Revel S30 - Manual (Page 23)

Figure 17. Overall dimensions
for the REVEL PERFORMA
S30 surround loudspeaker.
Frequency Responses: First-Reflections Response;
(Monopole Mode) ±1.75 dB from 88 Hz to 14 kHz
First reflection response is a measure of the response a listener hears
that is contributed by the first reflections from the walls, floor, and
ceiling. This superb specification indicates that REVEL PERFOR-
MA S30 surround loudspeaker will remain accurate, even in the
presence of strong reflections.
Listening Window Response;
±1.5 dB from 90 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 @80 Hz, (-6 dB @65 Hz, -10 dB @ 50 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.
