KEF 103.2 Help

Hoping someone can help me here. I bought a pair of KEF 103.2’s from an estate sale for $75. One works great, the other doesn’t. I ran a frequency test and the faulty speaker doesn’t play lows, however, the tweeter works fine. I thought it might be the woofer so I swapped the woofer from the good speaker and hooked it up to the faulty speaker, but it still wouldn’t play. I also opened it up and the caps look ok (not leaking as far as I can tell). Any ideas about what might be going on, how I should diagnose it, or where I should try and get it fixed? I am powering it with a NAD C368.  Thanks in advance.

You can test a woofer directly w audio signal at low power, listen for voice coil rub
use a fused line

The relay was marketed under S-Stop
they were wonky even when new, I would go around that as Eric said

Thanks for the replies.  I'm pretty much a noob with this stuff so wouldn't know what voice coil rub sounds like.  However, I've read that the caps in the S-Stop leak and corrode the traces on the circuit board which lead to the dead woofer.  I have a feeling that is what is happening.
