ABOUT THIS DOCUMENT
This quick-start guide contains all the information you will need to
unpack and initially place your Revel Performa3 subwoofer, connect it to
the rest of your audio system, turn it on and have a first listen. To take
full advantage of all the performance your new subwoofer is capable of
delivering, please go to the Revel Web site (www.revelspeakers.com)
and download the free Revel Performa3 Subwoofer User Guide and the
Revel LFO (Low-Frequency Optimization) software. The User Guide and
software provide you with an extremely sophisticated way to optimize
your subwoofer's performance for your particular installation.

ABOUT REvEl PERfORMA3 SUBwOOfERS

Thank you for purchasing a Revel Performa3 subwoofer. The B112
and B110 are powered by a 1,000-watt RMS (2,000-watt peak)
internal amplifier and feature a custom-designed transducer that
combines a new level of low frequency nuance and refinement with
unprecedented brute-force capabilities in a unit designed for use in the
home. Combined with the internal amplifier's large power capability,
and the extensive programming and room equalization capability of
the companion Revel LFO (Low-Frequency Optimization) programming
software, the result is a new standard of superb bass performance and
adaptability for home entertainment systems.
The B112 and B110 feature 12-inch and 10-inch versions, respectively, of
a brand-new low-frequency transducer that has been designed specifically
for use in these two subwoofer models. The primary design goal for this
new driver was to produce very low frequencies at extremely high SPL
(sound-pressure levels) while at the same time maintaining extremely low
distortion - requirements that usually remain mutually exclusive. This new
unit maintains a precise engineering balance between the voice coil, spider
and surround that produces linear motion of all three for lower distortion by
incorporating CAD/FEA optimized high-linearity motor geometry:
• The extremely long (50mm) two-layer copper voice coil gives this
transducer a very high Xmax, dramatically increasing output.
A fiberglass voice coil former helps the voice coil withstand
high temperatures, reducing power compression and helping
increase output. A spacer added at the top of the voice coil former
maintains motor geometry, creates a solid attachment joint and
prevents deformation of the voice coil at high outputs. The spacer
also eliminates the typical single fulcrum point between the spider
and cone on the voice coil former, minimizing voice coil rocking
modes during hi-power operation.
• A high-temperature Nomex
®
design that evenly distributes mechanical stress, helping keep the
cone's motion linear during high-excursion operation.
• A nitril/butylene rubber surround uses patented Plus One
technology that increases the transducer's radiating area (Sd),
increasing volume displacement and output.

The coated cellulose/pulp cone and dustcap assembly is vented under
the dustcap to aid in the exchange of air, which reduces acoustic losses
and increases output.
The transducer's massive magnet assembly (30.6 lb in the B112; 24.3
lb in the B110) features a triple-stacked vented ceramic 5 magnet with
flared vents that reduce turbulence, which improves airflow, increases
output and reduces distortion. Dual symmetrical magnet shorting rings
and an extended top pole create a symmetrical magnetic gap field that
increases power handling and reduces power compression further
increasing output. A 15mm-thick top plate improves heat and flux
distribution for lower distortion.
The cast aluminum frame is fully vented to minimize acoustic losses
caused by excessive back pressure. This frame also maintains
dimensional stability and precise mechanical tolerances, allowing the
transducer to be manufactured and assembled to a high degree of
precision.
The B112 and B110 enclosures are formed with contiguous wood layers
that prevent splitting. They feature strategically-oriented bracing that
eliminates the possibility of enclosure-induced coloration. The beautiful,
modern enclosure is finished in high-gloss piano black or genuine
American walnut in a process (developed and overseen by Italian luxury
cabinet makers) that exceeds automotive finish quality.
Your Revel Performa3 subwoofer is designed to be used along with our
Revel LFO programming software, which is available as a free download
at www.revelspeakers.com. The software configures the DSP processor
inside your Performa3 subwoofer, which provides up to ten independent
equalization points, each with user-determined frequency, amount of
gain/cut and filter Q (bandwidth). This provides you with an extremely
sophisticated way to optimize the subwoofer's performance for your
particular installation, listening room and seating arrangement. In
addition, the software also provides programming for the subwoofer's
internal crossover system, as well as speaker delay and polarity
settings. All of these processing options can also be independently
applied to the subwoofer's left and right high-pass outputs.
During development, every Revel loudspeaker model is compared to
competitive models in our unique position-independent double-blind
listening lab. This process utilizes the latest psychoacoustic research
to assure that these listening tests are valid, enabling us to verify that
all Revel loudspeakers are superior to their competitors before they are
allowed to go into production.
