm not a fan of Duelund's as they are deliberately not thermally stable. No thank you. :)

As for bypassing,that's what I was discussing with CMR caps above 5 uF. Use a 0.1uF jupiter or Audyn TrueCopper ($20) to bypass them, in other words, put in parallel with the main cap.

What I do while testing is I use alligator clips to attach the Audyn where I think it may make a difference and listen.

Use Mills. Use same value CMR caps (although Reliable Capacitor Theta are my personal favorites). Don’t bypass.

Hi, thanks guys for your responses. I'm seeing varying opinions regarding bypassing. Are there down sides to bypassing?

So I just soldered all the Clarity CMRs and CSA capacitor and the Phil 3 speaker sounds fantastic! The speakers sound a lot more 3 dimensional and much more atmospheric and organic. Thank you everyone for the advice and especially to Eric! This would have been much more difficult without you guys' help. I did receive the mills non-inductive resistors and plan on replacing the ones in the speaker this weekend. I hope you guys have a bit more patience but I wanted to know more about inductors. Do they make a big difference like the capacitors? Do you guys have a certain brand that you guys would recommend? From the way that the inductors in my speaker look like, I believe I have ERSE inductors. Are the a good brand?

When I upgrade speaker crossover inductors, I like to change iron core inductor to air core. Air core inductor will be much bigger than iron core in order to keep the DCR as close as possible.
