JBL New Construction, Included With the HTI88BB, L-brackets 8#10 32 x 1 screws, Installation

NEW CONSTRUCTION

You may either purchase the optional HTI88 back box kit, or you may install the speaker after the wallboard has been installed by following the instructions for existing construction on page 8.

INSTRUCTIONS FOR INSTALLING THE HTI88 USING THE HTI88BB BACK BOX KIT

The HTI88BB enclosure (“back box”) is optional. If desired, it is installed during new construc- tion before the wallboard is installed.

Included With the HTI88BB:

(4) L-brackets

(8)#10 32 x 1" screws

(8)#10 split washers

(8)#10 flat washers

(8)#8 x 3/4" woofer screws

(2)wood centering bars

(4)#10 32 x 1-1/2" flat-head screws

Installation:

1.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 at the left and right to hold the enclosure in the correct loca- tion before final mounting.

2.Install the four L-brackets to the four corners of the en- closure. 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 necessary to square the enclosure into the wall (see Detail C).

4.After refitting and tightening the L-brackets into the enclo- sure (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.
