X-Curves
For small rooms (dened as less than 5300 cubic feet
or 150 cubic meters), ANSI/SMPTE 222M calls for a
modication of the X-curve with at natural response to
2 kHz and then a 1.5 dB per octave roll off above 2 kHz.
This curve is useful when mixing in a small room and be
playing back in a large room.

Another variation is to begin the high-end roll-off at
4 kHz and roll off 3 dB per octave instead of 1.5 per
octave.
