Top speaker placement guidelines
Top speakers, such as Top Forward (TFwL, TFwR), Top Middle (TMdL, TMdR) or Top Backward (TBwL, TBwR),
are placed above the listener position on the ceiling.

! All top speaker pairs should preferably be mounted along a vertical line that is a ±30º horizontal from the
center-front reference. However, these speakers may be placed as far as the side walls and anywhere between
the side walls and the middle of the room, if needed.
! We also recommend that the top forward speakers and top backward speakers be installed at a symmetrical
distance from the front and rear of right above, respectively.

! The height of the Top Forward, Top Middle and Top Backward speakers mounted on the ceiling should prefer-
ably be no more than three times the height and no less than two times the height of the front speakers at
listener height.
! The Top Forward, Top Middle and Top Backward speakers should be directed straight down, rather than
directed at a central listener position.
! We recommend that the top middle speakers be installed slightly forward from right above.

Some tips for improving sound quality

Where you put your speakers in the room has a big effect on the quality of the sound. The following guidelines
should help you to get the best sound from your system.
! The subwoofer can be placed on the floor. Ideally, the other speakers should be at about ear-level when you're
listening to them. Putting the speakers on the floor (except the subwoofer), or mounting them very high on a
wall is not recommended.
! For the best stereo effect, place the front speakers 2 m to 3 m apart, at equal distance from the TV.
! If you're going to place speakers around your CRT TV, use shielded speakers or place the speakers at a suffi-
cient distance from your CRT TV.
! If you're using a center speaker, place the front speakers at a wider angle. If not, place them at a narrower
angle.
! Place the center speaker above or below the TV so that the sound of the center channel is localized at the TV
screen. Also, make sure the center speaker does not cross the line formed by the leading edge of the front left
and right speakers.
! It is best to angle the speakers towards the listening position. The angle depends on the size of the room. Use
less of an angle for bigger rooms.
! Surround and surround back speakers should be positioned 60 cm to 90 cm higher than your ears and tilted
slightly downward. Make sure the speakers don't face each other. For DVD-Audio, the speakers should be
more directly behind the listener than for home theater playback.
! Try not to place the surround speakers farther away from the listening position than the front and center speak-
ers. Doing so can weaken the surround sound effect.
