Monitor-output EQ cannot reliably correct room-mode colorations

Room-correction EQ measures the monitor response at one point and applies a compensating curve. The author treats this as a red herring for budget mixing: you cannot stay exactly in the sweet spot, and a mode’s node is a physical cancellation that boosting merely adds energy into without filling. Physical absorption (bass traps) attacks the root cause across the room, whereas EQ only masks the symptom at one spot and can worsen it elsewhere.

Examples

Adding a +6 dB shelf to fill a bass suck-out at the mix position over-represents the same frequency a couple of feet away, because the null is a spatial cancellation EQ cannot fill.

Assessment

Explain why room-mode correction EQ on the monitor output is less reliable than physical bass trapping, referencing the spatial nature of nodes.
