HT 1S - JBL Audio User Guide / Operation Manual. Page 3

The Center channel front speaker
should be positioned vertically
and centered either above or
below the middle of the screen (or
behind the screen if you have a
projection T.V. with a perforated
screen). All three front speakers
should be mounted "flush" to the
screen and in the same plane
relative to the screen.
The Left and Right should be at
the exact same height, and the
Center should be no more than 2
feet higher or lower. Your Center
channel speaker must be vertically
oriented. Turning it on its side will
prevent your HT1 system from
producing the correct sound field.

The Subwoofers can be placed
on either side of the screen or in
the corners of the room. A good
configuration for a mono
amplifier/dual HT1S setup that
lessens the effect of room modes
is one subwoofer in a corner, the
other in the middle of a wall.

PLACEMENT
Placing your speaker components
properly is vital to achieving the
correct sonic performance. Please
read the following sections
carefully for proper placement.
They are  divided into front
channel speakers (HT1F: Left-
Center-Right), subwoofers
(HT1S), and dipolar surround
speakers (HT1D).

The Left and Right front channel
speakers should be located on
either side of the T.V. screen or
projector. Closer to the screen
gives you more localization while
farther (two to three feet from the
screen on each side) will give you
a wider sound field. Ideally, you
want to try to put the speakers
about 45 degrees apart from each
other, viewed from the listening
position. The center line of the
speaker (the area between the two
tweeters) should be at the same
height as actors on the screen
would be. Depending on the
height of your T.V. screen, you
may be able to place the Left and
Right speakers directly on top of
your subwoofer cabinets. If your
screen height doesn't allow this,
you may place the Left and Right
speakers on a speaker stand to
achieve the proper height.
Depending upon your
configuration, you may also need
a stand for the center speaker that
tilts it so that it points towards the
listener's ear level. Your JBL
dealer can help you purchase a
stand that meets your height
requirement.
