Silverline SR17.5 crossover modifications?

Reynold853, Thanks, that was just the sort of response I was hoping to get -- practical, not theoretical, detailed and specific. The crossover upgrade consideration is back on!

Reynolds853, YES! I would be grateful to have the photos of your crossover work. Thanks again for a great post.

At first I was eager to do a makeover, now I'm not so sure.
I'm not anxious to change the character of my speakers, just make what is BETTER, not that I'm complaining, mind you. Perhaps just changing one part instead of all? Maybe the wiring?

Rieff, Thanks for the tip. I'll give Bill Legall a call...

Rieff, Thanks, I did talk to Bill and he settled the issue for me. "If you like what you hear, don't mess with it. More expensive parts doesn't mean better sound. Good speaker manufacturers like Silverline carefully voice their speakers and changing crossover parts will change the character of their sound. They probably spent many months if not years experimenting and tweaking to get it just right." Enough said. I am now disabused of the notion of touching the crossovers!

Alan uses a 1st order crossover with a custom inductor and one Chinese cap and one Chinese sand-cast resistor. I won't touch the inductor but it sure looks like the cap and resistor can be improved. Like Reynolds 853, I'm going to try replacing the caps and resistors -- but leave the old parts in place on the board for now, just in case. I'll replace the resistors first and see how it sounds. Then move on to the caps. I bought Dueland resistors and Mundorf Silver/Oil caps. It's a simple job.
