i noticed a tapping sound coming from my sub the other day, def tech pf15.
just like someone is tapping on a microphone.
it is very low but noticeable if the room is quiet.

the sound is present with/without source connected, with a different outlet for power, or even knobs/switches moved around.
it works fine otherwise.

i'm curious what it is but more in how to correct it.
