Listening Window Response ±1.0 dB from 72 Hz to 20 kHz Indicates the on-axis response of the loudspeaker. An improved on-axis
measurement, this specification reduces the visual confusion of inaudible
interference. It retains full accuracy without using “spectral smoothing,”
which results in significant data loss.
Low-Frequency Extension -10 dB at 48 Hz
-6 dB at 60 Hz
-3 dB at 70 Hz Indicates the low-frequency response of the loudspeaker. Studies have shown
that the –10 dB specification best correlates to controlled listening tests. At low
frequencies, most loudspeaker and listening room combinations demonstrate
significant room gain, which produces an increase in levels as frequencies
decrease. Unlike the –3 dB specification, the –10 dB specification reflects the
steepness of low-frequency roll-offs.
