ABOUT YOUR KLIPSCH PURCHASE
Thank you for your purchase of Klipsch THX®Ultra2™loudspeakers. After reading this
manual and connecting your system, you will hear the results of over 55 years of stringent
engineering and class-leading research and development. Like all Klipsch products, your
loudspeakers feature Klipsch Tractrix®Horn-loaded Technology– the guiding design for the
first Klipschorn®developed in 1946 and for every product that has followed. Horn-loading
allows your speakers to deliver high sensitivity, low distortion, flat frequency response and
wide dispersion, which translates to unequaled power, detail, and dynamics, the hallmark of
“The Klipsch Sound.” Please be sure to fill out the warranty card at the back of this manual
or online at www.klipsch.com so we are better able to serve you. Again, thank you for
choosing Klipsch and we hope that your speakers bring life to your music and movies for
many years.

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. (See Figure 1.)

P L A C E M E N T
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
universally.
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
smaller size. Their WDST design works very well in this application. Two KW-120-THX
subwoofers are necessary to achieve THX Ultra2 maximum output requirements. This
specification assumes a very large room, however, and in many installations a single
KW-120-THX will be completely adequate. The companion KA-1000-THX subwoofer amplifier
can drive either one or two subwoofers. In dual-subwoofer systems, it is usually best to place
them right next to each other rather than spaced apart.
Figure 2
Front LCR Loudspeakers
Normally the array would be either all KL-650-THXs or all KL-525-THXs, but the center
speaker can be different from the left and right speakers. (For example, you might combine a
pair of KL-650-THXs for the front left and right with a KL-525-THX for the center.) The center-channel speaker should be centered along the width of the TV screen, directly above or
below it or, in the case of an acoustically transparent front-projection screen, behind it. The
left and right speakers should be placed equal distances out from the edges of the TV screen.
Exactly how far out depends on the size of the screen. A reasonable starting point is to place
the left and right speakers so that they and your listening position form an equilateral triangle.
Since the center speaker helps anchor the sound to the screen, it usually is better to have the
left and right speakers spread a little too wide than to have them too close together. The left
and right speakers should be aimed inward towards the listening position as shown in figure
2. In some installations, it may be desirable to wall-mount the front LCR speakers rather than
to put them on stands or in a cabinet. To accommodate this, the KL-650-THX and KL-525THX are both configured for use with OmniMount®60.0 Series wall-and ceiling-mount brackets (See Figure 3). Refer to the OmniMount manual for detailed installation instructions.
Surround Back Loudspeakers
In addition to the left and right surrounds, THX Ultra2 7.1-channel system specifications call
for two forward-radiating surround back loudspeakers behind the listening area, preferably
spaced no more than a few feet apart. These would be KL-650-THX or KL-525-THX LCR’s,
either placed on stands, or ideally mounted on the back wall. Like the left and right
surrounds, they should be slightly above seated ear level – about five to six feet off of the
floor. In some installations, it may be preferable to use KS-525-THX’s for the surround back
channels due to their smaller size. Their WDST design works very well in this application.
You will probably want to space the KS-525-THX surround back pair somewhat farther
apart than you would the LCR’s.
Subwoofers
Two KW-120-THX subwoofers and a KA-1000-THX amplifier are required to meet THX
Ultra2 maximum output requirements. This specification assumes a very large room,
however, and in many installations a single KW-120-THX will be completely adequate.
Although the KW-120-THX will perform well in a wide variety of locations, you will get the
most out of it by following some simple guidelines:
• Although the subwoofer’s orientation is not at all critical, avoid placing the front (driver)
side of the cabinet up against a wall.
• The subwoofer’s output will increase as it is moved closer to walls, with maximum output
when it is placed in a corner. If practical, always place the subwoofer against or near a
wall.
• In most rooms, a subwoofer will deliver smoothest bass response when placed in a
corner away from room openings, such as doors. So if possible, that’s the place to start.
• If you are using more than one subwoofer, you usually will get best performance by
placing them together in the same location rather than by spacing them apart.
Naturally, there are exceptions to the general rules, since no two rooms or systems are
exactly alike. Once you have the subwoofer connected to your system and adjusted at
least roughly (see the KA-1000-THX manual for details), you may want to experiment to
see if you can do better.

Note: Proper connection of your speakers to your amplifier or receiver is vital to obtaining
good sound quality. Please follow these directions carefully. Sloppy connections can cause
amplifier malfunction or damage.
Klipsch THX Ultra2 loudspeakers are internally wired with custom Monster Cable® Z-Series
speaker wire. Its Frequency Specific™ design employs multiple gauges of high-purity copper wire, carefully selected and wound to ensure optimum signal transfer at all frequencies.
You will obtain best performance from your speakers if you connect them to your amplifier
or receiver with Monster Cable or similar high quality wire available from your dealer. (The
KW-120-THX comes with a 20-foot length of Monster THX Ultra-certified 1000 Series
speaker cable terminated in professional-grade Neutrik®NL2 Speakon®connectors that
mate with the jacks on the subwoofer and the companion KA-1000-THX amplifier.) At minimum, we recommend that you use 16-gauge or heavier stranded copper wire. Use lowergauge (heavier) wire for long runs to maintain correct frequency response and minimize
power loss.
Figure 3
Surround Left and Right Loudspeakers
In a 5.1- or 7.1-channel installation the left and right surround speakers will be KS-525THX’s placed to the sides of the listening area, typically on or against the walls. They should
be elevated slightly above seated ear level – five or six feet above the floor is a good target. If
desired, the speakers can be moved back along the wall to as much as 20 degrees behind
the listening position, especially in a 5.1-channel system. The KS-525-THX’s Wide Dispersion
Surround Technology design gives you a great deal more latitude if you need it, delivering
good results in configurations that depart significantly from the ideal. The KS-525-THX has a
keyhole mount for use in hanging the speaker on the wall. To use the keyhole, all you need is
a screw or nail of the appropriate size protruding slightly from the wall. If possible, the nail or
screw should be driven into a wall stud; if not, be sure to use appropriate anchors in the drywall or plaster. Additionally, the KS-525-THX is configured for use with OmniMount®20.0
Series wall-and ceiling-mount brackets (See Figure 3). Refer to the OmniMount manual for
detailed installation instructions.
On the back of each KL-650-THX, KL-525-THX and KS-525-THX speaker are two sets of
binding posts, one feeding the tweeter and the other the woofers. For conventional wiring,
these sets are connected together with gold-plated metal straps, which can be removed for
bi-wiring or biamping. We will explain ordinary single-wiring first and then the alternatives.
All the information regarding single-wiring also applies to bi-wiring.
BU T FI RS T: T YP ES OF CO NN EC TO R S
Bare wire. Pull the two conductors apart for about an inch and strip approximately 1/4-inch
of insulation from the end of each. (A wire stripper will simplify this, but you can use an
ordinary pocket knife to cut around and through the insulation down to the wire.) Twist the
strands of wire on each individual conductor tightly together. Loosen the nuts on a pair of
binding posts until the holes through the metal posts are exposed, then insert the bare wire
through the holes. Screw the nuts down finger-tight on the wire. Make sure that no strands
of wire are touching from one binding post to the other or to any strands from the other
conductor. Failure to observe this precaution at either end of the connection can result in
amplifier malfunction or damage.
Pins. Many pre-made speaker cables are terminated with metal pins. Loosen the nuts on a
pair of binding posts until the holes through the metal posts are exposed, then insert the
pins through the holes. Screw the nuts down finger-tight on the pins — do not overtighten.
