If memory is correct it can be found on the Harry Olson (RCA) book called Music Physics Engineering.
If memory is correct the title of this post means that for every octave cut on the left side of frequency spectrum same number of octaves should be cut on the right side. An empirical or experimental observation.
For example 80Hz-5KHz -3dB points is preferred by listeners brains to 80Hz-20KHz or 20Hz-5KHz.
The former would sound too bright. The latter too dull.
Today while removing one Staren 5in driver and replacing it with the Tesla 5in referred to on a previous today's post this important rule was remembered.
Although the Tesla is not as bright it may be more suitable.
And the point of Auratones is simulating radio.
But then the point is a radio made when?
Nevertheless although the Tesla is not as bright, it sounds natural on Billy Jean - Michael Jackson with voice not piecing shouting at you. Mabe that's the point.
The Tesla have a certain dip at mid range too.
