SPEAKER PLACEMENT

It is best to establish the locations for the speakers in advance, to avoid having to correct errors after installation has already begun. Refer to these guidelines, and also see the owner’s guide for the HTI88 subwoofer for more information.

It is generally recommended that you install your HTI88 in-wall subwoofer along the same wall as the front loudspeakers. The HTI88 subwoofer is not video-shielded and should not be placed near a video

display. Installing the HTI88 near a corner will tend to maximize lowfrequency output. Be cautious when installing in a corner, to avoid a “boomy” sound. Also take into consideration any unusual features of the room, such as an alcove, which may tend to create a localized node that may affect bass response in that area of the room.

It is generally recommended that the speaker be installed so that the bottom of the speaker is approximately 12" from the floor. Note that installing the speaker within the 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.

OWNER’S GUIDE

SPEAKER CONNECTIONS

Connection Tips

Refer to page 4 of the HTI88 subwoofer owner’s guide for general information on speaker-wire connections. This manual includes connection guidelines that are specific to the HTI88BB back box.

To use the push-type terminals on the connections panel supplied with the HTI88BB back box enclosure, depress the colored cap until the pass-through hole in the binding post is revealed. While holding the 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 amplifier or your main receiver/amplifier to power the 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

right speaker-level outputs on your receiver/amplifier to the Input 1 (for left channel) and Input 2 (for right channel) connectors on the HTI88 connection panel. Connect the Output 1 terminals to the corresponding terminals on your front left speaker, and the Output 2 terminals to the corresponding terminals on your front right speaker.

NOTE: When using Connection Method #1 with only one HTI88, the shorting straps must be removed.

If you are using two HTI88 subwoofers, connect the left speaker outputs 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 left-channel subwoofer to the inputs 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.

Connection Method #2

Use this method when you are using the HTI88 with a dedicated subwoofer amplifier. Connect your main receiver/processor’s line-level subwoofer output to the line-level input on your subwoofer amplifier. Connect the speaker terminals on your subwoofer amplifier to either Input 1 or Input 2. If your amplifier has stereo outputs, you may connect one channel to each of Inputs 1 and 2. However, you must remove the shorting straps when using stereo mode. Alternatively, you may connect each channel to a separate HTI88. When using only one input on an individual HTI88, you should 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

INSTALLATION

Although the JBL HTI Series inwall speakers were designed to be easily installed in existing construction applications, it is recommended that installation of the HTI88BB back box in new construction be reserved for professionals. See the manual for the HTI88 subwoofer for instructions on installing the speaker in existing construction without using the back box.

The HTI88BB back box is an optional installation accessory for the HTI88 in-wall subwoofer.

When used, the HTI88BB 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.

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 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.

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.

De

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

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, following 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 previous page).
