SPECIFICATIONS

Revel utilizes proprietary measurement methods in the design and
specification of our loudspeakers. Our research has developed a
series of tests that represent a great leap forward in making mea-
surements that dramatically contribute to our goal of accurately
reproducing music or film.
Sensitivity:

Filters (Crossover):
Frequency Responses:
86 dB SPL, with 2.83 V rms @ 1 m
(4 pi anechoic)
Sensitivity provides an indication of how much amplifier power is
required for the loudspeaker to play at satisfactory volume levels.
This conservatively-rated specification indicates moderate sensitivity
and denotes that SALON does not require huge amplifiers to
achieve realistic levels in all but the largest rooms.
6 ohms (nominal), 3 ohms (minimum)
Impedance indicates whether the speaker system presents a "hard"
or "easy" load on the amplifier. A minimum impedance value of
3 ohms, together with moderate phase angles, signifies that any
competently-designed amplifier can easily drive SALON.
4-way, 24 dB per octave, (4th-order) acoustic
response at 125 Hz, 450 Hz, and 2.2 kHz
The steep filter slopes ensure good acoustical behavior in the
crossover regions, with a minimum of acoustical interference, along
with low distortion and wide dynamic range. The filters feature
point-to-point hand wiring with specially selected components.
Woofer and tweeter filter boards are physically independent and
include a provision for bi amping or bi-wiring.
In-Room Response;
+ 1 dB from 25 Hz to 12 kHz
In-room response is a breakthrough measurement that, in a single
curve, closely correlates to sound quality and has been a goal of
loudspeaker engineers for years. Research, and simple observation,
reveals that ubiquitous "on-axis" response curves often cannot dis-
tinguish between two loudspeakers with radically different sound
quality. This SALON specification is even more powerful when it is
taken in context with the other measurements presented here.
In-Room Response Relative to Target Response;
+ 0.75 dB from 25 Hz to 20 kHz
A target response is the ideal response goal and is not flat at the fre-
quency extremes and is used when the ideal reference is not a "flat"
line. A target response must be tailored to the loudspeaker's intended
application and takes into account the acoustic impact of the loud-
speaker's location, such as freestanding, or placement near a wall.
First-Reflections Response;
+ 1 dB from 25 Hz to 17 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 SALON will remain
accurate, even in the presence of strong reflections.
