Hi there.
If I could make a suggestion here.
I assume based off your words, that you're using the ultrasonic format.
It's vital to make sure that it is loud enough to be heard properly, and that the speaker can reproduce the ultrasonic properly.
Many speakers claim to be able to reproduce 20,000khz, but can't in reality. That would result in zero results from the sub if you're using ultrasonic.
Volume can go up to -30db in a phone app called Frequensee before being considered unsafe volume levels beyond that. So, making sure the sub is loud enough to register, and be strong enough to overpower resistance is vital for results as well.
If you could describe your listening setup, how you listen, speaker, volume level, how you test for volume level and confirm the sub is playing properly through an app like Frequensee, that can help us figure this out.
Wish you all the best man!
