directly to the red(+) and black(-) input jacks on the back of
the enclosure (see diag. 1 ).
0 +
-~- --~ -- . ~ . .. ............ .. ·- . -+
an each - Since the loudspeakers have a rated
impedance of an each, more than one speaker
may usually be wired to one amplifier channel (see
·· diag. 2). (See "amplifier impedance load" below.)

Integrating the Subwoofer SB-2- Treat each input
of the Subwoofer as an an loudspeaker and wire into
a complete system accordingly (see diag. 3). (See
"amplifier impedance load" below.)

Amplifier Impedance Load - When you connect more than one loudspeaker system to an amplifier channel, either by
twisting two wires together at the speaker location or via individual"home runs" from the speakers to the amplifier, the load
impedance to the amplifier drops. To find the maximum number of an speakers that can be wired in parallel to each
channel of your power amplifier, divide a by the amplifier's minimum impedance load recommendation (e.g. an Control®
speaker ...;- 4n amp's minimum impedance = 2 speakers per channel, see diags. 2& 3).

Series/Parallel - It is possible to utilize various series/parallel'hook-up' topologies to increase the number of loudspeaker$ ----~--
driven on an amplifier. See diag. 4 for one example of a series/parallel hook-up topology. . _J_
Note: Mis-matching the speaker impedance such that it is below the minimum impedance rating of an amplifier channel can
damage the amplifier and degrade performance. If the application requires more than 2 speakers per amplifier channel ---+-
wired in parallel, a distributed line system should be considered. Also check your amplifier's manual for cautions and
recommendations.
Importance of Correct Polarity ("In-Phase/Out-of-Phase")- When two loudspeakers are wired with opposite polarity
("out-of-phase") relative to each other, the low frequencies of the loudspeakers cancel each other, even though the speak-
ers are "working hard." Trying to correct the lack of bass with an equalizer can damage your loudspeakers-- equalization
cannot correct polarity errors . Always make sure multiple speakers are connected in proper polarity . (See "Poor Low
Frequency Output" in the Troubleshooting section for instructions about how to detect and correct polarity problems.)

I •Incident/Reflected/Absorbed • JBL Control ® Contractor series speakers
-.l-- are designed as fixed installation loudspeaker systems for use in a variety of
environments. Performance may nevertheless vary from room to room
because of differences in the acoustical setting. Since an enclosed room
-+
presents acoustical boundaries (walls , floors & ceilings), sound indoors
exhibits quite complex behavior. Each time a sound wave strikes a boundary ,
· -· 7 part of the wave's energy is reflected and part is absorbed (see diag . 1 ).
Reflection & absorption are dependent on the frequency of the sound wave
··· -+ and the angle at which it strikes the boundary.

• Absorption - When designing your system, note that
. people and furniture absorb sound, while glass and tile
reflect sound . The percentage of energy that a boundary
absorbs is often expressed by an absorption coefficient of
the boundary material, where an absorption coeffic i ent of
1 =complete absorption and O=perfect reflective surface (see
diag. 2) .
ON EL OUD SPEAK ER MULnPLE QU I ET SPEAK ERS
• Reverberation - Reverberation is the reflected sound
waves continuing to bounce between the boundaries , losing
energy with each reflection. When sound strikes the reflec-
tive boundaries of a room , after a time the room is filled with
random reflected sound waves . Music and speech become
unintelligible (see diag. 3A). To minimize reverberation in a
highly reverberant room, it is advisable to install more
speakers, and play them at lower levels (see diag . 38) .

• Boundary Loading - This is a good trick for increasing bass
without taxing the amplifier. It is also possible to make a system
sound too "muddy", so use caution. If you move the speaker from
open space to a wall , bass notes will increase by + 3d B. If you
move it to a2 boundary corner, another t3dB ... and another t3dB
for a three boundary corner! (see diag. 4).
VERTICAL
• High Frequency Coverage - High
frequencies go where you point them .
Simply aim the center axis of the
speaker into the plane slightly above
the listening area. The go ox 90 °
horns of the Control ® Contractor
Series disperse the high notes by 45 °
off axis in every direction. For large or
unusually shaped rooms, divide the
area into zones and let the horn
patterns dictate the spacing between
the speakers (see diag . 5).

TYPICAL "HOME RUN" CONFIGURATION
• Daisy Chaining- It is most common, easiest, and cheapest
to run wires from the amp to a speaker, then from that
speaker to another (see diag. 6A).
•Home Runs - If you desire true stereo L&R from each
listening position, "home runs" are best, from the amplifier
directly to each speaker (see diag. 68).

• Wind - Wind gives the illusion that a sound is coming from
a different direction than it really is. This creates a resultant
propagation vector (see diag. 1 ). When sound propagates
with the wind it tends to refract downward, and against the
wind refract upwards (see diag. 2), (*refraction is the term
used to describe the bending of sound) .

•Temperature- Temperature differences also have a small
effect on sound propagation. Hot air is less dense than cold.
Sound travels faster in a less dense medium and therefore
speeds up as air gets warmer, and slows down as air gets
cooler. The result is the refraction of sound. For example this
may manifest itself as sound propagates over a cool body of
water on a hot day. The sound will tend to "bounce" along
the surface of the lake and travel a lot further than the
Inverse Square Law may dictate (see diags. 3& 4).
SOUND OUTDOORS
From the speakers to our ears - Since you usually want a target
background SPL of about 70dB - 80dB to your listeners, keep in
mind the Inverse Square Law, which states that in a free field with no
walls, floor, or ceiling, the intensity of sound decreases with the
square of the distance. For example when you double the distance
between the speaker and your listener's ear, the SPL decreases by
6dB (i.e. If a speaker's output is 1 OOdB SPLat 10 feet away, at 20
feet away the SPL is decreased to 94dB.) Don't forget, a1 OdB drop
will sound "half as loud".

It is important to understand that just as the propagation of sound
outdoors is effected by its surroundings so is the propagation of sound
indoors. Some of these environmental factors exist in both cases,
such as reflective surfaces and absorbant materials, but there are a
few unique effects that may need to be considered. The factors
described on this page can cause the behavior of an outdoor installa-
tion to deviate from the Inverse Square Law . Remember not all
frequencies of the propagated sound will be affected uniformly.

HOT AIR

DESERT
• Humidity- Because water vapor is lighter than air, humid air .
is less dense than dry air and, therefore absorbs less
acoustical energy than dry air particularly at frequencies
above 2kHz. To labour the point, a speaker mounted on a
tree in a jungle will project high frequency sound further than
the same speaker mounted on a cactus in the desert (see
diags. 5& 6).
Painting the Speakers-
The polystyrene speaker enclosures of the Control® 23,
Control® 25, & Control® 28 can be painted to match almost
any decor. The vinyl skin of the Control® SB-2 subwoofer can
also be painted.
• Remove the grilles. Mask the woofers, tweeters, & ports on
the front, and the wire terminals on the back, being careful
that no tape comes in direct contact with the drivers.
• Clean the enclosures with a light solvent such as mineral
spirits by rubbing the components with a lightly dampened
cloth. Do not, however, use abrasives such as sandpaper or
steel wool on the enclosures. Nor should you use gasoline,
kerosene, acetone, MEK , paint thinner, harsh detergents or
other chemicals. Use of these cleaners may result in perma-
nent damage to the enclosures.
• After cleaning, apply two or more thin coats of either latex or
oil-based paints. Latex paints will adhere better if an oil-
based primer is used first. Application can be by rolling,
brushing, or spraying.
•The grilles require masking of the logo plug, then spray
painting. If the grill is rolled or brush painted, the mesh may
become clogged with paint , and poor sound quality may
result.
• The /nvisiBalfM mount may also be painted, but because it
is metal, latex paints will not adhere as well as other finishes .

.. i
+
Your Control Contractor system has been designed and manufactured for durability and reliable service. As with any fine
product, proper maintenance and care will extend the life of your system.
You can expect your system components to perform indefinitely if you use them within their stated limits for power handling,
and see that they are not abused.
Always protect the loudspeakers from over-excursion caused by strong subsonic signals (signals below 30Hz). If your
--r- -· amplifier has a "low cut" or "high pass" switch, engage it.
+- Please note that although the C23, C25 and C28 are designed to be weather resistant they are NOT WEATHERPROOF.
I Insect screens have been included in the design of the low frequency vents. It may be wise to periodically check and clear
--+--- any debris collected, to ensure proper operation of the vent.

It is not unheard of for rodents to eat and destroy foam. It is recommended that the foam surrounding the SB-2 subwoofer
enclosure be treated flith a rodent repellent, especially in an installation that may be subject to the occasional rodent
visitation.

such as crackling.
3. Constant noise such as
buzzing, hissing , or
the humming sound.
4. Poor low frequency
output.

Action
• Replace the cable(s) con n ec t ing the loudspeaker system
and amplifier .
•
Make sure the amplifier channel is being fed an input
signal (preferably via a "signal input" indicator on the
amp).
• Check that the amplifier channel's volume control is
turned up.

• Connect the speaker and cable which had no output to i
another amplifier channel, making sure an i np ut signal is ---~-
fed to the new amp channel. If you then get output, the l
problem was the amplifier channel. If not , then the ----r---
problem may be in the cable or speaker.
• Check all cabling for proper connector contact since a
bad connection can result in intermittent contact or
dramatically increased resistance which , in turn , can
cause reduced output or noises unrelated to the signal.
• Since loudspeakers cannot generate these sounds by
themselves, you may have a faulty electronic device in
the signal chain.
