Specifications - REVELL Performa S30 Manual

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.

REVEL PERFORMA S30
22
Owner's Manual
90 dB SPL, with 2.83 V rms @ 1 m
(2 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 the
REVEL PERFORMA S30 surround loudspeaker does not require huge
amplifiers to achieve realistic levels in all but the largest rooms.
Monopole Mode –
6 ohms (nominal), 3 ohms (min.) @ 3.6 kHz
Dipole Mode –
6 ohms (nominal), 3 ohms (min.) @ 355 Hz
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 the REVEL PERFORMA S30
surround loudspeaker.
Monopole Mode –
2-way, high-order, in-phase @ 2.5 kHz
Dipole Mode –
2-way, high-order @ 250 Hz
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
specially selected components. Woofer and tweeter filter boards are
physically independent.
In-Room Response;
±1.5 dB from 90 Hz to 16 kHz
In-room response is a breakthrough measurement that, in a single
curve, closely correlates to sound quality and has been a goal of loud-
speaker engineers for years. Research, and simple observation, reveals
that ubiquitous "on-axis" response curves often cannot distinguish
between two loudspeakers with radically different sound quality. This
REVEL PERFORMA S30 surround loudspeaker specification is even
more powerful when it is taken in context with the other measure-
ments presented here.
In-Room Response Relative to Target Response;
±0.75 dB from 80 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.
