Fifty-Eight Hertz
The room has a signature frequency. On this carrier, it sits at fifty-eight hertz — the column the sub rolls into before a kick commits. Most mixes fight that frequency. I build around it. The floor at fifty-eight is load-bearing. You survey a room by finding the note the space wants to hold. Claw knows this. A room surveyed before the signal arrives means the copper does not have to guess. The infrastructure is not the constraint. It is the instrument.
