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 tha t it is resting on a table or the floor , with the fla ps spread out and awa y . 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 rub ber stick-on feet that should be a pplied to prevent an y dama ge to either the speaker or the surface on which it is resting. (See Figure 1.) P L A C E M E N T Y our THX Ultra2 loudspeakers will achieve optimum performance when loca ted in conformance with THX guidelines, on which the following instructions are based. Dont be discouraged if some compromise is necessar y , 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 rela tively 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 T echnology) surround speakers, which offer man y more practical placement options than conventional designs. In the end, all that matters is what sounds good to you and wha t works in your home theater . Before we move on to the specifics, here are some placement considera tions that appl y universall y . General Rules - Front speakers typicall y sound best when their tweeters are at approximately ear height for sea ted listeners. If this isnt possible (as it often is not for center -channel speakers), it is sometimes beneficial to tilt the speaker slightly so tha t it is aimed into the listening area. Surround-channel speakers usually perf orm best when placed slightl y a bove sea ted ear level. - If you are putting speakers in a ca binet, tr y to bring their fronts out far enough tha t the y are at least flush with the ca binet s front. - When practical, arrange each speaker so tha t 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 a t dif ferent distances from their nearest side walls. This sort of sta g gering helps smooth the bass range. - An y speaker s bass output and response is strongly influenced b y its distance from room boundaries, such as walls and the floor . Moving a speaker closer to a room boundar y will increase its bass output, while moving it away will reduce the bass. So you will get maximum bass from a speaker b y 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 la yout. (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 installa tions, it ma y be preferable to use KS-525-THX s for the surround back channels due to their smaller size. Their WDST design works ver y well in this applica tion. T wo KW-120-THX subwoofers are necessar y to achieve THX Ultra2 maximum output requirements. This specification assumes a ver y large room, however , and in man y installations a single Figure 1

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, preferabl y 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 ideall y mounted on the back wall. Like the left and right surrounds, they should be slightl y 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 ver y well in this application. Y ou will probably want to space the KS-525-THX surround back pair somewhat farther a part than you would the LCR s. Subwoofers T wo KW -120-THX subwoofers and a KA-1000-THX amplifier are required to meet THX Ultra2 maximum output requirements. This specification assumes a ver y large room, however , and in man y installa tions 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 orienta tion is not at all critical, a void placing the front (driver) side of the cabinet up a gainst 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 usuall y will get best performance b y placing them together in the same loca tion ra ther than b y spacing them apart. Naturall y , 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 a t 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 sound quality. Please follow these directions carefully. Sloppy connections can cause amplifier malfunction or damage. Klipsch THX Ultra2 loudspeakers are internall y wired with custom Monster Cable® Z-Series speaker wire. Its Frequency Specific-„¢ design employs multiple gauges of high-purity cop - per wire, carefull y selected and wound to ensure optimum signal transfer a t all frequencies. Y ou will obtain best perf ormance from your speakers if you connect them to your amplifier or receiver with Monster Cable or similar high quality wire availa ble from your dealer . (The KW -120-THX comes with a 20-foot length of Monster THX Ultra-certified 1000 Series speaker ca ble termina ted in professional-grade Neutrik ® NL2 Speakon ® connectors tha t 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. W e will explain ordinary single-wiring first and then the alternatives. All the informa tion regarding single-wiring also applies to bi-wiring. B U T F IR S T: T Y P E S O F C O N N E C T O R S Bare wire. Pull the two conductors apart for about an inch and strip a pproxima tel y 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.) T wist 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 an y strands from the other conductor . Failure to obser ve 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 a part. Front LCR Loudspeakers Normally the array would be either all KL-650-THXs or all KL-525-THXs, but the center speaker can be dif ferent 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 a bove 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. Exactl y how far out depends on the size of the screen. A reasona ble starting point is to place the left and right speakers so tha t 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 ha ve the left and right speakers spread a little too wide than to ha ve 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 desira ble to wall-mount the front LCR speakers rather than to put them on stands or in a ca binet. T o accommoda te 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 Loudspeakers In a 5.1- or 7.1-channel installation the left and right surround speakers will be KS-525- THX s placed to the sides of the listening area, typically on or a gainst the walls. They should be elevated slightly a bove 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 T echnology design g ives you a great deal more la titude if you need it, delivering good results in configura tions that depart significantly from the ideal. The KS-525-THX has a keyhole mount for use in hang ing the speaker on the wall. T o use the keyhole, all you need is a screw or nail of the appropria te size protruding slightl y from the wall. If possible, the nail or screw should be driven into a wall stud; if not, be sure to use appropria te anchors in the dr y- wall or plaster . Additionall y , 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.
