All good. I have a new capacitance meter on the way as my old one has seemed to have gone AWOL.
I am fairly certain that the 2.5mf cap in the tweeter circuit on this particular speaker is well out of spec. When I do a "dirty" test of it using a regular DMM, it drops way faster than the other side's same capacitor does which indicates that some of the internal "film" has been fused ultimately changing its overall capacitance.
So I have also ordered new 2.5mf Sonicap Gen Is for the tweeter circuit caps and decided to be proactive with the mid-range circuit and grabbed 4 6.8mf ClarityCap PXs for those.
These are the same values as stock but instead of going back to the stock Solen caps (which I tend to use on my DIY speakers and other crossover rebuilds), I decided to go with the Sonicaps as they have a great reputation for a nice smooth transparent sound and the ClarityCaps as they are a nice reliable workhorse capacitor.
Visual inspection of the inductors shows no physical damage or delamination which would indicate thermal damage. But I am not going to invest in a DCR meter to check them. Those 1.0mh and 1.8mh inductors are dirt cheap anyway if they need to be replaced.
Alan Yun (the man behind Silverline Audio) subscribes to the old adage of KISS (Keep It Simple Stupid) of crossover design and uses first order slopes on his crossovers so even in a 3 way crossover, you only end up with 2 inductors and 2 capacitors (the 2 6.8mf caps on the mid-range circuit are paralleled for a 13.6mf "single" capacitor).
