Ordered This From Madisound

It is the ONLY Electrolytic Cap in there, all the rest are Mylar.
This Cap is about 2.5 inches long. I could not find a physically close in size 4 mfd 100 volt Electrolytic Cap. Today's Non Polar Electrolytic Caps are physically tiny, so I ordered a Bennic Metallized Polyproplyne Cap. The circuit calls for a 10% 4 mfd 100 volt, so I ordered 5% 3.9 mfd 250 volt cap.

I wish I had a crossover schematic, so I can understand WHY all the caps are Mylar, except the one Electrolytic ?

These Cerwin Vega V 36D speakers are from the early 90's I think, so that would make them 27 years old, kind of a long time, for an Aluminum Electrolytic.

I figure the Mylar Caps, are still good.

What about the speaker diaphragms, how long do they usually last, and how do you tell when they are going bad ?
