sents the industry’s most sophisticated loudspeaker listening facility,
allowing loudspeakers to be compared as single speakers, stereo pairs, or
multiple speaker groups. Revel’s tests are based on extensive real world
y measurements are critical, human hearing is the ulti-
listening in more than five different environments that simulate a wide
range of residential settings and room sizes. The MLL facility features a
remarkable, exclusive computer-controlled speaker switching stage that
eliminates the problems associated with speaker placement and aural
memory variables. Loudspeakers are placed on computer-controlled,
movable platfor
ms that can quickly be ar
ranged during testing. As a
Page 4
result, the speaker repositioning process takes only a few seconds,
allowing listeners to quickly and accurately compare speakers to each
ther from the same room position and with minimal time in-between
o
odels. All tests are conducted “double-blind.” Once the loudspeakers
m
are installed on the MLL platforms, an acoustically transparent but visual-
ly opaque veil obscures loudspeaker identities from the listening panelists
to prevent human bias from tainting the results. Even the computer oper-
ator is not aware of the loudspeaker identities, as the computer randomly
determines the listening order prior to the test.
ANECHOIC CHAMBERS
While few loudspeaker companies have access to one, Revel has
three different anechoic (echo-free) chambers. Unlike most other compa-
nies, Revel does not depend on electronic anechoic “simulator” testing
methods that often fail to reveal critical performance flaws such as reso-
nances. Revel’s anechoic chambers are state-of-the-art in design, allow-
ing for accurate and useful loudspeaker measurements of complete
loudspeaker models and individual driver elements.
TRANSDUCERS, TESTING & QUALITY CONTROL
Most loudspeaker manufacturers out-source their transducers,
purchasing off-the-shelf tweeters, midranges, and woofers from vendors.
Revel loudspeakers feature proprietary transducer designs found in no
other company’
oducts. These transducers ar
s pr
e exclusively designed,
Page 5
engineered, and manufactured for Revel loudspeakers.
evel engineers use Computer Aided Design (CAD) software to
R
design transducers that are optimized for each Revel model. A powerful
Finite Element Analysis (FEA) system provides a comprehensive computer
imulation of the entire driver assembly, allowing engineers to optimize
s
every aspect of a transducer assembly. FEA produces precise models of
the driver’s magnetic system, which is used to optimize the electro-mag-
netic circuits for each transducer according to the individual driver’s appli-
cation. Transducer components such as cones, domes, surrounds, and
5
centering mechanisms (the spider) also benefit from FEA scrutiny in the
design process.
An in-house Stereo Lithography Apparatus (SLA) is used during
development to help assure very tight tolerances and minimize develop-
ment times. The SLA utilizes a high-power laser to precisely solidify a liq-
uid polymer into the 3-dimensional shapes specified in CAD drawings.

tionally low distortion.
The Laser Interferometer also contributes to the design of the
oudspeaker cabinet. To avoid undesirable coloration, the cabinet enclo-
l
sure must not cause unwanted resonances. Laser scanning the loud-
peaker enclosure allows for optimization of the cabinet design, including
s
proper placement of internal bracing to create an acoustically inert enclo-
sure conducive to the most neutral and honest sound reproduction.
Prior to installation in the loudspeaker enclosure, each loud-
speaker driver complement and associated crossover elements are sub-
jected to rigorous testing as a complete sub-assembly. Components are
tested in an anechoic chamber and then compared to production refer-
ence standards. But even with the tightest production tolerances, slight
deviations still might occur from one loudspeaker to the next. To prevent
this, a technician compares each loudspeaker to the reference standard,
making careful adjustments by hand as needed. All tuning adjustments
and specifications ar
referenced to the loudspeaker’s serial number.
This careful attention to detail allows Revel to achieve unparal-
e then recorded and retained for archive purposes,
leled consistency among all loudspeakers, alleviating the need for
matched pairs. Instead, all Revel loudspeakers are matched within a frac-
tion of a decibel to achieve superior soundstage imaging and accuracy.
Each pair of Performa loudspeakers sounds the same as the original refer-
ence pair as well as the loudspeakers that have won accolades from
reviewers around the world. Physically separated circuit boards for each
Page 7
frequency range prevent degrading mutual interference caused by com-
onent-to-component interaction. The result is distinctly more transpar-
p
ent and distortion-free sound reproduction.
With the premiere of the Ultima Series, Revel earned a reputa-
ion for producing “the world’s finest loudspeakers.” Since then, Revel
t
loudspeakers have won accolades from discerning audiophiles and critical
reviewers alike. Collectively, the Performa Series offers an impressive
combination of advanced design, precision manufacturing, stunning
audio performance, and handsome aesthetics. Individually, each
7
Performa loudspeaker is a standout performer that delivers a perform-
ance as powerful as it is precise.
The following pages detail the unique design, engineering, and
capabilities of each Performa loudspeaker model.
