Models 371 LR, 373 C, and 374 SR

The degree of front speaker toe-in can affect the imaging and response characteristics of the speakers.

In most rooms, the speakers will work well facing straight ahead or slightly toed-in towards the

listener. Speakers that are placed close to the side walls may require additional toe-in to avoid a poor

image and/or a forward midrange and treble response due to reflections from the side walls. Play some

two channel stereo music and experiment with speaker positioning.

Note: If the speakers need an excessive amount of toe-in to image properly, there may be a problem with the

connection of the speakers or some part of the system may not be operating properly. Check all of your

speaker wire connections for correct phase and verify that the associated components in the system are

connected and functioning properly.

The Model 373 C Center Channel Speaker should be centered between the left and right front

speakers and above or below the TV screen. It should be tilted on its adjustable base to direct the

sound toward the listening position. Ideally, the center channel speaker should be placed within two

feet of the axis of the front channel tweeters. This placement is somewhat flexible, however, because of

the directability of the 373 C on its tiltable base. The 373 C is usually placed on top of the TV, or above

or below the screen in a front projection video system.

The Boundary Compensation Control on the rear panel of the 373 C provides a unique way to

fine-tune the frequency balance of the speaker when it is placed on or near a reflective surface. In

Conversely, if there doesn't seem to be enough midrange frequencies, if voices sound muffled for

example, flip the switch to the free air, THX reference position to increase these frequencies.

For free-air use, and to meet THX specifications, keep the switch of the boundary compensation

control in the THX position.

The Model 374 SR Surround Speakers should be placed at the sides of the room with the null

(the point of the triangle between the two sets of drivers) of the speakers aimed at the listening

position. Height of the surrounds should be between ear level and two feet above ear level.

If there is more than one row of seats, the surround speakers should be at the sides of the room at the

geometrical center of the seating positions. Some people prefer to have the surround speakers mounted

high up on the side walls, slightly behind the listening position. If this is the case, the speaker should

be mounted upside-down to position the tweeters at the bottom of the cabinet. This will acoustically

position the speaker lower on the wall. This mounting position can provide a larger sense of "space"

and may be the only choice in some rooms.

many situations, the unfortunate audible result of placing a

speaker on top of a TV is a boost in the midrange response

from the sound reflecting off of the TV screen. This can often

result in harsh midrange and treble response and a blurring of

the sound when you are sitting off to the side.

Once you have the speaker in position, put on some music

or a movie with good center channel information. Sit down

and listen for a few minutes. If you find the midrange response

exaggerated, flip the switch to the boundary compensation

position. This will reduce the level of midrange frequencies.
