Low frequency response
Shows the loudspeaker-room response to a low frequency sine
wave, swept between 0 and 250Hz. The ideal low frequency
response would be smooth. A peak in the response indicates a
resonance at the corresponding frequency. A dip in the response
indicates absorption or cancellation at the corresponding frequency.
To display the value of the curve at any point
