X – Curves Explained

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

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