Models T90 LR, T90 C, and T90 SR
surround sound, optimum placement of your T90 LR speakers is 2 to 3 feet to either side of the TV
screen and 1 to 2 feet out from the wall, at ear height when you’re seated. The left 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 be disconnected from the screen, distracting you from the picture. You should try
“toeing” the LR speakers in, aiming them at the prime listening position, to see if you prefer the
resulting sonic balance more. This can be particularly useful if the LR speakers must be fairly far apart.
The T90 C should be placed directly above or below the TV screen. It’s important that the speaker is
centered on the screen, not off to the side. Place the separate speaker base so that the foot “cutouts”
are closest to the front. Sit the speaker’s feet in the cutouts and tilt the speaker so that it points most
directly at the listening position. Try to keep the T90 C no more than 2 feet above or below the LRs.
The T90 C includes a rear mounted High Frequency Level control that adjusts the output of the
tweeter. You should adjust this control to get the three front speakers to sound as much alike as
possible when you set up your system. Most contemporary receivers include a random noise test tone
for setting the speaker levels. While listening to the random noise test tone, have someone adjust the
High Frequency control to match the three front speakers.
IMPORTANT NOTE: Most surround sound decoders and receivers offer a choice of “Normal” or “Wide-
band” or “Large” and “Small” modes for the some or all of the speakers in the set up menus. All T90
speakers must be used in the Normal or Small mode, if this choice is available.
