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.

Subwoofer Out connectors: If you are using more than one Performa3 subwoofer in the system, connect the Subwoofer Out connector to the additional Performa3 subwoofer’s Input Connector. Balanced (XLR) and unbalanced (RCA) connectors are available. Both outputs are 0dBv (nominal)/+20dBv (maximum). The XLR output is pin 2 high.
High-Pass Out connectors: Use these connectors to send a high-pass filtered signal to the main (left/right) amplifier’s inputs. Balanced (XLR) and unbalanced (RCA) connectors are available. Both outputs are 0dBv (nominal)/+20dBv (maximum). The XLR output is pin 2 high. NOTE: The factory-default high-pass crossover setting is at 80Hz with a 24dB/octave (4th-order) slope. You can change these settings using the Revel LFO programming software. See the Revel Performa3 Subwoofer User Guide for more information.
Input connectors: Connect these to the outputs of a stereo preamp or connect a surround processor's subwoofer output to either the left or right input. Balanced (XLR) and unbalanced (RCA) connectors are available. Both inputs are 0dBv (nominal)/+20dBv (maximum). The XLR input is pin 2 high.
12V Trigger In/Out connectors: When the subwoofer’s Power Mode Switch is set to “Trigger,” the subwoofer will automatically turn on when 5V – 12V is present at the 12V Trigger In connection and will turn off when the voltage at this connection is removed. Whenever the subwoofer is on, a 12V trigger signal is available at its 12V Trigger Out connector for use with additional Performa3 subwoofers, or another triggerable device.
USB connector: To program the subwoofer’s room equalization and high-pass and low-pass crossover characteristics, connect this USB Type B receptacle to the USB receptacle of a computer that is running the Revel LFO programming software.
Subwoofer Gain control: Use this control to adjust the volume of the subwoofer relative to the system’s other speakers. (The Gain control can be disabled using the Revel LFO programming software.)
Power Mode switch: This switch determines how the subwoofer will turn on and off:
• When this switch is set in the “Auto” position and the Power switch is set to “On,” the subwoofer will automatically turn on when it first detects an audio signal at any of its inputs, and will automatically enter the standby mode after it has received no audio signal for a period of time (30 seconds to 120 minutes) you can set using the Revel LFO programming software.
• When this switch is set in the “On” position, the subwoofer will turn on when the Power switch is set to “On” and will remain on until the Power switch is set to “Off.”
• When this switch is set in the “Trigger” position and the Power switch is set to “On,” the subwoofer will automatically turn on when a voltage is present at the 12V Trigger In connection and will remain on as long as the voltage is present. When the voltage at the 12V Trigger In connection is removed the subwoofer will automatically turn off.
Power switch: When this switch is set to “On,” the subwoofer’s on/off status is dependent on the setting of the Power Mode switch (see above). When the Power switch is set to “Off” the subwoofer is turned off and cannot turn on automatically.
We suggest setting the Power switch in the “Off” position if you will not be using the subwoofer for a long period of time, such as when you’re on vacation.
Power Cord connector: Plug the supplied power cord into this connector and into a working unswitched AC power outlet.

SUBwOOfER PlACEMENT CONSIDERATIONS
When using subwoofers within the limited confines of a typical home theater room, the reflections, standing waves and absorptions generated within the room will create peaks and dips in the bass response that can vary greatly depending on where the listeners are located in the room – a listener seated in one location may hear an overabundance of bass created by a response peak at that location, while another listener only a few feet away may hear a considerable lack of bass created by a response dip at that location.
The subwoofers’ locations within the room (along with the room’s dimensions) also have a profound effect on the creation of these bass response peaks and dips. Careful subwoofer placement alone cannot compensate for all bass response peaks and dips throughout a room, but careful subwoofer placement can eliminate or significantly reduce the largest response dips.
It is important to reduce response dips throughout the room as much as possible via proper subwoofer placement because equalization cannot be used to compensate for large response dips. For example, using equalization in an attempt to restore a 13dB response dip requires that the subwoofer amplifier delivers twenty times the power at that frequency. This can quickly overdrive the subwoofer amplifier into clipping, which will significantly degrade audio quality.
In almost any room, placing the subwoofers in corners will produce the fewest large bass response dips and will also produce the most large bass response peaks. With the subwoofers so placed, you can then use the Revel LFO programming software’s sophisticated room equalization capability to compensate for the response peaks, resulting in superb bass performance.
