SPEAKER
PLACEMENT

t is best to establish the locations

I
for the speakers in advance, to

void having to correct errors

a

fter installation has already

a
begun. Refer to these guidelines,

nd also see the owner’s guide for

a

he SS88IWS subwoofer for more

t
information.

It is generally recommended that
you install your SS88IWS in-wall

ubwoofer along the same wall

s
as the front loudspeakers. The

S88IWS subwoofer is not video-

S

hielded and should not be placed

s

ear a video display. Installing the

n
SS88IWS near a corner will tend

o maximize low-frequency output.

t
Be cautious when installing in a
corner, to avoid a “boomy” sound.

lso take into consideration any

A
unusual features of the room, such

s an alcove, which may tend to

a

reate a localized node that may

c
affect bass response in that area

f the room.

o
It is generally recommended that

he speaker be installed so that the

t
bottom of the speaker is approxi-

ately 12" from the floor. Note that

m

nstalling the speaker within the

i
SS88IWSBB back box as shown in
the illustration to the left will
achieve the recommended height.
This is to help with the low-fre­quency loading (bass reinforce­ment). This also helps hide the
speaker in a less visible place.

Remember that these are just
guidelines. Since every listening
room is different, JBL strongly rec­ommends experimenting with the
positioning of your subwoofer prior
to cutting the wall to obtain the
most pleasing results in your room.
One technique that can help you
find the ideal subwoofer location
is to temporarily borrow a stand­alone subwoofer and place it near
the main listening location. Then
move around the room and deter­mine where you hear the most
pleasing bass performance. This
would then be the ideal location
for the subwoofer.

CONNECTIONS

Connection Tips

Refer to page 4 of the SS88IWS sub­woofer owner’s guide for general

nformation on speaker-wire con-

i
nections. This manual includes con­nection guidelines that are specific

o the SS88IWSBB back box.

t
To use the push-type terminals on

he connections panel supplied with

t
the SS88IWSBB back box enclosure,

epress the colored cap until the

d
pass-through hole in the binding
post is revealed. While holding the

ap down, insert the bare end of

c
the wire, or a banana plug, into the
pass-through hole. Release the cap
and tug gently on the wire to ensure
that it is secure.

Since the SS88IWS is a passive
loudspeaker, only speaker-level con­nections are available. Depending
on whether you are using a dedi­cated subwoofer
main receiver/
SS88IWS, select one of the two con­nection methods that follow.

Connection Method #1

Use this method when you are
using the SS88IWS with your main
receiver/amplifier. Connect the main

amplifier or your

amplifier to power the

eft and right speaker-level outputs

l

n your receiver/amplifier to the

o
Input 1 (for left channel) and Input 2

for right channel) connectors on the

(

S88IWS connection panel. Connect

S
the Output 1 terminals to the corre-

ponding terminals on your front left

s
speaker, and the Output 2 terminals
to the corresponding terminals on

our front right speaker.

y
NOTE: When using Connection

ethod #1 with only one SS88IWS,

M
the shorting straps must be
removed.

If you are using two SS88IWS sub-

oofers, connect the left speaker out-

w
puts on your receiver/

amplifier to
Input 1 on one subwoofer’s connec­tions panel, and the right speaker
outputs on your receiver/amplifier to
Input 1 on the second subwoofer’s
connections panel. Then connect
Output 1 from the left­woofer to the inputs

channel sub-

on your main
left speaker, and Output 1 from the
right-channel subwoofer to the
inputs on your main right speaker.
When using the SS88IWS in this
mono mode, you should not remove
the shorting straps.

onnection Method #2

C

se this method when you are

U
using the SS88IWS with a dedicated

ubwoofer amplifier. Connect your

s

ain receiver/

m
subwoofer

nput on your subwoofer amplifier.

i

rocessor’s line-level

p

output to the line-level

Connect the speaker terminals on
your subwoofer amplifier to either

nput 1 or Input 2. If your amplifier

I
has stereo outputs, you may con­nect one channel to each of Inputs 1

nd 2. However, you must remove

a
the shorting straps when using

tereo mode. Alternatively, you may

s

onnect each channel to a separate

c
SS88IWS. When using only one

nput on an individual SS88IWS, you

i
should leave the shorting straps in
place.

Using the SS88IWSBB Back Box

Whichever connection method you
choose to install the SS88IWSBB
back box, you will need to connect
all of the eight wires coming out of
the bottom of the back box to the
appropriate terminals on the loud­speaker. The wires are color-coded
as follows:

INPUT 1 (–): Yellow with black

stripe
INPUT 1 (+): Solid yellow
INPUT 2 (–): White with black

stripe
INPUT 2 (+): Solid white
OUTPUT 1 (–): Orange with

black stripe
OUTPUT 1 (+): Solid orange
OUTPUT 2 (–): Green with black

stripe
OUTPUT 2 (+): Solid green

he SS88IWSBB back box is an

T

ptional installation accessory for

o
the SS88IWS in-wall subwoofer.
When used, the SS88IWSBB back
box is installed during new con­struction before the wallboard.

Installation

1. Using the four flat-head screws,
install the two centering bars as
shown in Detail B in the draw­ings. The centering bars are for
setting the depth of the enclo­sure. They also help locate the
left/right position of the enclo­sure as they can be mounted
into the studs on the left and
right to hold the enclosure in the
correct location before final
mounting.

Using the eight #10 32 x 1" screws,

2.
install the four L-brackets
four corners of the enclosure.
Each of the eight screws should
have both the split washer and
flat washer installed; the split
washer goes on first. Leave the
screws a half-turn loose at first
to allow for adjustment later
(see Detail A). Do not screw the
L-brackets into the wall studs at
this time (see step 6).

3. Fit the enclosure into the wall.
The bottom edge of the bottom
L-brackets will rest against the
baseboard two-by-four. At this
time, make note of adjustments
necessary to square the enclo­sure into the wall (see Detail C).

4. After refitting and tightening the
L-brackets into the enclosure
(but not the wall studs yet), fit
the enclosure into the wall once
again.

at the

At this time, you may want to

5.
screw through each side of the
wood centering bars to mount
the enclosure to the studs. This
will help hold the enclosure in
position before the L-brackets
are mounted to the studs.

6. Screw the L-brackets into the
studs, using the eight wood

crews.

s

. Remove the wood centering

7

bars and replace the flat-head
screws into the holes left over
(the holes left in the cabinet
face underneath the bars are
also counterbored to accept the
flat-head screws).

8. The enclosure is now installed
and ready for the wallboard to
be installed over it.

9. Make the connections from
your receiver/amplifier to the
SS88IWS back box connections
panel, and to any other speak­ers as appropriate for your sys­tem, following the instructions
on the previous page. Connect
the eight wires hanging from the
bottom of the SS88IWSBB back
box to the correct terminals on
the SS88IWS loudspeaker (see
the previous page).
