Your New Speedwoofer 10SMKII
The original RSL Speedwoofer 10S was introduced in 2016. Since that me, it has racked up
numerous awards, including several product of the year tles. It set a standard for what’s
possible from a compact, aordable 10 inch subwoofer. Its patented Compression Guide
tuning allowed it to outperform sealed subwoofer designs when it came to accuracy and it
also matched the bass impact usually associated with larger 12 inch ported subwoofers.
Your new RSL Speedwoofer 10SMKII elevates performance even further. Its all-new amplier
design has increased power output at 400W RMS. Built-in DSP (digital signal processing) allows
beer usage of the available power to further increase frequency response and output. The
Speedwoofer 10SMKII digs deeper in the bass with usable response that extends down to 20
Hz. With DSP, you can now choose between 2 sound modes. One mode duplicates the sound
characteriscs of the original Speedwoofer 10S. The other mode extends the bass even fur-
ther to increase the impact from movies.
The Speedwoofer’s rugged, cast-frame woofer has been improved to handle the increased
power of the amplier. In addion, the Speedwoofer’s exclusive Compression Guide tuning
has been revised. This along with a new rear vent further reduces any potenal port noise or
chu.
When it comes to bass, quality is as important as quanty. It’s easy to produce an inexpensive
subwoofer that produces gobs of low end. However, geng it to do it cleanly is a lot more
dicult. Many aordable subwoofers sound sloppy and localize, which means they draw
aenon to themselves. The bass they produce seems separate from the rest of the sound.
You can sense that bass is coming from the locaon of the subwoofer. With a properly de-
signed subwoofer, bass should sound as if it is coming from its actual locaon in the sound
track. With the new Speedwoofer 10SMKII, precision and accuracy is maintained.
Before You Dig In!
We know the temptaon is great to tear into the carton, unpack you new sub and re it up. If
that urge seems overwhelming, then go right ahead. It’s unlikely that you’ll hurt anything.
However, subwoofers do need a bit of ne tuning in order to experience their full capabilies.
The goal of this thrilling, acon-packed owner’s manual is to help you enjoy the full perfor-
mance of your new Speedwoofer.
Many of you (and us as well) don’t like having to suer through owners manuals. Most
manuals try to answer all quesons, except the one you may have. We’ve tried to make this
manual as easy to read as possible and even helpful at mes. However, if you already have
enough knowledge about subwoofers and you know not to do the dumb things warned about
in the safety pages, be our guest and start enjoying your Speedwoofer 10SMKII.
Since we don’t know about your parcular audio setup, whether it’s home theater or stereo,
we’ve tried to cover all the bases. So feel free to skip around and only read what’s of interest.
Compression Guide Technology - A Lile History
Part of the Speedwoofer 10SMKII’s accurate bass response is due to our exclusive Compres-
sion Guide Technology. A number of years ago, we noced that almost all speakers (including
early RSLs) suered from a problem. It was an awareness that the sound of bass over
speakers was quite dierent from bass at a live performance. When you’d hear bass live, you
would hear various details in the bass as well as feel the impact.
5

Compression Guide Technology - History - Connued
For example, with a bass guitar, you can hear the pick of the string along with the bass note.
With a kick drum, you could hear the rap of the mallet against the skin of the drum and your
body could feel the impact. However, with convenonal speakers, all you’d hear was an ill-
dened boom. Back then, the only speakers that seemed to get it right were the big, bulky and
expensive transmission-line systems.
We needed to know why there was a disparity between live bass and that reproduced by
speakers. Aer some research, it became apparent that the problem was due to the way the
woofer was tuned in the enclosure. As was the case then just as it is now, two tuning methods
were used by most speaker companies. In one case the cabinet was completely sealed. This
method is called acousc suspension or air suspension. In the other method, the cabinet had
a calculated opening called a vent or port. The length, width and height of the port was de-
signed to reinforce bass at the lowest frequencies.
The problem with both of these methods is that they rely on system resonance to properly
load the woofer. System resonance acts like a spring in that once a note stops, the woofer
cone wants to connue vibrang. This results in what we call woofer overhang and results in
muddy bass. Aer realizing the problem, we spent years aempng to lessen the eects of
system resonance. Eventually, we found the soluon and the results were spectacular. We call
it Compression Guide and it was a method of dividing the insides of the speaker enclosure into
areas of compression and expansion. As the sound wave passed through these areas, the
eects of resonance were greatly reduced.
We discovered that Compression Guide also paid huge dividends in the midrange as well.
Bookshelf speakers tuned by Compression Guide exhibited much cleaner and transparent
sound with both vocals and music. In comparison, other bookshelf speakers sounded “boxy”.
It also helped the speakers to image more accurately.

Speedwoofer 10 SMKII Features
• Improved Compression Guide Technology Tuning with rear venng.
• Precision 10” woofer with heavy, die-cast aluminum frame, massive magnet structure and
motor assembly. This allows the cone, along with its surround to achieve high excursions,
delivering deep, powerful bass with complete control and linearity.
• Powerful 400 Wa RMS Digital Amplier. This ecient amplier minimizes power con-
sumpon (around 1 wa in standby mode, only slightly higher in operaon mode with no
signal). Because amplier standards are not strictly enforced, many manufacturers would
rate this amplier at a much higher waage. If this amplier were rated in peak power (a
specicaon we don’t agree with) it could be rated in excess of 1,000 was.
• New integrated DSP maximizes output at all frequencies extends the frequency response
for deeper bass. Two sound modes are available.
• Dense MDF wooden cabinet with internal bracing. Unlike most subwoofers, the Speed-
woofer 10S’s enclosure is completely lled with damping material to further reduce un-
wanted resonances.
• Wireless capability. The Speedwoofer 10S has a wireless receiver built in. If you are unable
to run an audio cable to the subwoofer, you can purchase our oponal wireless transmier
and get full performance wirelessly.
First Steps
• Be careful when using sharp objects to open boxes. The inseron of a long and/or sharp
object such as a blade can damage the components inside. Use of chainsaws, machetes,
power tools, explosives, light sabers, and most kitchenware is not recommended. If in
doubt, ask mommy to help you.
• Please take a moment to inspect your subwoofer for damage. If you nd any damage that
you did not specically request, please contact us or the shipping company immediately
and take photos of the box and subwoofer. All components have been inspected when
leaving our factory; however damage can occur during shipping.
• If possible, we recommend saving all packaging, including boxes, as a convenient means of
re-packaging for moving or for sending your subwoofer in for service (in the unlikely event
it needs it).
• You will need either an RCA cable or the oponal wireless transmier to connect the sub-
woofer. If you purchase an RCA cable, you do not need to buy an expensive one. Subwoof-
ers reproduce a narrow band of frequencies, typically 20-200 Hz. Do not allow some slick ,
fast-talking, know-it-all salesperson to convince you to spend a lot on this cable. Just pur-
chase a cable that is well-constructed and has good shielding to reduce interference.

More Than You Probably Want to Know About Room
Acouscs
The acouscal characteriscs of your listening room has a major eect on sound quality. This
is so important, it bears repeang (so feel free to re-read the rst sentence). If your room has
good acouscal qualies, even mediocre speakers can sound prey good. In turn, if your room
has poor acouscs, high-end speakers can sound lacking. Acouscal qualies are determined
by the dimensions of your room and the amount of sound-absorbing materials present.
Because this manual covers the installaon of your new subwoofer, we will concern ourselves
with how your room’s acouscs aect bass. Bass distribuon is strictly determined by a
room’s dimensions. A room with evenly distributed bass will deliver the same volume of bass
in dierent seang posions. Obviously, you can’t do a heck of a lot about the dimensions of
your room. Don’t worry; few rooms are close to perfect. You can however maximize the
evenness of bass distribuon by properly posioning your subwoofer (if you have that
exibility) and or using mulple subwoofers.
While virtually all of today’s Audio/Video receivers and processors include microphones and
room correcon circuitry that can help to smooth bass frequency response, they will not
correct for bass distribuon problems.
Posioning Your Subwoofer
The posion of the Speedwoofer in your room has a tremendous eect on the results it
provides. There is a wealth of informaon online in forums and review sites regarding
subwoofer placement. If you have the exibility to place your Speedwoofer in dierent
posions, we suggest doing some experimentaon to determine the best spot. The goal is to
get an even volume of bass in your various listening posions. Here is some basic and by no
means complete informaon about subwoofer posioning.
• Bass distribuon in a parcular room is determined by the dimensions of the room. Every
room has locaons of peaks (where bass is increased) and nulls (where bass is substanally
decreased). If your seang posion is in a peak, the amount of bass can be reduced
through equalizaon. However, if your seang posion is in a null, bass cannot be
signicantly increased (aempng to do so wastes power).
• Placing a subwoofer near a wall will increase the volume of bass. Always allow a few inches
between the wall and your subwoofer. This is necessary for airow to the amplier and for
airow emanang from the rear port or vent.
• Placing a subwoofer in a corner will further increase its output.
Here is an example of one method commonly used to determine subwoofer posion. Connect
your subwoofer and temporarily place it in your listening posion (on the sofa, etc.). Then,
while playing some music with a constant bass track, crawl around the perimeter of your room
and nd the spot where the bass seems to have the best quality and quanty (don’t let
anybody see you, otherwise you’ll have some explaining to do). Then, place the subwoofer in
the spot where you heard the best bass. You can repeat this for dierent listening posions
and see if you can nd the best subwoofer posion that accommodates the most listening
posions.

Mulple Subwoofers
The majority of our customers are quite happy with the performance of a single Speedwoofer.
However, many audio experts recommend dual subwoofers. They feel that with two or more
subs it’s much easier to get consistent bass distribuon by placing the two subs in dierent
posions. Mulple subs also deliver more powerful bass throughout the room.
If you want foundaon-cracking levels of bass, dual subwoofers can achieve a up to a 6db gain
in bass output. While that may not seem like a lot, for an amplier to deliver 3db more
volume, its power must double! If you place dual subwoofers near each other, you’ll get
approximately a 6db gain in bass volume. That’s huge!
Some of the many ways of posioning mulple subwoofers include:
• Subwoofers next to or on top of each other.
• Subwoofers in each corner.
• Combinaon of subwoofers in corners and midpoints along the wall.
As in the above secon on posioning, there is a lot of informaon online and we highly
encourage experimentaon to nd the best posions for your Speedwoofers.
Home Theater Installaon
We have designed the Speedwoofer 10S to accommodate both home theater as well as stereo
systems. The most common installaon with be with an A/V receiver or processor. In this case,
all you’ll need is a single RCA cable and a wall outlet. The RCA cable does not have to be
expensive as the subwoofer only reproduces a narrow band of frequencies. However choose a
cable that is well-shielded and constructed to last.
Connect one end of the RCA cable to your receiver or processor’s subwoofer (or LFE) output.
Connect the other end to the Speedwoofer’s LFE input. Then, set the Speedwoofer’s internal
crossover to bypass by rotang the crossover frequency knob fully counter-clockwise unl it
clicks and points to the LFE mode. You will not be using the Speedwoofer’s internal crossover,
because that funcon is performed by your A/V receiver or processor. It will also set the DSP
to the LFE mode (more about this in the secon about DSP sengs).

The Easiest Stereo Installaon Secon You Will Find!
(In this manual) (If you are a home theater user, please skip to page 12)
The RSL Speedwoofer 10SMKII can be used in virtually all stereo systems. Depending on your
equipment, there are dierent opons for hooking up your Speedwoofer.
If Your Stereo Receiver Or Amplier Has Pre-amplier
Outputs
Method #1 - Connecon Though The Speedwoofer 10S
This method, requires 2 pairs of RCA cables. One pair of cables is connected from your
preamplier (or receiver’s pre-amplier) outputs to the Speedwoofer’s le and right line
inputs. Then another pair is connected from the sub’s le and right line outputs to your power
amplier (or back into your receiver’s power amplier inputs). The audio signal travels from
your pre-amplier through the subwoofer giving the subwoofer the audio it needs and then
back out to your power amplier and to your speakers. In this method, the Speedwoofer’s
internal crossover is used to control the bass of the subwoofer. To use, set the crossover
frequency control to the desired crossover frequency. This also selects the DSP’s music mode
(more about this in the secon about DSP sengs).
Method #2 - Connecon Using Y Adapters
In this method, you also will need two pairs of RCA cables, however the lengths on one may be
shorter. You will also need two Y Adapters that split the audio into two RCA connecons.
Connect a Y adapter to le pre-amplier output and the other Y adapter to the right
pre-amplier output. Then connect one pair of cables from the le and right pre-amplier
outputs to the Speedwoofer’s le and right line inputs. The other pair of cables connect from
the le and right pre-amplier’s outputs to the power amplier’s le and right inputs. Please
see the diagram above. As in the rst method, the Speedwoofer’s internal crossover is used to
control the bass reproducon of the subwoofer. Set the crossover frequency control to the
desired crossover frequency. This also selects the DSP’s music mode (more about this in the
secon about DSP sengs). 10

Receivers And Ampliers With No Pre-amplier Outputs
Method #3 - Connecon Using Speaker Wires
If your equipment can’t accommodate the rst two methods, use this method. You will need
an addional pair of two-conductor speaker wires. In addion to your main speaker
connecons, you’ll run a second set of wires to your subwoofer (see diagram above). As in
the above methods, you’ll use the Speedwoofer’s internal crossover. Set the crossover
frequency control to the desired crossover frequency. This also selects the DSP’s music
mode (more about this in the secon about DSP sengs). In the unlikely event you
encounter hum or noise, please see the soluon explained in the troubleshoong secon of
this manual.
In a normal home theater system, the A/V receiver or processor protects the other speakers in
the system by ltering o the bass when you set the crossover frequencies. This is especially
important when your other speakers are smaller and not designed to handle low-bass
frequencies. In the above three methods of connecng your subwoofer in a stereo system,
your amplier will deliver all of the bass to your other speakers. If the speakers are small,
damage could result if played at a very loud volume. However, you can protect your smaller
speakers by using external inline lters to reduce the bass frequencies going to your speakers.
These lters plug inline with your RCA cables. If you would like us to recommend the correct
lters for your system, please contact us. Please note that you can only use this soluon with
methods #1 and #2. If you need to use method #3 and are concerned about protecng your
smaller speakers, please also contact us.

The oponal RSL AT4 wireless transmier lets you send audio wirelessly to a receiver built-in to
the Speedwoofer 10SMKII. A wireless connecon can be handy when it’s dicult to run an RCA
cable to your subwoofer.
Another benet is that it makes it easy to experiment placing your Speedwoofer in dierent
listening posions.
The RSL AT4 Wireless Audio Transmier has a range up to 50 . The rst me you setup the
AT4 for wireless use, you will need to pair it with the Speedwoofer. You should only need to do
this once.
Wireless Transmier Pairing Instrucons
1. Plug the Speedwoofer in to a wall outlet and turn on the power.
2. Connect the AT4 to an output from your A/V receiver, processor, integrated amplier, or
pre-amplier. Use either the included mono or stereo RCA cable.
3. Connect the transmier to a USB power source. Please use the included USB wall adapter
or an independent power source. If you use your Audio/Video receiver or other A/V
component as a USB power source you may experience interference.
4. The light on the transmier will ash slowly. Push and hold the transmier’s pairing buon
unl it ashes rapidly and then release the buon.
5. Immediately while it is ashing rapidly, press and hold the pairing buon on the
Speedwoofer for 3-4 seconds and release it. Do not hold the pairing buon any longer
than 4seconds. The transmier light should display solid blue.
6. Your Speedwoofer is now paired.
7. If the transmier light begins to ash slowly, repeat the above procedure. If pairing sll
fails, temporarily place the AT4 transmier closer to the Speedwoofer and away from
other Wi-Fi devices. The transmier does not need an audio connecon in order to pair it.
Please Note: Solid objects such as walls, cabinet doors, etc. can block the wireless signal. Its
signal can also be aected by interference from wireless networks, large objects and other
electronic devices.

Wireless Connecon Informaon (Important)
If you are using your RSL Speedwoofer 10SMKII wirelessly, here is some addional informaon
you should know:
• When pairing the wireless transmier to the Speedwoofer, the Speedwoofer’s pairing
buon must be held for 3 or 4 seconds and no longer.
• Holding the Speedwoofer’s pairing 6 seconds or longer will temporarily unpair the
Speedwoofer. This can be useful if you wish to change to a wired connecon. When the
Speedwoofer is temporarily unpaired, you will be able to use an RCA cable instead of
sending the signal wirelessly. However, it is important to note that if the Speedwoofer is
unplugged from an AC outlet or its power switch is turned o, the Speedwoofer will resort
to its wireless connecon. To avoid this, leave the wireless transmier’s power cable
disconnected or use an in line power switch to turn o the transmier when not in use.
• Using the Speedwoofer wirelessly will result in it always staying in operaon mode. This is
OK, because in operaon mode with no signal applied, power consumpon is only slightly
higher than in standby mode. This has no eect on the longevity of the Speedwoofer’s
amplier. However, if you wish to have the Speedwoofer go into standby mode, you can
unplug the power to the transmier when not in use or install an inexpensive inline power
switch to turn it o.
• If you wish your Speedwoofer to be permanently unpaired to your transmier, it can be
paired to a dierent transmier. Then, it will forget the rst transmier. Or, you can just
not power on your transmier and the Speedwoofer will always use a wired connecon.
There are three ways to connect dual subwoofers. Many of today’s A/V receivers and proces-
sors provide two subwoofer or LFE connecons. With these, you can run separate RCA cables
to each of your subwoofers. If your A/V receiver only has one subwoofer jack, you can connect
two RCA cables to a Y adapter and one cable to each subwoofer. The third way is to connect
the rst subwoofer normally and connect an RCA cable from the rst subwoofer’s line outputs
to the second subwoofer’s line inputs (see diagram above). In a home theater installaon you
will bypass both subwoofers’ internal crossovers. For stereo installaons you’ll use and adjust
both subwoofers’ internal crossovers.
For connecng two subs wirelessly, you can pair both subs to a single transmier. Note:

Some Installaon Tips
(Tips are always appreciated)
Most modern A/V receivers and processors include some type of auto setup and room
correcon. During the setup process, they will ask you to adjust the volume control on the
subwoofer to a certain volume. In most situaons, you do not have to follow this instrucon
exactly. Your goal should be to have the subwoofer’s volume control as close to the vercal or
12 O’clock posion as possible. This will give you the most exibility to adjust the subwoofer’s
output up or down depending on what you’re listening to. Most A/V receivers also allow you
to adjust the subwoofer’s volume by their remote.

The goal of a properly setup subwoofer is to produce accurate, controlled bass without
sacricing the teeth chaering impact some enjoy. The most common mistake people make is
seng the subwoofer to play too loudly. The subwoofer should always blend seamlessly with
your other speakers rather than being intrusive.
Your RSL Speedwoofer 10SMKII is powered by a conservavely-rated 400 wa RMS amplier.
Combined with its Compression Guide tuning, your Speedwoofer should be more than capable
of providing an abundance of clean, powerful bass. In addion, the RSL Speedwoofer 10SMKII
contains circuitry that helps prevent distoron when played at excessively loud volumes.
However, all subwoofers can be played loudly enough to be overdriven regardless of size,
power, or price resulng in audible clipping (a form of distoron). In the unlikely event that
you desire more bass, try placing the RSL Speedwoofer in a corner.
The RSL Speedwoofer 10SMKII has high quality, built-in protecon circuitry, although no
protecon circuitry is foolproof. It’s best to prevent the subwoofer from being over-driven in
the rst place. Here are a couple of indicaons of trouble to watch out for. If you noce the
following taking place, reduce your subwoofer’s volume unl these symptoms disappear.
• Noise that doesn’t sound natural. In movie scenes or music with heavy bass, listen for any
noise that doesn’t sound like it should be there. In some cases this can sound like a raling
or a very muddy rumble.
• Clipping. A good indicaon of clipping is if your subwoofer sounds excessively sloppy; as if
it is opping back and forth. This will produce some prey ugly sounds. The RSL
Speedwoofer 10SMKII uses high quality protecon designed to keep clipping to a
minimum.
If you’re not sure if your subwoofer is being overdriven, remove the grill and look at the woof-
er itself. See if it appears as if it’s moving back-and-forth excessively. The woofer should
always move with ght, controlled precision. If you suspect the woofer’s movement is
excessive, try reducing your subwoofer’s volume unl it appears to move appropriately.

A Discussion About Maximum Bass Output
When it comes to movies, the latest digital recording formats allow movie producers to
incorporate an enormous amount of bass into their soundtracks. As a maer of fact, some
movies produce bass that is more intense than larger-sized home theater subwoofers can
handle. That is why virtually all modern subwoofers contain circuits that protect the
subwoofer and its amplier by liming the maximum power that can be produced.
The amount of bass your system can produce is determined by several factors. For some, the
bass produced by a single quality subwoofer like our Speedwoofer 10SMKII is more than
plenty. Many of our customers report that they can’t turn up their subwoofer nearly all the
way without upseng other members of their family. However for some, any amount of bass
is never enough. It isn’t our posion to dictate how much bass is appropriate.
Another important factor is posioning. Depending on the posion of the subwoofer, there
will be peaks (where bass is more intense) and nulls (where bass is diminished). If you posion
the subwoofer so your listening posion is in a null, you will not get adequate bass regardless
of the size of your subwoofer or its volume seng. So, if you have the exibility, spend some
me determining the best posion for your subwoofer.
If you have a very large listening room or simply desire more bass capability, we recommend
considering a second subwoofer. This can add 6db of increased bass output, which is huge.
This will allow both subwoofers to operate more eciently with increased headroom for those
explosive bass moments in movies.
Care And Maintenance
• Clean your subwoofer using a so, moist cloth (Windex or water is recommended),
preferably microber or lint-free cloth. Do not put your subwoofer in the washing ma-
chine.
• Be very gentle when cleaning the front of your subwoofer, trying not to put pressure on
the woofer itself.
• Be careful with liquids or beverages near your Speedwoofer. It does not play beer when
wet. Don’t place owers or plants that require watering on top of the subwoofer. Watering
your Speedwoofer will not make it grow.
• Please keep your Speedwoofer away from direct sunlight and heat sources.
• If you operate the subwoofer with the grille o, please make sure that the woofer does
not come in contact with anything as it can be damaged.
• Wires can loosen over me. Periodically make sure all connecons to the Speedwoofer are
ght. If a wire loosens and touches other wires, your system could be damaged.
• Do not expose your subwoofer to extremely hot or cold temperatures.
• Your Speedwoofer may not be used as a otaon device.

Operang your RSL Speedwoofer 10SMKII
Power Indicator - When the indicator light is red, the Speedwoofer is in standby mode (when
the auto power switch is set to on). When the Speedwoofer receives a signal, it will turn on
and the light will change to green. If the light won’t change to green, check the audio
connecon to the subwoofer (either the RCA connecon or the wireless pairing light on the
oponal wireless transmier). Please make sure your receiver’s output volume to the
subwoofer is adjusted high enough to trigger the auto on funcon. If the light isn't on at all,
then the subwoofer isn't receiving power. Re-check the power switch, and AC power
connecon. Finally, check the fuse (see page 17).
Wireless Pairing Switch - To use your Speedwoofer wirelessly, you'll need to turn on the
Speedwoofer and the transmier. If the transmier shows a solid light, it is paired and ready.
If the light on the transmier is ashing, it requires pairing. Please refer to the pairing
procedure on page 14. Keep in mind that wireless operaon can be aected by distance,
objects or interference from your home’s Wi-Fi network.
Volume - Controls the volume of bass output. During inial setup with your A/V receiver, we
recommend that you set the volume control somewhere around the 12 o'clock posion. That
will allow maximum exibility if you need to perform ne adjustments with the volume control
at a later me. If you nd that you have to turn the volume control up too high or down too
low, refer to the setup in your A/V receiver to adjust the output volume to the subwoofer.

Crossover-DSP Sengs – The crossover knob selects both the crossover frequency and also lets you
select from two DSP sound modes. If the knob is turned fully counterclockwise unl it clicks (LFE
enabled), the internal crossover of the Speedwoofer is bypassed and the crossover funcon will be
handled by your home theater receiver or processor. Also, with the Speedwoofer’s
crossover bypassed, the DSP mode will extend the Speedwoofer’s bass response, which can be ideal
for movies.
If the knob is rotated clockwise o the bypass posion, the Speedwoofer’s crossover is acve, and
you can select the appropriate frequency. For example, an 80Hz seng means your Speedwoofer
will handle all frequencies at 80Hz and below. An 80Hz seng is recommended for larger
bookshelf speakers. For smaller bookshelf speakers, we recommend a seng of 90-100Hz. We also
suggest trying dierent crossover sengs so that the Speedwoofer integrates seamlessly with the
rest of your system.
When the internal crossover is acve, the DSP will enable your Speedwoofer to deliver the same
performance as our original Speedwoofer 10S. This may be a good choice if you primarily listen to
music or if you wish to limit the bass that is transmied to other rooms. To use this mode with your
home theater receiver’s internal crossover also acve, turn the crossover knob fully
clockwise. This will prevent the Speedwoofer’s crossover from interfering with your home theater
receiver’s crossover.
Phase - Allows you to align the bass through subwoofer so it blends perfectly with the rest of the
speakers. In addion, the phase should be adjusted so that the output in your room is
maximum at the crossover frequency. If you’re a bit techy, this can be determined using a sound
level meter or a sound meter smartphone applicaon and a pure tone that corresponds to the
crossover frequency. The standard seng is 0 degrees, but some experimentaon may be
needed.
Line In/LFE In - LFE stands for low frequency eects. This is where the Speedwoofer receives the
bass signal from your receiver or amplier. For home theater, use a single RCA cable from the
receiver's subwoofer or LFE output to the Speedwoofer's LFE in. For a two channel stereo system,
use a stereo pair of RCA cables to the Speedwoofer's Line inputs.
Line Out - For a two channel system, this feeds the signal back to the amplier for your other
speakers. The Line Outs can also be used to connect an addional Speedwoofer. See the Dual
Speedwoofer secon.
Speaker Level In - This connecon can be used in stereo systems with ampliers that do not have
pre-amplier outputs. Please refer to the instrucons at the top of page 13. Do not use this
connecon if you’ve already connected the Speedwoofer using any of the other methods.
Ground - In the unlikely event there is hum or noise when using the speaker level in connecons,
the ground connecon can be used to ground the Speedwoofer to your other components. Please
see the secon on ground loop hum or noise on the next page.
Input Voltage - Fuse - Is Normally set for use in the U.S. and Canada at 115 Volts. If your country's
voltage is 230-240 Volts, you must change this seng before using the Speedwoofer. You must
also change the fuse to a 2.5 amp fuse. The fuse locaon is just below the AC receptacle on the
back of the subwoofer. Unfortunately, failure to do this will void your warranty.
Main Power Switch - Auto Power Switch - The power switch will normally be le on. When
switched on, and the auto/on switch is set to on, your Speedwoofer will go into standby mode (red
light) unl it receives an audio signal and then it will turn green. With no signal, it will return to
standby mode aer approximately 20 minutes. When the auto power switch is set to o, the
Speedwoofer will always stay in operaon mode (but consumes very lile power, even at this
seng). When connecng and disconnecng cables to the Speedwoofer, make sure the main power
switch is o.

Troubleshoong (For any issue you may call or email us. We’ll be happy to help)
No Sound from Your subwoofer. Power indicator not lit.
1. Check to conrm that your subwoofer’s power switch is set to the “on” posion and that the
power cord has not been damaged and is securely plugged into the wall outlet. Verify that the wall
outlet is powered.
2. Check the RSL Speedwoofer 10SMKII’s removable fuse. It is located below the AC socket on the
amplier.
Accessing the fuse. Make sure the Speedwoofer is unplugged from the AC.
To access the fuse, insert a at-head screwdriver in the horizontal slot located on the power cord
socket, just below where the cord plugs in. Gently pry the fuse housing open unl it
detaches. Extract the housing from the power cord socket, remove the fuse and inspect it. If the
wire inside the cylinder is severed, displays a gap or looks burned, the fuse is bad and needs to be
replaced. Replace with the a fuse of exactly the same value. The value is indicated below the
power socket. If the new fuse blows, your subwoofer requires service. Please contact us.
The Speedwoofer has internal circuit protecon that could be tripped. If you suspect this, turn
down the subwoofer’s volume and turn o the power. Wait 5 minutes before turning it on.
Ground loop hum or noise.
Although a seldom occurrence, this can happen when speaker level inputs are used. It’s not the
fault of the subwoofer, but is caused by dierences in the ground characteriscs between
dierent audio equipment. Fortunately, this is easy to x. There are two methods. Connect a piece
of wire from your audio amplier’s ground to the subwoofer amplier’s chassis. If your audio
amplier does not have a ground lug, then loosen a screw around the perimeter of the chassis.
Wrap the stripped end of the wire around the screw and re-ghten. Then, connect the other end
to the amplier’s ground screw. The hum should vanish.
As an alternave, if your amplier has an unused RCA input, you can connect a single RCA
cable to either the le or right jack and the other end to the subwoofer’s RCA line out jack. This
eecvely connects the grounds of the two units together eliminang the hum.
Subwoofer will not go into standby mode.
Make sure the auto power switch is set to on. If you are using the wireless transmier, the
Speedwoofer will always stay in operaon mode. This is normal. In this mode, the Speedwoofer’s
power consumpon is only slightly higher than in standby and the longevity of your Speedwoofer
will not be aected. For more informaon please see wireless informaon on page 13.
If you are using a wired connecon and the Speedwoofer stays in operaon mode, it is because
there is noise in either your AC or audio lines. Somemes this noise will not be audible, but will be
enough to keep the Speedwoofer in operaon mode. Again, the power consumpon is only
slightly higher and the longevity will not be aected.
