Wind wooshing noise in sub speaker

[Extreme_Boky]

The freeze spray can not change the lowpass frequency, use very short bursts and focus them only on a single semiconductor/component at any one time. Do not forget to spray diode(s).

No sorry, I meant could a problematic bridge rectifier cause the low pass problem? I am basically getting a full spectrum signal through with the low pass working in parallel by the sound of it. It doesn't even sound like a sub at the moment, just a bassy normal speaker.
Am I looking for excess heat, or expecting something in the signal to change?

Could you tell me the voltage of the transformer, which burned out and has no specification?

Maybe check the supply voltage(s) first to make sure that's OK.
