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.
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. (See 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 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
