Fk that bump, not too loud, and not too much it will add if you even have those lots of infrasonic stuff.
Ok. But what about just linear phase low cut or shelves? It will not add wooomp prering in infrasonic area. You have transient punch in 20 Hz area? It will not smear it, because if there is a constant, not too loud dirt bubbling in infrasonic area, preringing will not spoil it. It is dangerous to use bell filters on kick etc.... But linearphase filtering in infrasonic area is not a problem. Shelves are safer a bit. Lower impulse responses than high and max... That's it

 

Very funny. And what IS the Sister Site exactly, please?

 

No, no, he's serious, message sent.

 

first rule of the sister site club is that you never talk about the sister site
