REVEL PERFORMA M22

Specification

Value

Definition

Sensitivity

86.5dB SPL
with 2.83Vrms @ 1m (4 pi anechoic)

Indicates the amount power the associated power amplifier must deliver to drive the loudspeaker at reasonable volume levels. Conservatively-rated specifications indicate moderate sensitivity, meaning that a massive power amplifier is not required to drive Revel loudspeakers to reasonable volume levels in large listening spaces.

Impedance

6.4Ω (nominal)
4.8Ω (minimum @ 160Hz)

Indicates whether the loudspeaker presents a “difficult” or “easy” load on the associated power amplifier. Combined with moderate phase angles, a minimal impedance specification of 4.8Ω allows any reasonably designed power amplifier to drive Revel loudspeakers.

Filter Network

Two-way, high-order @ 2.2kHz

Indicates the acoustical characteristics of the filter network. Steep filters indicate an optimized filter network that produces minimal acoustical interference, low distortion, and expansive dynamic range.

In-Room Response

±1.0dB
from 46Hz to 16kHz

Indicates sound quality in context with other specifications. A breakthrough measurement, this specification closely correlates to sound quality in a single curve – a long-standing goal of loudspeaker engineers. Research and observation reveals that ubiquitous “on-axis” response curves cannot distinguish between two loudspeakers with radically different sound qualities.

Target Response

±0.75dB
from 46Hz to 20Hz

Indicates sound quality in context with the individual loudspeaker’s application, considering the acoustical impact of its placement. An ideal response goal, a target response is not flat at either end of the audible spectrum and is used when the ideal reference is not a flat line.

First Reflections Response

±1.5dB
from 45Hz to 15kHz

Indicates the response listeners hear in relation to the first reflections from walls, ceilings, and floors. This specification indicates that Revel loudspeakers will remain accurate, even in listening rooms that cast strong reflections.

Listening Window Response

1.5dB
from 45Hz to 16kHz

Indicates the on-axis response of the loudspeaker. An improved “on-axis” measurement, this specification reduces the visual confusion of inaudible interference. It retains full accuracy without using “spectral smoothing,” which results in significant data loss.

Low-Frequency Extension

-10dB @ 36Hz -6dB @ 41Hz -3dB @ 48Hz

Indicates the low-frequency response of the loudspeaker. Studies have shown that the –10dB specification best correlates to controlled listening tests. At low frequencies, most loudspeaker and listening room combinations demonstrate significant “ room gain,” which produces an increase in levels as frequencies decrease. Unlike the –3dB specification, the –10dB specification reflects the steepness of low-frequency roll-offs.
