Models 371 LR, 373 C, and 374 SR

Mounting
The Model 371 LR and Model 374 SR speakers can be mounted in a variety of ways:
On the wall.
To surface mount your speakers on the wall, we have provided two steel keyhole
brackets already installed on the back panel of the cabinet. Simply place the large openings of the
bracket over the heads of pan-head screws (securely screwed into wall studs or wall anchors), and slide
the cabinet down onto the shaft of the screw. Ideally, the acoustic center of the speaker (the tweeter)
should be within two feet of ear level when you are in a seated position.
On optional pedestal stands.
The pedestal stands are provided with complete instructions and all
necessary hardware required for installation. These stands allow placement flexibility and a stable base
for a variety of floor surfaces, including deep pile carpeting. The height of the pedestal stand is
matched to the speaker for optimum performance.
Positioning the Speakers
Place the
Model 371 LR Front Speakers
to the left and right of the TV screen. All of the System 370
THX speakers, except for the 374 SR surround speakers, are magnetically shielded and will not interfere
with the video image. The left front and right front speakers should be far enough apart that you get a
good stereo image, but not so far apart that the sound seems distant and distracting. Avoid placing the
speakers too close to a corner or too close to the TV, and try to maintain an equal distance from the
screen on both sides.
