small-room X-Curve : See X-Curve.

X-curveX-Curve : Transfer curve. See transfer characteristic.eXtended-Curve. As opposed to the Academy curve, the X-Curve is also known as the wide-range curve and is codified in ISO Bulletin 2969. Specifications call for pink noise, at listening position in a re-recording studio, or two-thirds of the way back in a theater, to be flat to 2kHz, rolling off at 3dB per octave after that. The small-room X-Curve is designed to be used in rooms with less than 150 cubic meters, or 5,300 square feet. This standard specifies flat response to 2kHz, rolling off 1.5dB per octave after that. Sometimes a modified small-room curve is used, starting the roll-off at 4kHz, rolling down 3dB thereafter.
