Simplified Loudspeaker Measurements at Low Frequencies

The effective free-field frequency response and harmonic distortion of a direct-radiator loudspeaker system can be measured at low frequencies without establishing free-field radiation conditions. The technique is based on measurement of the acoustical pressure within the system enclosure and is simple and inexpensive. It provides useful response measurements up to about 200 Hz, and harmonic distortion measurements up to about 100 Hz.
