Using subwoofers and satellite loudspeakers with a pre-engineered passive crossover built into the 
subwoofer can be a very effective way of achieving high-fidelity sound economically for applications 
requiring greater bandwidth than is typically possible from full-range speakers alone.   
When applied properly, small subwoofer-satellite systems – often referred to as “sub-sat” systems –  
can provide high fidelity sound for a wide variety of applications, such as restaurants, retail stores, 
hotels, music cafes, leisure venues, sports bars & lounges, fitness centers, themed applications, and 
many more.
This guide provides recommended subwoofer-satellite configurations that work well together.    In 
addition, the Connection Information and System Design sections provide important information 
for applying these subwoofer-satellite systems properly.

Important Satellite Connection Information 
For Mono (& 70V Mono) Systems
For Mono systems, always connect half the satellite speakers to one of the sa\
tellite speaker output terminals and the other half to the 
other satellite speaker output terminals.   Do NOT connect to only one of the sets of satellite output terminals .  
In order to avoid excessively low impedance loads to the power amp when using 4 satellite speakers (which could cause the power 
amplifier to fail), the satellite output terminals of the SB-210 in m\
ono mode are connected in series with each other.  This requires 
that speakers be connected to both sets of satellite output terminals, a\
nd that the load on each satellite output be matched.  
Otherwise, there will be very little or no sound coming from the satellite speakers


CORRECT
For systems with 2 satellite speakers, put 1 on each set

The exact configuration of a subwoofer/satellite loudspeaker system depends on a number of factors, such\
 as:• How large the room is and how many satellite speakers it will take to cover the room?   
•  Whether the distance between the satellite speakers allows a single subwoofer to cover the entire space?   
•  Whether the program material is light background music or dominant driving music?   
•  Where the subwoofer will be located in relation to room boundaries (wall, ceiling, corners)?  
The system recommendations in this guide and the performance figures are based on some baseline assumptions which will not be 
correct for all applications.  Adjustments may need to be made.  A discussion of the considerations, bas\
eline assumptions conditions and 
possible adjustment requirements is below.
Sub-Sat System Design
General Objectives
Sensitivity Balance
The volume balance between the subwoofer and the satellite 
speakers in a passively crossed-over system is called sensitivity 
balance. 
   Targets:
a)  Sensitivity  Balance –  Typically,  the  way  the  human 
hearing system works, the subwoofer needs to be 2 to 6 
dB  louder  than  the  satellite  speakers  in  order  to  sound 
balanced.        The  subwoofer/satellite  systems  in  this 
guide  are  all  structured  to  provide  the  proper  range  of 
sensitivity  balance  with  the  subwoofer  located  on  a  flat 
surface (wall, ceiling, floor).  The sensitivity balance can 
be  altered,  as  required,  via  an  active  graphic  equalizer. 
The balance can also be altered by placing the subwoofer 
closer to more boundary surfaces -- see the “Subwoofer 
Location”  section  below  for  more  about  the  effect  of 
positioning.
b)  Maximum  Sound  Level  Balance –  It  is  desirable  for 
the subwoofer to be able to deliver adequate maximum 
sound  output  capability  to  keep  up  with  the  satellite 
speakers  when  they  are  driven  at  their  maximum  drive 
level.    The  subwoofer  output  of  these  systems  is  high 
enough  to  keep  up  with  the  satellite  speakers  at  high 
drive levels. 
Subwoofer Model Selection
All  the  systems  in  this  guide  use  the  Control  SB-210  subwoofer, 
with the exception of the CCS6000 System, which uses the Control 
SB-2  subwoofer.    Passive  crossover  networks  are  built-into  SB-2 
and  available  for  SB-210,  making  it  easy  to  structure  subwoofer-
satellite systems.   
Designing for Other JBL Subwoofer Models
Other  subwoofers  from  JBL  Professional  include  Control  19CS 
In-Ceiling Subwoofer and Control 312CS High Power In-Ceiling 
Subwoofer.    These  subwoofers  are  intended  to  be  used  in  actively 
crossed-over systems -- either contains a built-in passive crossover 
network.   
For determining the proper number of Control 19CS subwoofers, 
use the Subwoofer Utility in the DSD Distributed System Design 
software  (free  download  located  on  the  Software  Download  page 
from the www.jblpro.com website).   
For The Control 312CS subwoofer, use the “Control 300 Subwoofer 
Ratio  Guide”  posted  in  the  Control  300  section  of  the Technical 
Library page on www.jblpro.com website.

Sub-Sat Design Considerations
Sound Level Capability
For each system in this guide, the Max SPL figure is listed, 
describing the continuous sound level that the system can 
maintain on a full-range basis with either speech or music 
program content, with 10 dB headroom for clear transient 
peaks.    
For any installation, the satellite speakers might be located 
next to each other and cover exactly the same area, resulting 
in 6 dB of coupling between them, or they might be located 
far apart and have no overlap between then resulting in no 
coupling.    The Max SPL figures listed in the charts assume 
somewhere in between, that there is some degree of overlap 
in coverage but not full overlap. Therefore, a coupling figure 
of 3 dB is utilized.   
Actual Max SPL 
For applications where there is very little overlap of satellite 
speakers, the actual Maximum SPL will be 3 dB lower for 
2 satellite speakers (and 6 dB lower for 4 satellite speaker) 
than what is listed.  For applications where there is almost 
full overlap (satellite speakers covering the same area), the 
actual Maximum SPL will be 3 dB higher for 2 satellite 
speakers (and 6 dB higher for 4 satellite speakers).
Subwoofer Location’s Affect on Sensitivity  
and Maximum SPL
The system performance figures listed are based on the 
subwoofer being located away from boundary junctions 
and corners.    For applications where the subwoofer will be 
placed at a 2-surface boundary junction (wall/floor, wall/
ceiling, wall/wall), both the Sensitivity and the Maximum 
SPL of the subwoofer increases by 6 dB.    For applications 
where the subwoofer is placed as a corner junction (wall/
wall/ceiling or wall/wall/floor), the Sensitivity and the 
Maximum SPL of the subwoofer increases by 12 dB.  
This can unbalance the subwoofer satellite sensitivity 
balance.  It is a good idea to have an equalizer in the sound 
system to be able to adjust the bass level for proper balance.  
A parametric EQ allows for the best adjustment.  For 
graphic EQ, a minimum of 15 bands is usually required to 
be able to set the EQ break point at the proper frequency.  
Using the MTC-210-SAT Input Module
ALL these systems (except the CCS6000 System that utilizes 
a SB-2 subwoofer) utilize the MTC-210-SAT input module 
installed in the back of the Control SB-210 subwoofer.   
This module provides a full passive crossover consisting 
of a high-pass to the satellite speakers and low-pass to the 
subwoofer drivers.  
4 Ohm / 8 Ohm Setting  
(ie, Satellite Speaker Impedance Selector)  
The module contains a header adjustment for setting the crossover 
to work properly with either 4 ohm or 8 ohm satellite loads per 
output.
Mono / Stereo Setting  
The module also contains a header to set the system to operate 
either as a mono system with a single input (+ and -) wired to 
the Left/Mono input terminals, or as a full stereo system with 
Left input wired to Left input terminals and right input wired to 
Right input terminals.  
     
Figure 1 
Setting Mono/Stereo and Satellite Impedance Headers 
on MTC-210-SAT (and MTC-210T-SAT) Input Module
Mono/Stereo and 4/8 Ohm selection is accomplished by 
moving the headers on the MTC-210-SAT Input Module before 
installing the module into the subwoofer.  Yellow indicators move 
with the headers, annunciating the selected modes visibly on the 
back panel of the subwoofer after the module is installed. Header 
positions shown in the picture above are set to Mono with 4 
ohms per channel of satellite speakers.  Moving the headers in the 
position of the red arrows changes the settings to Stereo with 8 
ohms per channel of satellite speakers.
Operation from a 70V/100V Distributed  
Speaker Line
A different SB-210 input module needs to be purchased for 
operating a subwoofer satellite system via 70V/100V.  It is model 
MTC-210T-SAT, which includes input 70V/100V transformers 
as well as the built-in crossover network.  
Speaker Type for 70V/100V Systems  
Satellite speakers remain LOW-IMPEDANCE (non-T) 
models.   DO NOT use T-version satellite speakers for any 
of the satellite speakers, even those systems operated from a 
70V/100V distributed speaker line.  
45 
						

							
Adjusting Volume of 70V/100V System
Adjust the tap setting to change the amount of power that 
gets to the entire sub/sat system. 
Multiple Systems 
Multiple sub-sat systems can be utilized on a single 
70V/100V distributed speaker line.  Each can cover a 
different area with full-range sound.  Systems can be mixed 
on a 70V/100V line as long as all the systems utilized the 
MTC-210T-SAT module.   See Figure 2.
Subwoofer Distance Consideration
Even though it’s not easy for the human ear to tell where the 
sound  from  a  subwoofer  is  coming  from  (non-localizable), 
that  doesn’t  mean  that  a  single  subwoofer  can  always  cover 
an entire space.   
The  sound  level  from  a  subwoofer  is  louder  nearby  to  the 
subwoofer  and  quieter  farther  away  from  it.    As  rooms 
get  larger  the  level  variation  gets  more  uneven  because  the 
distance from the subwoofer gets longer.   It may be necessary 
to  add  a  second  subwoofer  on  the  other  side  of  the  room.  
Locating  multiple  subwoofers  near  the  center  of  opposite 
walls  within  the  room  often  works  well,  resulting  in  more 
even coverage of the entire room.  
When  greater  subwoofer  output  is  desired,  an  alternative  is 
to  locate  the  subwoofers  near  opposite  corners  of  the  room, 
although the subwoofers can get excessively loud in those corners 
compared to the rest of the room.
For  rooms  where  very  even  subwoofer  coverage  is  desired,  a 
distributed subwoofer system might be a better solution than using 
one  of  the  passive  subwoofer/satellite  systems  from  this  guide.    If 
so,  see  the  subwoofer  chapter  of  the  JBL  guide  entitled Designing 
Better Sounding In-Ceiling Business Music Systems.
Affect of Room Size on Sound Level
The Max SPL figures listed for each system are based on a listening 
distance of approximately 20 feet.   
For  larger  rooms  where  some  listeners  will  be  father  than  20  feet 
from  the  speakers,  the  true  sound  level  capability  of  the  sub-sat 
system  will  be  lower.    For  example,  the  Max  SPL  level  at  40  feet 
-- twice the listening distance -- will be 6 dB lower than the listed 
figure.  
In addition, as the room gets larger, there will be more level variation 
of  the  sound  from  both  the  satellite  speakers  and  the  subwoofer 
from place to place within the room.  This can lead to unacceptably 
high variations in sound level, where the sound might be too loud 
in some areas and too soft in others.  
In  rooms  where  this  is  the  case,  it  may  be  necessary  to  utilize 
more than one subwoofer/satellite system, or to use a more highly 
distributed  system  than  a  small  subwoofer/satellite  system  is 
capable of doing.

Systems with SURFACE-MOUNT (on-wall) 
Satellite Speakers
Application Note:
This combination produces a great full-range sound with flat 
frequency response, usable from 38 Hz to 22 kHz.  
Do NOT use a different quantity or model of satellite 
speaker .
  Changing to a different, higher sensitivity, satellite 
model unbalances the subwoofer/satellite sensitivity balance 
(see “Consideration” notes above), resulting in the mids and 
highs being overly dominant.  Similarly, changing to fewer 
Control 23 speakers results in a different load impedance 
resulting in incorrect crossover point.  This system works 
properly only with 4 pcs Control 23 speakers – they were 
designed to be used together.
System #1:  CCS6000 System
4 pcs Control 23 with Control SB-2
Application
Light volume ambient music in medium size spaces where 
four speakers are needed. 
Max Continuous Average SPL (at 20 feet)

Stereo/Mono Capability
Works best as a stereo system with separate input for left and 
right inputs.
Connection
Connect 2 pcs of Control 23 to each satellite 
output (Left and Right). Do NOT connect all 
4 satellite speakers to a single satellite output.

Ensure  that  the  polarity  hookup  of  the  left  and  right  inputs  is  correct.   If  one  of  the  inputs  is  connected  backwards  (out  of  polarity),  the  sub-woofer will not produce much (if any) bass.

System #2
2 pcs Control 25AV & Control SB-210
Application: Light to medium volume ambient music in 
small to medium sized spaces where two satellite speakers are 
enough to cover the area.   This system produces excellent high 
fidelity sound quality with very strong bass.
Max Continuous Average SPL (at 20 feet): 91 dB (with 
peaks of 101 dB)
Max Output Balance -- The subwoofer has substantially 
higher maximum output capability than the satellite speakers, 
so this system has the capability of optionally being utilized in 
applications where the bass will be EQ’d substantially higher 
than the mids and highs.  The system also works fine for flat-re-
sponse applications.
Lower-Cost Option: Less expensive Control 25 speakers 
can be utilized instead of Control 25AV for a more cost-effec-
tive system.  The system will have slightly lower overall fidelity, 
but will get 1 dB louder.
4 Ohm / 8 Ohm Setting:   8 Ohms
Stereo/Mono Capability: Either setting can be utilized.
Connection:  
Mono Operation – Connect input to the LEFT/MONO 
input terminal.  Put Stereo/Mono header into MONO 
position.  Connect 1 pc of Control 25AV to each satellite 
output (LEFT and RIGHT). Do NOT connect both satel-
lite speakers to a single satellite output.
Stereo Operation – Connect left and right inputs to the 
LEFT and RIGHT input terminals. Put Stereo/Mono 
header into STEREO position.  Connect 1 pc of Control 
25AV to each of the Satellite Outputs (LEFT and RIGHT)
