DESCRIPTION
The REVEL ULTIMA SUB-15 features a unique transducer that
combines the brute-force capabilities of sound reinforcement drivers
with the nuances necessary for audiophile sound reproduction.
Combined with the LE-1’s huge power capability, the result is a
new standard of superb bass performance and adaptability for home
entertainment systems.
SUB-15
To ensure uncompressed dynamic range, each ULTIMA SUB-15 is
unique in the following ways:
•
Oversized 4-inch diameter voice coil with flat copper wire
offers higher power handling and freedom from compression
for control of low frequencies during high acoustic output.
•
Extremely long-throw voice coil is capable of 1.5 inches of
peak-to-peak linear excursion, and 2 inches of maximum
excursion for pure reproduction of deep sustained bass notes.
•
Ultra-rigid Kevlar®- and Kapoc®-impregnated cellulose pulp
cone body and dome operate as a perfect piston under all
reproduction conditions.
•
The heavy wall, cast aluminum frame maintains alignment
between the massive 35-pound magnet structure and the moving elements, while offering excellent rigidity.
The ULTIMA SUB-15 cabinet has been optimally designed and
internally braced with the aid of laser interferometry. Integral top
and bottom panels provide a custom look via available finishes.
LE-1
The ULTIMA LE-1’s amplifier section is rated for a minimum
700 watts (rms) into a single ULTIMA SUB-15, and a minimum
1,200 watts (rms) into two ULTIMA SUB-15s under actual load
conditions. A unique circuit can be switched in to provide compensation for room gain. A remote control provides the listener
with wireless control to set optimum performance while seated in
the listening position. The internal FM-2 electronic crossover
offers truly optimized performance for ideal blending between one
or two ULTIMA SUB-15s and any main loudspeakers.

PLACEMENT
SUB-15 PLACEMENT
Due to long wavelengths being reproduced, low-frequency bass
response from the ULTIMA SUB-15 is non-directional and, therefore, the subwoofer does not require specific placement location.
However, optimum results can be obtained by making in-room
measurements to determine the precise locations of all speakers in
your specific listening room. The location of a subwoofer, along
with the listener’s location, have a profound effect on sound quality.
Revel has made measurements in hundreds of listening rooms and
we suggest trying the following ideas to enhance performance:
•
Use a corner placement for the ULTIMA SUB-15, as shown in
Figure 4 below. This will provide the smoothest response in
most rooms. If you cannot measure the response (in order to
find the best location), place the subwoofer in a front corner.
•
If you plan to use two ULTIMA SUB-15s (see Figure 5 on
next page), place both subwoofers together in a front corner,
side-by-side or stacked, or place a subwoofer in each of the
front corners. However, if the room is not symmetrical, only
place the subwoofers together in one front corner.

of a ULTIMA SUB-15 in an
average room.

Figure 5. Preferred placement of
two ULTIMA SUB-15s in a
corner of a larger room.
For very large rooms (e.g., over 3,000 cubic feet or 85 cubic
meters), consider adding another ULTIMA SUB-15 or another
ULTIMA LE-1/SUB-15 system for more bass output (see
Figure 5). Consult your Revel dealer for specific recommendations on your audio system.

For best results, place the ULTIMA SUB-15 near solid walls to
reinforce bass response, and avoid windows which can rattle
and transmit sound to the outside world.
ULTIMA SUB-15/LE-1 11
Owner’s Manual
PLACEMENT (Continued)
LE-1 PLACEMENT
In a normal installation, the ULTIMA LE-1 receives its signals
from the preamplifier’s main output jacks and sends its signals (via
an internal crossover) to the ULTIMA SUB-15. To use the shortest
interconnect cables, place the ULTIMA LE-1 near the amplifier.
However, in doing so, please observe the following:
•
To help dissipate internal heat, provide the ULTIMA LE-1
with adequate ventilation. Do not enclose the unit in an
unvented cabinet. Allow a minimum clearance of 4 to 6 inches
above the ULTIMA LE-1 and at least 2 inches on either side
for air flow.
•
Place the ULTIMA LE-1 so its front panel is readily accessible
for viewing and control with the enclosed remote control.
•
Provide convenient access to the ULTIMA LE-1’s rear panel to
allow for easy interconnection and later adjustment of system
controls (see System Optimization on page 25).
NOTE: Be sure to use adequate speaker cables to connect the
ULTIMA LE-1 and SUB-15(s). As an aid in determining the
maximum wire length for any gauge of speaker cable, please see
Figure 9 on page 18.

Owner’s Manual
CONNECTIONS
The ULTIMA SUB-15/LE-1 is designed to be connected together
to form a complete powered subwoofer system. Audio interconnections to your main amplifier or home theater controller can be any
combination of unbalanced or balanced terminations, with full
balanced connections offering the best noise suppression.
Please read the following six applications (starting on page 19) before
proceeding with the actual connections. For clarity, power connections are not shown. Also, be sure to observe the following points:
•
Use high-quality speaker cable with a maximum total loop
resistance (for each wire run) of 0.07 ohms or less. Use the
chart in Figure 9 (on the next page) to determine the maximum
wire gauge.
A high loop resistance will result in improper low-frequency
damping and serious degradation of sound quality. Follow
the cable-gauge recommendations and make sure all connections are tight. Consult your Revel dealer as to specific recommendations for your application.
IMPORTANT
•
Turn off all audio system power before making any connections.
•
Read the owner’s manuals that were included with your audio
components to confirm their connection procedures.
•
Verify correct polarities (i.e., + to + and - to -) when making
connections, as shown in Figures 10 through 15 starting on
page 19. Failure to do so will cause poor imaging and diminished bass response.

CONNECTIONS (Continued)
SUB-15/LE-1 WITHOUT HIGH-PASS CROSSOVER
Revel recommends using both a low-pass and high-pass crossover
with any “main” left and right loudspeakers. The FM-2 module is
designed to be transparent when inserted in the main signal path.
The use of a high-pass crossover greatly reduces distortion, increases
dynamic range, and optimizes the transition from the ULTIMA
SUB-15 to the main loudspeakers. Your Revel dealer can help with
the proper FM-2 settings.
If the ULTIMA SUB-15/LE-1 will be used without a high-pass
crossover (see Figure 13), contact your Revel dealer for help in
setting the FM-2 low-pass crossover so the main speakers and the
ULTIMA SUB-15(s) will produce an optimum combined response.

SYSTEM OPTIMIZATION
After connecting the ULTIMA SUB-15/LE-1, perform Basic
System Optimization at the listening position. When finished, read
Optimizing Performance with a Test CD, Room Gain Compensation,
and Boundary Compensation (on the next three pages) to see if your
application requires further optimization.
NOTES: The ULTIMA LE-1 is shipped with the CROSSOVER
switch in the ENABLED position, allowing the audio signal to pass
through the internal FM-2 crossover. In a multi-channel system (see
Figure 11 on page 20), be sure to set controller outputs to full range
L/R and no SUB. If applicable, set all other channels (i.e., center, side,
and rear surrounds) to pass 80 Hz and above. Below 80 Hz, signals
will route to the ULTIMA SUB-15.
If you intend to use the subwoofer output from a multi-channel controller, you must bypass the ULTIMA LE-1’s internal FM-2 crossover
(see Figure 12 on page 21).
BASIC SYSTEM OPTIMIZATION
1. Set all volume controls to minimum positions and all tone
controls to flat. Turn on the audio system power. The ULTIMA
LE-1’s display will remain off for 5 seconds during a self-diagnosis test. Upon completion, the display will show one dash
indicating Auto Music Sensor is on, or three horizontal dashes
indicating this feature has been bypassed. Either display indicates that the ULTIMA LE-1 is in standby mode. See
Automatic Music Sensor on page 28 for additional details.
2. Using pink noise as a source, increase the main amplifier’s level
controls to a comfortable listening level.
NOTE: Pink noise can be found on audiophile test and demonstration CDs, as well as home-theater controller setup laserdiscs
and DVDs. Do not use the generated noise from a multi-channel
controller, as it is not full-range.
If Automatic Music Sensor is active (see Automatic Music
Sensor on page 28), the ULTIMA LE-1 will turn on. If it is not
active, use either the Triggered Power Control or POWER
switch (on the front panel) to turn on the ULTIMA LE-1.
(See A Note on Power Management on page 29.)
...continued on next page
ULTIMA SUB-15/LE-1 25
Owner’s Manual
SYSTEM OPTIMIZATION
BASIC SYSTEM OPTIMIZATION (Continued)
NOTE: The ULTIMA LE-1 takes approximately 10 seconds to complete its “power-up” sequence. During this time, turning either the
PHASE or LEVEL controls will not change the readings on the front
panel display, nor will any sound emanate from the subwoofer. The
“power-down” sequence also takes several seconds, after which the display indicates either one or three horizontal dashes, depending on
whether Automatic Music Sensor is active or bypassed.
3. Aim the ULTIMA LE-1 Remote Control at the ULTIMA LE-1
and use the VOLUME +/– controls (or use the LEVEL control
on the front panel) to set the bass output from the ULTIMA
SUB-15. Try to smoothly blend its sound with the pink noise
coming from the main speakers.
NOTE: The ULTIMA LE-1 display will indicate the level in dB.
4. Listen to a wide-range of program material to further fine-tune
the subwoofer level. Adjust the remote’s PHASE +/– controls
(or use the front panel’s PHASE control) to optimize the bass
response. There is no right or wrong setting – only what sounds
best.
NOTE: The ULTIMA LE-1 display indicates the phase in degrees
and reverts to level display after a period of PHASE control inactivity.
OPTIMIZING PERFORMANCE WITH A TEST CD
If you have access to a CD, DVD, or laserdisc with special test signals, you can more accurately optimize the subwoofer’s phase adjustment. The correct setting will be most easily heard by temporarily
reversing the + and – connections to the ULTIMA SUB-15 (or to
all ULTIMA SUB-15s, if more than one is present in the system).
1. Locate a source that is either a band of pink noise centered at or
near 80 Hz, or a warble tone or sine wave near 80 Hz.
2. Turn off all system power and reverse the + and – connections
to the ULTIMA SUB-15(s).
3. Turn on all system power and play the selected test signal.
While sitting at the prime listening position, adjust the PHASE
+/– controls (on the ULTIMA LE-1 Remote Control) until you
hear minimum bass (because the subwoofer connections have
temporarily been reversed).
26 ULTIMA SUB-15/LE-1
Owner’s Manual
4. After making the adjustment, note the phase reading on the
ULTIMA LE-1’s LED display. (Don’t forget that after a period
of inactivity, the readout switches from phase to level.) Then,
turn off all system power.
IMPORTANT
5. Switch the + and – connections on the ULTIMA SUB-15(s)
to their original, in-phase connections.
6. Turn on all system power.
ROOM GAIN COMPENSATION
At very low frequencies, most listening rooms exhibit a rising
response known as Room Gain, as shown in Figure 16. While
many audiophiles find this effect desirable, we’ve included a Room
Gain Compensation circuit in the LE-1 that can be used to compensate for this gain to achieve ultimate accuracy in most rooms.
When activated, it will equalize the low bass frequencies for a flatter response and will also significantly increase the dynamic range
capability of the ULTIMA SUB-15(s), while reducing distortion.
To activate (or defeat) Room Gain Compensation:

Room Gain Compensation is on. Room Gain Compensation may
also be turned on and off by pressing the FREQ EQ IN/OUT
switch, located on the rear panel (see Figure 7 on page 14).
2. Listen to a variety of sources and alternately press the FREQ

ULTIMA SUB-15/LE-1 27
Owner’s Manual
AUTOMATIC MUSIC SENSOR
The ULTIMA LE-1 is equipped with a power management system
called Automatic Music Sensor. In the default mode, internal
circuits continually sense the inputs for presence of audio signals.
When detected, the ULTIMA LE-1’s power supply will be automatically turned on. When audio signals are absent for approximately 25
minutes, the Automatic Music Sensor instructs the power supply to
revert to the standby mode to conserve power. You can control the
Automatic Music Sensor by performing the steps below:
1. On the ULTIMA LE-1 front panel, press POWER to apply full
power to the unit. Wait approximately 10 seconds for the LE-1
to switch into its full operating mode.
2. On the ULTIMA LE-1 rear panel (refer to Figure 7 on page
14), locate the MUSIC SENSOR BYPASS switch.
3. Press and hold the switch for at least 5 seconds to bypass (or
enable) Automatic Music Sensor. When the ULTIMA LE-1 is
in standby mode, the front panel LED display will indicate
three horizontal dashes when Automatic Music Sensor is
bypassed, and one dash when it is enabled.
NOTE: In this mode, when this feature is bypassed, you can use the
front panel POWER control to turn the ULTIMA LE-1 on and off,
or use trigger control (see “Triggered Power Control” on page 29, or
also see “Front Panel Layout” on page 13). The ULTIMA LE-1 will
remember bypass (or enable) settings each time it is turned on (i.e.,
each repetition of Step 3 will cause Automatic Music Sensor mode to
alternate between enabled and bypassed).
28 ULTIMA SUB-15/LE-1
Owner’s Manual
TRIGGERED POWER CONTROL
Another method for turning the ULTIMA LE-1 on and off is by
means of the POWER TRIGGER IN jack, located on the FM-2
module (see Rear Panel Layout on page 14). When a dc voltage of
between 4 and 15 volts is supplied to this 1⁄ 8" mini jack (tip is
positive), the ULTIMA LE-1 will turn on and remain on until the
trigger voltage is removed.
More reliable than music sensing, trigger control is frequently
available in integrated audio-video systems.
A NOTE ON POWER MANAGEMENT…..
Power can be controlled by the trigger feature or Automatic Music
Sensor, but not by both simultaneously. If you insert a plug into
the POWER TRIGGER IN jack, be sure to disable the Automatic
Music Sensor. Still, you can always use the front panel POWER
switch to turn the ULTIMA LE-1 on or off, regardless of what
automatic control feature is in use. The POWER switch will
always override the active power control feature in use.
For example, when Automatic Music Sensor is active, pressing the
POWER switch will turn on the ULTIMA LE-1 even though the
music may be at such a low level that the automatic circuits are not
activated. (For signal levels below threshold, the ULTIMA LE-1 is
kept in the Standby mode, to eliminate its turning on due to transient signals or stray noise impulses.) If the POWER switch is
pressed off and Automatic Music Sensor is active, the ULTIMA
LE-1 will enter Standby mode and turn power back on if an audio
signal of sufficient level is present at its inputs.
If triggered power control is being used, the front panel switch will
turn the ULTIMA LE-1 on or off, regardless of the presence or
absence of a trigger signal. The ULTIMA LE-1 will re-synchronize
with the trigger signal after the trigger signal sequences through
on-off or off-on states, accordingly.
ULTIMA SUB-15/LE-1 29
Owner’s Manual
LOW FREQUENCY GAIN SWITCH
The ULTIMA LE-1 incorporates a gain range adjustment that
assures optimum operation with a wide variety of associated electronics and other conditions. This 3-position jumper system is set
at the factory to +36 dB and usually does not require adjustment.
If, after performing System Optimization (starting on page 25), you
feel the audio system requires additional (or lower) low frequency
gain, perform the steps below to add (or subtract) another 6 dB:
1. Turn off all audio system power.
2. On the ULTIMA LE-1 rear panel (see Figure 7 on page 14),
locate the FM-2 Filter Module, and remove the thumbscrews.
3. Gripping the two handles on the module, pull the FM-2 out
of the chassis.
4. On the module, locate the gain range jumper, S5, and move it
to the desired setting, as shown in Figure 17. Note that at the
highest gain setting, the jumper is simply “stored,” rather than
being used to make an electrical connection.
5. Reinsert the FM-2 Filter Module and firmly press it in. Tighten
the thumbscrews.
6. Turn on all audio system power.

LOW FREQUENCY LIMITER SETTING
The ULTIMA LE-1 incorporates a limiter circuit on the FM-2
Filter Module to reduce possible sudden and unexpected low
frequency effects that could overdrive an ULTIMA LE-1 and its
connected ULTIMA SUB-15(s).
Unlike conventional subwoofer protection circuits, the ULTIMA
LE-1 limiter circuit has no effect whatsoever until signal conditions
are such that the amplifier would otherwise “clip.” The circuit
includes two settings whose selection is dependent on whether the
ULTIMA LE-1 is connected to one or two subwoofers.
The factory setting is one (1) subwoofer. To change it to two (2)
subwoofers, perform the steps as described in the previous section,
except in step 4 locate the limiter jumper, S6, and move it to the
desired setting.
WARNING
The S6 jumper MUST be set to either position for the ULTIMA
LE-1 to work properly; if it is removed completely, the maximum output level will be limited to a very low level.
ULTIMA SUB-15/LE-1 31
Owner’s Manual
CROSSOVER FREQUENCY AND
SLOPE SELECTION
The FM-2 Filter Module also features adjustments for frequencies
below which the subwoofer is the predominant source and above
which the other speakers in the system “take over.” The adjustments, labeled LOW PASS FREQUENCY and HIGH PASS
FREQUENCY respectively (see Figure 7 on page 14), are set at
the factory to 80 Hz, the frequency most commonly used in
multi-channel audio systems. Different values for high or low
crossover frequencies may be more appropriate in a given system.
Your Revel dealer can assist you in selecting the optimum highand low-pass crossover settings.
Moreover, the FM-2 Filter Module can accommodate the use of
different front-channel speakers with an appropriate selection a
high-pass filter slope of 12 dB per octave (two poles) or 24 dB per
octave (four poles). This setting should only be changed if the
front speakers are changed. Either your dealer or, in the case of
non-Revel front speakers, the speaker manufacturer should be
consulted for the proper setting of these adjustments. To change
the crossover slope setting, perform the steps below:
1. Turn off all audio system power.
2. On the ULTIMA LE-1 rear panel (see Figure 7 on page 14),
locate the FM-2 Filter Module, and remove the thumbscrews.
3. Gripping the two handles on the module, pull the FM-2 out
of the chassis.
4. On the module, find the four small, black removable jumpers
at positions S1, S2, S3, and S4 (see Figure 17 on page 30). For
12 dB per octave slope (the default setting), the jumpers
should be positioned so that they bridge the two pins closer to
the row of 40 connectors (along the rear edge of the FM-2
board). For 24 dB per octave slope, move the jumpers so that
they bridge the two pins closer to the panel at the front of the
FM-2 board.
NOTE: All four headers must be in the same position; either closer
to the rear or the front of the board.
5. Reinsert the FM-2 Filter Module and firmly press it in. Tighten
the thumbscrews.

Owner’s Manual
CABINET CARE
The ULTIMA SUB-15 subwoofer cabinet has a paint finish and
does not require any routine maintenance. Use a soft cloth, dampened with water only, to remove any fingerprints or to wipe off dust.
Clean the grille by gentle vacuuming, or use a lint remover or twosided tape. For wood side panels, occasionally use a household furniture polish to maintain the beauty of the hardwood veneers. For aluminum side panels, use a soft cloth, dampened with soapy water
only, and wipe them in the same direction as the grain.
AMPLIFIER CARE
The ULTIMA LE-1 does not require any routine maintenance. If
desired, use a soft cloth to remove any fingerprints or to wipe off dust.
IMPORTANT
Do not use any liquids to clean the ULTIMA LE-1’s finish.
TROUBLESHOOTING
If the ULTIMA SUB-15/LE-1 sounds distorted, stops playing, or
otherwise seems to be malfunctioning, first determine whether the
problem is in the subwoofer, the wiring, and/or other audio components. If the problem also affects the main speakers, the cause is most
likely in your electronics. If it is only noticed in the subwoofer, make
sure that all connecting cables are correct and in proper working
condition. Make sure the subwoofer is plugged in and turned on.
If the front panel LED display shows an error code, use the chart
(on the next page) to determine the probable cause and solution.
NOTE: An error code will be briefly displayed each time the unit is
turned on or off, by any means. This is normal and is not a fault.
If the ULTIMA LE-1 does not respond to commands from the
ULTIMA LE-1 Remote Control, try replacing the two AAA batteries
(located in compartment on backside) with new ones.
If everything seems to be in good working order and the subwoofer
still malfunctions, contact your Revel dealer for assistance (see
Obtaining Service on page 35).
WARNING
Do not attempt to repair the ULTIMA SUB-15/LE-1 yourself.

OBTAINING SERVICE
We take great pride in our dealers. Experience, dedication, and
integrity make these professionals ideally suited to assist with our
customers’ service needs.
If your Revel component requires service, please contact your dealer.
Your dealer will then decide whether the problem can be remedied
locally, or whether to contact Revel for further service information or
parts, or to obtain a Return Authorization. If needed, call the Revel
Customer Service Department at:
1-818-830-8777 on any business day, from 9 A.M. to 5 P.M. PST.
The Revel Customer Service Department works closely with your
dealer to solve your service needs expediently.
IMPORTANT
Return Authorization must be obtained through your dealer
BEFORE a unit is shipped for service.
It is extremely important that information about a problem be
explicit and complete. A specific, comprehensive description of the
problem helps your dealer and the Revel Customer Service
Department locate and repair the difficulty as quickly as possible.
A copy of the original bill of sale will serve to verify warranty status.
Please include it with the component when it is brought in for
warranty service.
WARNING
All returned units must be properly packaged in their original
packing material, and the proper return authorization numbers
must be marked on the outer carton for identification. If the
packaging to protect the unit is, in our opinion or that of our
dealer, inadequate to protect the unit, we reserve the right to
repackage it for return shipment at the owner’s expense. Neither
Revel nor your dealer can be responsible for shipping damage
due to improper (i.e., non-original) packaging.
Your dealer can order a new set of shipping materials for you if you
need to ship your component and no longer have the original
materials, or if they are in poor condition. There will be a charge
for this service. We strongly recommend saving all packing materials in case you need to ship your unit some day.
