UNPACKING
The easiest way to remove the speaker from its carton is to turn the open end of the box
down so that it is resting on a table or the floor, with the flaps spread out and away. Then
pull the box straight up and off. Remove any packing material from the speaker and grille,
place it back in the carton, and store in case you ever need to ship the loudspeaker. Each
speaker comes supplied with rubber stick-on feet that should be applied to prevent any
damage to either the speaker or the surface on which it is resting (Figure 1).
PLACEMENT
Your THX Ultra2 loudspeakers will achieve optimum performance when located in
conformance with THX guidelines, on which the following instructions are based. Don’t be
discouraged if some compromise is necessary, however, or if modest adjustments will
make the system look much better in the room. The speakers are engineered to deliver
excellent sound over a relatively wide range of placements within the basic framework of a
5.1-, 6.1-, or 7.1-channel surround-sound installation. This is especially the case for
WDST™ (Wide Dispersion Surround Technology) surround speakers, which offer many
more practical placement options than conventional designs. In the end, all that matters is
what sounds good to you and what works in your home theater.
Before we move on to the specifics, here are some placement considerations that apply
universall
y.
General Rules
• Front speakers typically sound best when their tweeters are at approximately ear height
for seated listeners. If this isn’t possible (as it often is not for center-channel speakers), it
is sometimes beneficial to tilt the speaker slightly so that it is aimed into the listening
area. Surround-channel speakers usually perform best when placed slightly above
seated ear level.
• If you are putting speakers in a cabinet, try to bring their fronts out far enough that they
are at least flush with the cabinet’s front.
• When practical, arrange each speaker so that its woofer is at somewhat different
distances from the floor, the wall behind it, and the wall beside it. It can also help to
have the left and right front speakers at different distances from their nearest side walls.
This sort of staggering helps smooth the bass range.
• Any speaker’s bass output and response is strongly influenced by its distance from room
boundaries, such as walls and the floor. Moving a speaker closer to a room boundary will
increase its bass output, while moving it away will reduce the bass. So you will get
maximum bass from a speaker by placing it in a corner and minimum bass by placing it
in the center of the room.
System Configuration
Figure 2 shows a THX-Ultra2 compliant 7.1-channel speaker layout. (Configuration for 5.1
channels is the same minus the surround back loudspeakers behind the listening area.)
KL-650-THX or KL-525-THX LCR’s are used for front left, center, and right channels.The
left and right surrounds are KS-525-THX WDST™ loudspeakers.The surround back
speakers are narrowly spaced KL-650-THX or KL-525-THX LCR’s. In some installations, it
may be preferable to use KS-525-THX’s for the surround back channels due to their
