Frequency Responses:
Listening Window Response;
(continued)
+ 1.5 dB from 45 Hz to 16 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 @ 44 Hz, -6 dB @ 38 Hz, and
-10 dB @ 33 Hz
-3 dB @ 44 Hz, -6 dB @ 38 Hz, and
-10 dB @ 33 Hz
Studies have shown that the -10 dB low frequency extension speci-
fication is the one that best correlates to controlled listening tests.
At low frequencies, most loudspeaker/room combinations will
exhibit significant “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.
