Frequency Responses:
Listening Window Response;
(continued)
±1.0 dB from 85 Hz to 17 kHz
This improved “on-axis” measurement reduces the visual confusion
of inaudible local interference, yet still retains full accuracy without
using “spectral smoothing” which results in significant data loss.

Low Frequency Extension;
-3 dB @ 61 Hz (-6 dB @ 47 Hz, -10 dB @ 38 Hz)
-3 dB @ 61 Hz (-6 dB @ 47 Hz, -10 dB @ 38 Hz)
Studies have shown that the -10 dB low frequency extension specifica-
tion is the one that best correlates to controlled listening tests. At low
frequencies, most loudspeaker/room combinations will exhibit signifi-
cant “room gain”, which is an increasing rise in level as frequencies
decrease. In addition, the -10 dB specification reflects the steepness
(i.e., order) of the low-frequency roll-off, which is not significantly
indicated in -3 dB specifications.
