SRS 3.1TL SDA Drivers Not Working

Just picked up these pristine condition 3.1 sDA speakers from original owner , look brand new. Unfortunately looks like the SDA drivers are not producing any sound , with or without the interconnect cable. Both drivers test good with multimeter , and getting sound out of the other eight drivers. Just the two SDA drivers are not working so I assume it is something in the crossover? I was hoping someone could help identify the problem here, I'm fairly new to speaker repair.
I'm also fairly new to SDA speakers, it's my understanding that the SDA drivers should still produce sound even without the interconnect? With the interconnect cable connected I did test continuity and it is inserted properly. Seems like it should be a pretty easy fix but I'm kind of lost

I would carefully check to make sure all the wiring is correct. Schematic, wiring, and troubleshooting guides are found in this thread:

The crossovers could use a refresh/upgrade, but unless there is a broken lead, or cold solder joint, the sound should still go through if wired correctly. -
Okay thanks I'll give it a look. Weird that the same sda driver is out in both speakers

Have you checked for continuity of the SDA cable? If it's pin/blade, only one wire is used. I replaced mine so long ago with a single terminal, I can't quite remember which, but I believe both will still have continuity.

Are you sure they aren't playing at a lower level? The SDA drivers play at a reduced level compared to the main stereo drivers.
