best results, place
the surround

that the surround

important that the
speakers be placed
correctly for proper
imaging.

Home Theater
Remember that the primary goal of a good Home Theater is not to make you believe that you are in a
movie theater. It’s to make you believe you are in the scene taking place on the screen. For a Home
Theater system, place your Model 4.5 LR speakers on either side of the television. The three front
channel speakers (4.5 LRs and 4.5 C) are magnetically shielded so they will not interfere with your
television picture. 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 to come directly from the speakers, dis-
tracting you from the picture. If you are using a center channel speaker, a wider separation of the left
and right front speakers is usually possible. You may chose to “toe” the LR speakers in, aiming them at
the prime listening position. This can be particularly useful if the front LR speakers are fairly far apart.
The Model 4.5 C should be placed directly above or below your television. It is important that the
speaker is centered on the screen, not off to the side. Place the speaker base so that the foot cutouts are
facing forward. Then pivot the speaker on its base, tilting it so that it points most directly at the
listening position.
Operation of the HI FREQ LEVEL Control
The HI FREQ LEVEL control will give you more or less high frequency output from
the speaker, working similarly to the treble tone control on a preamp, amp or
receiver. This allows you to compensate for overly bright soundtracks or “punch
up” a dull soundtrack. Turning this control clockwise increases the high frequency
level; turning it counterclockwise reduces the high frequency level. The HI FREQ
LEVEL control also will allow you to adjust the overall sonic balance of the 4.5 C to
more closely match the LR speakers, even though the 4.5 C is placed directly above
or below the TV screen.
