Many of us use some sort of real-time sound level meter to position speakers and/or configure equalizers to get smoothest (i.e. flattest) frequency response at the listening position.
Yet a measured flat response at the upper end of the spectrum might sound subjectively way too bright and a measured flat response at the low end might sound subjectively too anemic. And I'm not talking about problems of calibration with the meter itself.
I remember an "ideal" measured response curve published many years ago by Bruel & Kjaer (or somebody)that addressed this.
I'd love to resurrect this topic, especially since digital correction is such a hot item right now.
