SPEAKER

LACEMENT

P

It is best to establish the locations
for the speakers in advance, to

void having to correct errors

a
after installation has already

egun. Refer to these guidelines,

b

nd also see the owner’s guide for

a
the HTI88 subwoofer for more

nformation.

i
It is generally recommended that

ou install your HTI88 in-wall sub-

y
woofer along the same wall as the

ront loudspeakers. The HTI88 sub-

f
woofer is not video-shielded and
should not be placed near a video

isplay. Installing the HTI88 near a

d
corner will tend to maximize low-

requency output. Be cautious

f
when installing in a corner, to
avoid a “boomy” sound. Also take

nto consideration any unusual

i
features of the room, such as an

lcove, which may tend to create

a

localized node that may affect

a
bass response in that area of the

oom.

r
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
HTI88BB 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 HTI88 sub-

oofer owner’s guide for general

w
information on speaker-wire con-

ections. This manual includes con-

n

ection guidelines that are specific

n
to the HTI88BB back box.

To use the push-type terminals on
the connections panel supplied with

he HTI88BB back box enclosure,

t
depress the colored cap until the
pass-through hole in the binding

ost is revealed. While holding the

p
cap down, insert the bare end of
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 HTI88 is a passive loud­speaker, only speaker-level connec­tions are available. Depending on
whether you are using a dedicated
subwoofer
receiver/
HTI88, select one of the two connec­tion methods that follow.

Connection Method #1

Use this method when you are using
the HTI88 with your main receiver/
amplifier. Connect the main left and

amplifier or your main

amplifier to power the

ight speaker-level outputs on your

r

eceiver/amplifier to the Input 1 (for

r
left channel) and Input 2 (for right

hannel) connectors on the HTI88

c

onnection panel. Connect the

c
Output 1 terminals to the correspon-

ing terminals on your front left

d
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 HTI88, the

M
shorting straps must be removed.

If you are using two HTI88 sub­woofers, connect the left speaker out-

uts on your receiver/

p

mplifier to

a
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 HTI88 in this mono
mode, you should not remove the
shorting straps.

onnection Method #2

C

se this method when you are using

U
the HTI88 with a dedicated sub-

oofer amplifier. Connect your main

w

rocessor’s line-level sub-

p

eceiver/

r
woofer

output to the line-level input

n your subwoofer amplifier.

o
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
HTI88. When using only one input on

n individual HTI88, you should

a
leave the shorting bars in place.

Using the HTI88BB Back Box

Whichever connection method you
choose, to install the HTI88BB 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
