Product Features  
The SS2 is a very high performance, innovative subwoofer  
system that provides exceptionally deep, uniform, dynamic  
and low distortion bass reproduction. In addition, it will  
provide near-ideal performance with any room placement  
and when used with any type of main loudspeaker. These  
performance abilities are the result of new (patents pending)  
technology developed to overcome the major problems that  
subwoofers typically exhibit: poor integration with the  
main speakers and altered response due to nearby walls.  
1000 Watt Amplifier  
The SS2 is powered by a Class D, switching-mode 1000  
watt RMS amplifier.  
The amplifier’s very high power ensures that the woofers  
can provide all the output they are capable of without power  
compression or limiting.  
The SS2 can be used as a stand-alone unit, with  
a THIEL passive crossover or with the SmartSub  
Integrator, depending on your requirements. Here  
is a brief description of some of the unusual  
performance features this subwoofer system  
provides.  
Very High Output, Very Low Distortion Woofers  
The SS2 uses two very high output, very low  
distortion 10" drivers that utilize aluminum  
diaphragms, heavy cast chassis and THIELs short coil/  
long gap, copper stabilized motor systems powered by  
10 lb magnets in structures with a total weight of 20 lbs.  
The short coil/long gap design results in very low  
distortion levels that are only one-tenth that of typical  
drivers with the same excursion rating. This magnet  
system’s very long magnetic gap, along with the very high  
excursion suspension, allows each driver to move a very large  
amount of air (65 in3) – as much as many 15" woofers. By  
using two of these drivers the SS2 can effortlessly reproduce  
even demanding sources at high volume levels.  
SS2 1000 watt amplifier  
Since switching amplifiers are very high efficiency, about  
92% in this case, very high power and currents can be  
delivered without large heat sinks, fans or additional power  
supply capacity for large amounts of waste heat. This type of  
amplifier is ideal for subwoofer applications since the  
amplifier does not have to deliver significant power at high  
frequencies.  
Placement Correction  
Placement controls  
(patent pending) on the SS2  
match the unit’s  
performance to its  
environment, whether away  
from walls, in a corner or  
anything in-between. These  
controls correct for both  
the general increase in level  
and for the partial  
cancellation of certain  
frequencies caused by a  
nearby wall. By providing  
correction of these effects  
for both the side and rear  
walls, the SS2 can provide  
accurately balanced,  
uniform response with  
virtually any room  
One of two SS2 drivers

Temperature Correction  
Accurate Matching to Main Speakers  
The SS2 electronics contains unique circuitry (patent  
pending) that corrects for compression distortion due to  
heating of the drivers’ voice coils. Without this correction  
subwoofer output levels could decrease by as much as 5 dB  
and the response altered at times of high demand. The  
correction allows the subwoofer to provide more accurate,  
uncompressed and dynamic reproduction.  
Rather than providing generic built-in crossover controls  
that can rarely achieve high quality blending of the  
subwoofer with main speakers, the SmartSub can be used  
when needed with a separate unit, either a dedicated passive  
crossover or the universal SmartSub Integrator.  
The passive crossovers provide perfectly blended  
augmentation of the main speakers, allowing the  
combination to provide very accurate reproduction of the  
entire sonic spectrum, to below the audible range.  
Passive Crossover  
Heat sensor on voice coil  
A thermistor is mounted to the woofer’s voice coil so that  
the amplifier can continuously measure the voice coil’s  
temperature. Knowing this, circuitry automatically adjusts  
both frequency response and level of the signal to accurately  
compensate for all effects of temperature on performance.  
This compensation ensures that the subwoofer’s response  
and sensitivity don’t change with temperature.  
The SmartSub Integrator provides unprecedented ability  
to perfectly match any main speakers and provide total  
system performance that is as well integrated and balanced as  
a full range speaker. This superior performance is achieved by  
innovative circuitry (patents pending) that automatically  
calculates the ideal subwoofer response to perfectly match  
the characteristics of the main speakers. Therefore, instead  
of the usual crossover controls that tell the subwoofer how to  
perform, the SmartSub Integrator has settings for the  
characteristics of the main speakers you are matching, the  
configuration of your system and the performance you  
desire. This information is then used to automatically  
calculate and implement the ideal subwoofer response. In  
addition, the unit enables the total system to operate in  
either augment or crossover system mode and can control up  
to 16 subwoofer units in either mono or stereo configuration.  
Protection from overheating  
An automatic shutdown feature is included that protects  
the drivers from excessive heat produced by input levels that  
are excessively high. By knowing the temperature of the  
voice coil at all times, a shutdown is automatically executed  
if temperatures ever reach levels that could cause damage.  
The unit continues to monitor the temperature and is  
automatically restarted when the temperature falls to a safe  
level.

System Configurations  
The SS2 can be used in four ways depending on your  
requirements:  
If your main speakers play sufficiently loudly for all your  
uses but do not reproduce the full low frequency range of the  
left/right channels, you should also use the subwoofer to  
augment the bass response of your main speakers. This can  
be accomplished without altering the signal or wiring to your  
main speakers by using one of the next two configurations.  
1. As a stand-alone unit.  
2. With a passive crossover.  
3. With the SmartSub Integrator in augment mode.  
4. With the SmartSub Integrator in crossover mode.  
The configuration chosen will determine your required  
equipment, hookup connections and processor settings.  
Which system configuration is best for you depends mainly  
on the capabilities of your main left/right speakers.  
2
A SmartSub Passive crossover can be used if one is  
available to match your main THIEL speakers and low  
frequency adjustments are not required.  
Additional discussion of these options can be found in  
the section Crossover Use. In addition, there is a  
comprehensive flow chart for your reference on pages 12 and  
13 that guides you through all aspects of system  
configuration, hookup, and adjustment. More information  
on Integrator hookup and adjustment can be found in that  
product’s manual.  
Passive Crossover Configuration  
This configuration has connections and benefits identical to the  
following one except the passive crossover provides no adjustments  
and is available for only selected THIEL model main speakers.

your uses and they reproduce the bass with satisfying

The SmartSub Integrator in augment configuration  
should be used if a passive crossover is not available  
for your main speakers, you desire adjustability of the main  
channel bass level or extension, or if you desire more than  
one subwoofer in your system, or two stereo subwoofers.  
4
If your main speakers do not play sufficiently loudly  
due to bass overloading, then the Integrator should  
be used in crossover mode to allow the transfer of low  
frequency energy from the main speakers and into the  
subwoofer.  
Integrator Augment Configuration  
Integrator Crossover Configuration  
In this configuration the subwoofer is used to reproduce both the  
subwoofer channel and the deep bass portion of the left and right  
channels and achieves near-perfect blending of the main channel  
bass with the main speakers.  
Connecting the SmartSub Integrator between the processor and the  
main speaker power amp allows the Integrator to be used in  
crossover mode so that bass can be kept from the main speakers  
and reproduced by the subwoofer instead. This usually allows the  
main speakers to play more loudly than otherwise so that the bass  
range and the output of the system are enhanced.  
Tell the processor the main speakers are large, even if they are not.  
This configuration can be ideal if the main speakers play loudly  
enough. Its also perfect for audio systems where the subwoofer is  
used to extend the bass range.  
Tell the processor the main speakers are large, even if they are not.

Crossover Use  
Do you require a crossover?  
Processor Bass Management  
Without a crossover the subwoofer will provide very high  
quality reproduction of the Low Frequency Effects (LFE), or  
“point 1”, channel of a multi channel sound system.  
Surround sound processors have the ability to redirect  
the bass energy away from your main speakers and into the  
subwoofer channel where it is reproduced by the subwoofer,  
with the benefits of allowing the main speakers to play  
louder than they otherwise would, and the bass to be  
reproduced better. This is implemented by telling the  
processor that your main speakers are “small”.  
When used with a crossover, the subwoofer can, in  
addition, also reproduce the low frequency part of the left  
and right channels in a 2 channel or multi channel music or  
video sound system. It is desirable to use the subwoofer in  
this capacity if the main speakers do not reproduce the  
entire bass range or if the main speakers cannot play at the  
volume level desired without distortion. Depending on your  
requirements, the crossover can be either the bass  
The limitation of this bass management approach is the  
poor balance and integration between the subwoofer and the  
main speakers that the processor’s generic filters provide. It  
may be suitable for low standard video systems and will  
seldom be suitable for music.  
management capabilities of a sound processor, one of our  
dedicated passive crossovers, or the SmartSub Integrator.  
Here is a description of each of these with their advantages.  
THIEL Passive Crossovers  
There are several passive crossovers available that match  
a THIEL subwoofer to various THIEL speaker models.  
Since they are designed for specific models, they achieve very  
good integration and balance between the subwoofer and the  
main speakers. Also, being passive, they are of quite  
reasonable cost. They allow the subwoofer to augment the  
main speakers in the precise way that will enable the  
combination of main speaker and subwoofer to produce  
perfectly balanced and blended sound with the bass range  
extended to below 20 Hz. Two passive crossovers can be  
used with two subwoofers to provide stereo bass  
reproduction.

A limitation is that these crossovers do not redirect bass  
energy away from the main speakers and so the main  
speakers will not play any louder than otherwise.  
This is often an ideal system for music systems and a  
good approach for video systems when the main speakers  
play sufficiently loud but do not have extended, deep bass  
response.  
THIEL SmartSub Integrator  
The SmartSub Integrator provides a high level of  
flexibility, universality, and functionality. It provides near-  
perfect integration with any main speakers, regardless of  
brand. It can be used both in augment mode, where the  
subwoofer extends the bass range of the main speakers, and  
in crossover mode. In crossover mode the built-in high pass  
filter transfers bass energy away from the main speakers and  
redirects it to the subwoofer, so that the main speakers are  
able to play louder. The Integrator also allows adjustment of  
crossover frequency, LFE level and separate adjustment of  
main channel bass extension and low frequency level. In  
addition, it can control stereo subwoofers, and be used to  
control systems with up to 16 subwoofers.  
This is a complete, no-compromise approach with no  
limitations.

Higher output is achieved when the subwoofer is placed  
near a wall and even more output is available when placed  
near a corner of the room. If very high output is desired in  
large rooms corner placement can be used with little trade-  
off in sound quality. For use in very large rooms, greater than  
4,000 ft3, more than one SS2 may be required if very high  
playback levels are desired.

Subwoofer Placement  
If the subwoofer is used only for LFE reproduction, it  
can be placed almost anywhere. If more than one subwoofer  
is used, placing them in different locations tends to even out  
possible room resonance irregularities.  
If the subwoofer is used with a crossover or Integrator to  
reproduce the low frequency portion of the main channels  
then placement is a little more important. The subwoofer(s)  
preferably should be approximately the same distance from  
the main listening area as the main speakers. With one  
subwoofer the best position is usually somewhere between  
the main speakers but behind them a few feet if possible in  
order to maintain good stereo imaging.  
The use of two subwoofers allows the low frequency  
signal to be processed in stereo by the crossover unit, and,  
therefore to provide the best possible imaging. In this case,  
it is preferable that the subwoofers be placed somewhat near  
each main speaker. Good placement is anywhere from  
between the speakers, near each speaker, or at the side walls.  
Dual corner placement provides maximum output from each sub,  
higher total output, good imagingand more even room response.  
For LFE (point 1) channel use, corner placement is often ideal,  
providing maximum output.  
Dual subs near the main speakers provide the higher output of dual  
subs combined with the best imagingand most even room  
response.  
Center placement against the front wall is often optimum for music or  
movie systems where the subwoofer is used to reproduce left/right  
channel bass. It provides high output and good imaging.  
Dual subs at the side walls provide the higher output of dual subs,  
high output from each sub, good imagingand even room response.

Setting up the Subwoofer  
Hookup  
If the subwoofer is being used with a passive crossover or  
SmartSub Integrator, a balanced XLR interconnect cable is  
connected from the unit’s subwoofer output to the  
subwoofer’s Normal Input. If more than one subwoofer is  
used, they are “daisy-chained” by connecting an additional  
XLR interconnect cable from the Normal Output connector  
of the first subwoofer to the Normal Input of the next  
subwoofer.  
The placement settings should be adjusted to correspond  
to the placement of the subwoofer. Set the Side Wall Distance  
to the distance from the side of the subwoofer to the side  
wall and the Rear Wall Distance to the distance from the rear  
of the subwoofer to the rear wall. The distance is displayed  
in meters, which is the distance in feet divided by 3.3. If a  
distance is greater than 2.5 meters (or 8 feet) set the control  
to maximum (OFF). If the subwoofer is placed in a cabinet  
the settings should correspond to the room wall distances,  
not the distances to internal cabinet walls. If the subwoofer  
is recessed into the wall so the front is flush with the wall,  
then the rear control should be set to -0.5.  
If the Integrator is not being used, then an RCA  
interconnect cable is connected from the processor’s  
subwoofer output jack to the subwoofer’s LFE Input. If more  
than one subwoofer is used, an additional cable is connected  
from the LFE Output connector of the first subwoofer to the  
LFE Input of the next subwoofer.  
The subwoofer’s power cord must be plugged into an AC  
outlet and the power switch turned to the “on” position.  
If the norm/auto switch is turned to the “On” position  
the subwoofer is always on, ready to reproduce a signal. If the  
switch is set to the Auto” position, the subwoofer’s amplifier  
will automatically turn on when it detects a signal to  
reproduce and stay on for approximately 1/2 hour after a  
signal.  
Setting the Surround Processor  
Tell the processor that you have a subwoofer.  
If you are using a Passive Crossover or the Integrator  
then the surround processor should be set to deliver the left/  
right channel bass to the main speaker channels by telling it  
that the main speakers are full-range (even if they are not).  
The unit is equipped with a control input that will turn  
the unit on when a DC voltage between 5 and 25 volts is  
applied, if the Auto/On switch is set to the Auto” position.  
If you are not using a Passive Crossover or Integrator and  
the main speakers are not able to reproduce deep bass, you  
can tell the processor that the front speakers are “small” so  
that the main channel bass is redirected to the subwoofer.  
Pilot light  
The pilot light on the back panel and the front of the  
subwoofer glows green during normal operation. This green  
light can be turned off if you desire by pressing both the  
increase and decrease buttons simultaneously when the  
numeric display is not on. The light can be turned back on in  
the same way.  
If you are using the Integrator set the subwoofer channel  
level in the processor to the same level as the left and right  
channels and use the Integrator to adjust the LFE level. If  
you are not using the Integrator use the processor’s  
subwoofer level setting to adjust the LFE level.  
Auto shutdown  
Control Settings  
The subwoofer is equipped with an automatic shutdown  
feature that will turn off the output of the subwoofer if the  
drivers, amplifier or rear panel get too hot or if the line  
voltage is too low. This can occur if a very high input level  
lasts too long or if the subwoofer has insufficient ventilation.  
If the automatic shutdown is activated, subwoofer output  
will be interrupted and the light on the input panel will flash.  
The unit will resume operation when conditions return to  
safe levels. Here is a list of the light flash modes and the  
conditions they indicate.  
There are three adjustments which are made by using the  
three buttons below the numeric readout. Use the Select  
button to select which adjustment will be active, indicated by  
which light is lighted. The setting of the active adjustment is  
displayed in the readout for 10 seconds after any of the  
buttons is pressed. Adjust the active setting by using the  
Increase and Decrease buttons.

level must be adjusted to achieve the proper balance with the  
other speakers. It is usually more convenient to adjust the  
subwoofer level with the processor’s subwoofer level control,  
and in this case a good starting point for the level setting is  
90. If the system’s processor cannot control subwoofer level,  
then the subwoofer’s level adjustment is used. The level can  
be adjusted “by ear” to achieve a pleasing balance so that the  
low frequency sound effects are not too weak or too strong.

If the unit shuts down often, this indicates that you  
should improve its ventilation, turn down the system’s  
volume control, turn down the subwoofer’s level control or  
add an additional subwoofer.

Feet  
The subwoofer is supplied with four pointed, screw-in  
dents in hardwood floors. They are screwed into the bottom  
of the unit, and should be individually adjusted until the unit  
is firmly seated onto the floor without rocking. Then tighten  
each of the back-nuts to lock the feet in place.

various colors and patterns when heat  
or line voltage is a problem.
