Ok I started testing. I pulled the sock off the right speaker. I disconnected the spade connections to the woofer, mid and tweeter so the crossover would not affect the pure resistance readings.
Tweeter 4.1 ohm
mid 4.2 ohm
woofer 4.2 ohm.
These readings seem to be the same (allowing for slight meter difference) as those listed in the speaker diagram attached.
No delam was found in tweeter or mid wires. There is slight delamination on the woofer. Maybe up to an inch on bottom but not all loops and up to 1/2 inch on top again not all loops. There was only one woofer trace with a delam in the middle and that wire was delaminated about 3 inches where the vibration button is.
The crossover only has one bipolar cap and that is on the woofer 50uf. would not expect the film caps to go bad on the tweeter (solen) and mid (elpac).
I hope to pull the sock off the left speaker and insepect it soon.
