INSTALLATION

Although the JBL HTI Series in-

w

all speakers were designed to

be easily installed in existing con-

struction applications, it is recom-

m

ended that installation of the

HTI88BB back box in new con-

s

truction be reserved for profes-

s

ionals. See the manual for the

HTI88 subwoofer for instructions

o

n installing the speaker in exist-

ing construction without using

t

he back box.

T

he HTI88BB back box is an

optional installation accessory

f

or the HTI88 in-wall subwoofer.

When used, the HTI88BB back box

is installed during new construc-

tion before the wallboard.

Installation

1. Using the four flat-head screws,

install the two centering bars as

shown in Detail B in the draw-

ings. The centering bars are for

setting the depth of the enclo-

sure. They also help locate the

left/right position of the enclo-

sure as they can be mounted

into the studs on the left and

right to hold the enclosure in the

correct location before final

mounting.

2. Using the eight #10 32 x 1"

screws, install the four L-brack-

ets at the 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

to 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 2 x 4. At this time,

make note of adjustments nec-

essary 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.

5.

At this time, you may want to

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

s

crews.

7

. Remove the wood centering

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 HTI88

back box connections panel,

and to any other speakers as

appropriate for your system, fol-

lowing the instructions on the

previous page. Connect the

eight wires hanging from the

bottom of the HTI88BB back box

to the correct terminals on the

HTI88 loudspeaker (see the pre-

vious page).
