SPEAKER PLACEMENT

Low-frequency sounds are

normally omnidirectional,

meaning the listener can’t tell

where they are generated from.

However, frequencies between

75Hz and 150Hz can be local-

ized, especially at higher vol-

ume levels. Positioning your

subwoofer as recommended

will provide the most natural

soundstage and imaging from

your loudspeaker system.

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 cor-

ner will tend to maximize low-

frequency 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. This is to help with the

low-frequency loading (bass

reinforcement). This also helps

hide the speaker in a less visi-

ble place. In special circum-

stances it is acceptable to

install the speaker at any

height on a wall.

Remember that these are just

guidelines. Since every listen-

ing room is different, JBL

strongly recommends experi-

menting 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 bor-

row a stand-alone subwoofer

and place it near the main lis-

tening location. Then move

around the room and determine

where you hear the most pleas-

ing bass performance. This

would then be the ideal location

for the subwoofer.

When using two HTI88 in-wall

subwoofers, you may need to

be concerned about phase,

as the sound waves may

cancel each other out. If bass

response seems low, try in-

verting the polarity on one sub-

woofer – i.e., connect the (+)

terminal on the amplifier to the

(–) terminal on the speaker, and

the (–) terminal on the amplifier

to the (+) terminal on the

speaker.
