I had the same thought as stabie regarding all of the signal to the mid/high section going through crossover capacitors that block low frequencies and DC. As an experiment, one might take either a 5 or 10-watt, 100-ohm resistor or a 1-watt, 1000-ohm resistor and place it in parallel with the mid/high section at the speaker cable terminals. The 100-ohm or 1000-ohm additional load would be negligible to the amp, but would allow very limited low frequency or DC current flow, should that solve the problem. Just don’t create a short in the process of installing the resistor! If the resistor solves the problem while not affecting the quality of the sound, and if the resistor never seems to get very warm, you might just consider installing the resistor in a way that allows it to safely remain installed.

Disclaimer: If you are not confident about doing this, don’t!
