C50 loudspeaker.
SPECIFICATIONS (Continued)
Frequency Responses: Listening Window Response;
(Continued) ±1.0 dB from 70 Hz to 18 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 @ 62 Hz (-6 dB @ 50 Hz, -10 dB @ 38 Hz)
Studies have shown that the -10 dB low frequency extension specifi-
cation 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.
