Silverline SR17.5 crossover modifications?

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

I own the Bolero speakers and love them so much.

I also like Mundorf caps and wonder what Alan uses for cap brands in this speaker.

The crossover is in the bottom of the speaker and I think the bottom plate needs to be removed to check out the prts.

I can't image the speaker sounding anymore right, but now I wonder.

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.

Can you update us on your findings regarding your mod?

Earlier this week I ordered a pair of Duelund VSF copper capacitors to replace the Mundorf S/G/O in my 17.5s.

My goal is to move from "slight top-end emphasis" to "tonal balance near perfection" as Tony Gee wrote.

It may take a while to receive the VSFs and give them a fair amount of break-in, but I will update this thread in due time.
