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. RISK OF ELECTRIC SHOCK DO NOT OPEN U N P A C K I N G 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. Dont 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. G General Rules-Front speakers typically sound best when their tweeters are at approximately ear height for seated listeners. If this isnt 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 cabinets 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 speakers 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 ConfigurationFigure 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 LCRs 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 LCRs. In some installations, it may be preferable to use KS-525-THXs 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 Figure 1

SSurround Back LoudspeakersIn 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 LCRs, 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-THXs 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 LCRs. SubwoofersTwo 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 subwoofers orientation is not at all critical, avoid placing the front (driver) side of the cabinet up against a wall. - The subwoofers 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, thats 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. C O N N E C T I O N S Note: Proper connection of your speakers to your amplifier or receiver is vital to obtaining good soun d quality. Please follow these directions carefully. Sloppy connections can cause amplifier malfunctio n 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 cop- per 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 mini- mum, we recommend that you use 16-gauge or heavier stranded copper wire. Use lower- gauge (heavier) wire for long runs to maintain correct frequency response and minimize power loss. 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. BUT FIRST: TYPES OF CONNECTO 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. 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. Front LCR LoudspeakersNormally 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 cen- ter-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-525- THX are both configured for use with OmniMount ®60.0 Series wall-and ceiling-mount brack- ets (See Figure 3). Refer to the OmniMount manual for detailed installation instructions. Surround Left and Right LoudspeakersIn a 5.1- or 7.1-channel installation the left and right surround speakers will be KS-525- THXs 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-THXs 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 dry- wall 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.
