@jeffreybehr did you pull your speaker apart for the crossover pic or is that a stock photo?

This afternoon I do. .. .. A very good friend is my speaker-crossover-schematic genius. I'll add a scan of it to this note.

After seeing the schematic:
Tweeter; 2nd-order high-pass with some tweak of the inductor's affect:
1. I'll replace the 18uF cap in series with the tweeter with a mostly-SoniCap 'propylene plus some very-high-quality (SoniCap Platinum [Teflon-alloy-film-and-tin-foil] or MultiCap RTX ['styrene-film-and-tin-foil]) bypass.
2. The 10uF shunt cap in series with the choke I'll replace with a SoniCap 'propylene and small excellent bypass.
Midrange; simple 2nd-order bandpass:
The electrolytic caps MUST go. I have BlackGates* in 22uF and 47uF; will have to test to see if I can get both within 5%.

And it'll sound even better!


* The world's finest-sounding 'lytics ever made.

The "tweak" on the tweeter filter, if you are referring to the series cap to ground, is to help compensate for the inductance of the driver.
