ABOUT THE REVEL® CONCERTA™ B1 SUBWOOFER
Thank you for purchasing the Revel Concerta B1, a high-performance powered subwoofer that perfectly augments Revel Concerta Series loudspeakers in stereo music or home theater entertainment systems. The B1's adjustable controls and multiple connection options also allow you to optimize the subwoofer's performance in any system and listening room.
Featuring a 12" (305mm) woofer with 1-1/2" (38.1mm) peak-to-peak excursion and powered by a 250-watt amplifier, the B1 subwoofer reproduces deep, realistic bass with very low distortion, even at the lowest frequencies and high output levels.
Combining superior form and function, the B1's proprietary woofer is constructed with an anodized-aluminum diaphragm for great strength at high output levels. The spider incorporates a superior-strength Nomex®/cotton blend with optimized geometry for increased linearity. The motor includes a large ceramic-magnet motor system. A 2" (50.8mm) copper voice coil is wound on a Kapton® bobbin for impressive power handling and freedom from compression. The vented center pole facilitates heat dissipation, allowing more efficient high-power handling and low compression.
The B1 cabinet consists of medium-density fiberboard (MDF) walls and extensive internal bracing to reduce cabinet-induced colorations. Rubber padded feet are attached to the bottom of the cabinet for optimal stability, accommodating installations on any floor surface.
Since 1996, the Revel brand has been at the forefront of loudspeaker design. Backed by Harman International's extensive research and design facilities, Revel Concerta Series speakers benefit from cutting-edge development tools, such as:
- A multichannel listening lab allows for double-blind listening tests.
- A laser interferometer enables detailed driver and cabinet analysis.
- Multiple large anechoic chambers provide for precise tests and measurements.
- Finite-element analysis allows for advanced loudspeaker modeling
- A stereo lithography apparatus aids in achieving tight tolerances.
Adding to the proud lineage of Revel Ultima™ and Performa™ Series loudspeakers, the Concerta B1 subwoofer further substantiates the Revel reputation for high-quality, high-performance loudspeakers and subwoofers.

SUBWOOFER PLACEMENT
Below 300Hz, loudspeaker and listener locations have a profound impact on the way sound is reproduced. All rooms have "standing waves," by which certain frequencies are emphasized or diminished. Their complex patterns can combine to introduce tremendous sound coloration at low frequencies.
The Concerta B1's Equalization controls can help to compensate for these effects, but no electronic system alone can fully compensate for the dramatic effects of room acoustics. Every room has locations where "nulls" at specific frequencies occur. These cancellations of the sound are like "black holes," which no amount of equalization can fill. The best results are always achieved through careful placement of both the loudspeakers and the listening position. Preferable placement can be determined through the use of computer modeling programs, or by trial-and-error measurements. For optimal results, find the best loudspeaker and listener locations first, then use the B1 Equalization controls for fine-tune adjustments.
To help determine good locations for the subwoofer(s) and the listener(s), it is recommended that you make high-resolution in-room response measurements. Your authorized Revel dealer can make the appropriate measurements, using suitable equipment to ensure optimal results.
NOTE: Many sound-measurement devices are not accurate enough to properly measure low-frequency performance in a listening room, since room boundaries can often cause modes (standing waves) with very narrow-band peaks and dips. Check with your authorized Revel dealer to confirm that your measurement equipment is suitable for accurate, high-resolution measurements.
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.
We strongly recommend that you install multiple subwoofers regardless of the room's size. Installing a single subwoofer will result in the least consistent bass performance throughout the room. Using multiple subwoofers can cancel some room modes at the various listening locations, resulting in much more consistent low frequency sound quality throughout the listening area. Additionally, it is often impossible to locate a single subwoofer such that large response dips, which cannot usually be corrected via equalization, are not present. The use of two or more properly placed subwoofers can almost always eliminate such dips in response.
PLACING FOUR SUBWOOFERS
When installing four subwoofers, place each one in a room corner. In rooms with more than four corners, use the four corners closest to the listening area.

Video ScreenPLACING TWO SUBWOOFERS
Placement of two subwoofers will be determined by your room's seating arrangement.
Rooms with a single row of seating
Placing the subwoofers in the two front corners will produce the most consistent bass performance throughout a single row of seating.

text_image
Video ScreenRooms with multiple seating rows
Placing one subwoofer in a front corner and the other subwoofer in the rear corner on the same side will produce the most consistent bass performance throughout multiple seating rows.

text_image
Video ScreenPLACING A SINGLE SUBWOOFER
When installing a single subwoofer, be prepared to experiment with different locations to find the one that produces the best results throughout your room's seating area. As in the previous examples, placing the subwoofer in a corner will produce the fewest number of deep response dips, which cannot be corrected with equalization.

text_image
Video ScreenSince listening and speaker locations are equally important, the trial-and-error process can be time-consuming. However, the sonic rewards are well worth the time spent determining the ideal placement locations. Remember that peaks (below the subwoofer crossover frequency) can be minimized or eliminated by the proper adjustment of the Concerta B1's Equalization controls, but dips cannot be corrected via equalization. Therefore, the most important objective is to find locations that result in the minimum number (and severity) of dips. Contact your authorized Revel dealer for assistance in determining the proper placement of your Revel loudspeakers and subwoofers.
After placing the B1 subwoofer(s), begin playback of a familiar music or film source that has substantial bass content. Listen from the primary listening position, increasing the overall volume of the system to a comfortable level. Adjust the Subwoofer Level (volume) control until you obtain the desired blend of bass. Also, test the subwoofer level by playing a recording of a deep male voice. Setting the subwoofer level (or crossover frequency) too high results in unnaturally "thick" or "boomy" vocal reproduction. Bass response should not overpower the room, and should be adjusted to achieve a harmonious blend across the entire audible range.
If you are using a multichannel receiver or processor with a subwoofer output, it's preferable to use the Subwoofer Level adjustment on the processor. Set the B1 Level control to the indicated "Nominal" position.
NOTE: Setting the level of the subwoofer in relation to the left and right front speakers is of critical importance because it is essential that the subwoofer integrate smoothly with the entire system. Setting the level too high results in an overpowering bass response. Setting the level too low negates the benefits of the B1 subwoofer.
MAKING CONNECTIONS
CAUTION: Never make or break connections unless all system components are powered off.

Input Sub In L R Low-Pass Disabled (Normal) Low-Pass EnabledFigure 8: Rear-panel input connectors
This section provides typical examples of cable connections with different system configurations and devices. Review the owner's manuals for associated audio components to determine their connection requirements.
The B1 subwoofer input connectors are located on the rear panel. Two gold-plated RCA connector options are available – Sub In Low-Pass Disabled (Normal) and L/R Low-Pass Enabled – as shown in Figure 8.
In most cases, you'll use the Sub In connector, as it's designed for multichannel use. This input bypasses the low-pass filter, and is the appropriate input for most installations. This connector should be used when there is a dedicated subwoofer output available on the audio processor or receiver.
Some processors incorrectly label the subwoofer output as LFE; others offer both an LFE and a Subwoofer output. If there is no labeled subwoofer output, use the LFE output. If the output has labeled connections for both LFE and Subwoofer, use the Subwoofer output.
The L (Left) and R (Right) connectors on the rear panel of the B1 are for use with 2-channel applications, where there is no dedicated subwoofer output available. These inputs are automatically crossed-over by the adjustable Low-Pass Crossover control on the rear panel. Having the low-pass filter enabled helps offset the fact that most 2-channel systems do not perform any high-pass filtering on the main speakers, minimizing the advantages of using a subwoofer. These connectors should be used in 2-channel applications where the receiver or preamplifier lacks a dedicated subwoofer or LFE output.
NOTE: The Concerta B1 subwoofer has a third connection option – wireless connection is also available when coupled with the optional TX1 transmitter. Refer to the "Wireless Connection" section found later in this manual for additional details regarding this option.

This configuration is for use with 2-channel preamplifier/power amplifier combinations or 2-channel receivers that have full-range outputs for the left and right channels. The internal low-pass filter in the B1 is used to limit frequency range of the subwoofer, preventing undesirable overlap with the main loudspeakers.
- Connect an RCA patch cable between the left main output on the receiver/preamplifier to the L(eft) Low-Pass Enabled connector on the B1 rear panel, as shown in Figure 10.
- Connect an RCA patch cable between the right main output on the receiver/preamplifier to the R(right) Low-Pass Enabled connector on the B1 rear panel.
NOTE: This configuration applies to receivers with preamplifier outputs or to preamplifier/power amplifier configurations in which there are two sets of Main outputs. If the receiver has jumpers from the Pre- or Main-Out to the Amp in connectors or if the preamplifier has only one set of Main-Out connectors, a
Y-adapter should be used to send the same signal to both the main power amplifier and the subwoofer(s). Tape Out or Record Out connectors cannot be used.

SUBWOOFER OPERATION
The rear panel of the Concerta B1 subwoofer, shown in Figure 14, contains all of the available connectors and controls. The Input section of the rear panel was discussed in the "Making Connections" section, earlier in this manual. The subwoofer controls are discussed in this section. For more information on the wireless connection option, refer to the "Wireless Connection" section found later in this manual.
POWER INDICATOR LED
The Power Indicator LED identifies the current state of the B1 subwoofer. The subwoofer has three different powered states — each identified by a different color. The Power Indicator LED reflects the color of the current power state. The color and the state each color indicates are:
Red: Standby – the B1 automatically enters Standby if no signal is detected from the system for 10 minutes.
Green: On – as soon as a signal is detected, the B1 powers on.
SUBWOOFER LEVEL (VOLUME) CONTROL
Provides basic volume adjustment for the subwoofer. Begin with this control set to the nominal "12 o'clock" position.
LOW-PASS FREQUENCY CONTROL

text_image
80 100 120 50Hz 150 Hz Low-Pass Crossover Nom. Level Min MaxFigure 15: Rear-panel controls and connectors
Adjusts the variable 50Hz – 150Hz low-pass crossover, which determines the highest frequency at which the B1 reproduces sounds. Set the crossover to a lower frequency setting, between 50Hz and 100Hz, when using larger main loudspeakers that can comfortably reproduce some low-frequency sound.
With a lower frequency setting, the B1 subwoofer concentrates on reproducing the deep bass required by contemporary music and film soundtracks. Set the crossover to a higher frequency, between 100Hz and 150Hz, for smaller bookshelf loudspeakers that do not extend to the lower bass frequencies.
If the frequency control is set too high, the bass sounds "boomy" and can overpower the overall sound of the listening room. If the frequency control is set too low, some low frequency sound may be difficult to hear, or may be absent altogether.
This control has no effect when using the Sub In input or if the Low-Pass Switch, shown in Figure 17, is set to Off (Normal) because in both cases the receiver/processor sets the crossover frequency.
NOTE: This control does not limit the frequency range of the main speakers in the system. The objective of adjusting the Low-Pass Frequency control is to ensure that all frequencies are reproduced while minimizing any overlap between the subwoofers and the main speakers. Having both the subwoofer and main speakers reproduce the same frequencies should be avoided, as it results in very irregular response, since some frequencies are reinforced when they happen to be in phase while others are canceled because they are out of phase.
PHASE SWITCH

Compensates for the absolute phase of the subwoofer's output relative to the front speakers. Some associated electronics can invert the absolute phase. Use this switch to correct such occurrences. Proper phase adjustment can also depend on variables such as subwoofer placement and listener position. Use this switch, shown in Figure 16, to maximize bass output at the primary listening position.
- Select the 0^ setting to set the B1 acoustic output in phase (0 degrees) with the input.
- Select the 180° setting to invert the B1 acoustic output (180 degrees) relative to the input.
