These recommendations are for the optimal placement of the loudspeakers, and should be used as a guide. Slight variations will not diminish your listening pleasure. The following HKL Series loudspeakers are video-shielded and may safely be placed near a television or video display: HKB 4, HKB 6, HKTW 6 and HKC. The HKSUB 12 subwoofer is not videoshielded, and should be placed at least three feet away from any CRT video display devices, including televisions and computer monitors. Front Speakers (HKB 4, HKB 6, HKTW 6) Center Channel Speaker (HKC) Surround Speakers (HKB 4, HKB 6) 0-2 ft. Model HKC is suitable for use as the center channel speaker in a multichannel home theater system. The center channel speaker should be placed slightly behind the front left and right speakers. It is often convenient to set the center speaker on top of the television set, as shown in the drawing, or it may be placed on a shelf above or below the television or video display. The tweeter of the center speaker should be no more than two feet above or below the tweeters of the main left and right speakers. 5 ­ 6 ft. Models HKB4 and HKB 6 are suitable for use as the side or rear surround speakers in a multichannel home theater system. The two side surround speakers should be placed slightly behind the listening position and, ideally, should face each other and be at a level higher than the listeners' ears. If that is not possible, they may be placed on a wall behind the listening position, facing forward. In a 6. 1- or 7. 1-channel system, in which surround back speakers as well as side surround speakers are used, you may place one pair of speakers to the sides, and a second pair of speakers on the rear wall, facing forward, as shown in the diagram. The surround speakers should not call attention to themselves. Experiment with their placement until you hear a diffuse, ambient sound accompanying the main program material heard in the front speakers. Models HKB 4, HKB 6 and HKTW 6 are suitable for placement in the front left and right speaker locations in either a twochannel system or a multichannel home theater system. The front speakers should be placed the same distance from each other as they are from the listening position, and they may be "toed in, " or angled slightly, toward the listening position. They should be placed at the same height as the listeners' ears. SPEAKER PLACEMENT 9 SPEAKER PLACEMENT Powered Subwoofer (HKSUB 12) HKSUB 12 As a general rule, bass response increases as a subwoofer is placed closer to a wall. Therefore, bass output is maximized when the subwoofer is placed in a corner. We recommend that you place the HKSUB 12 along the same wall as the front loudspeakers, as shown in the diagram. Low-frequency sounds are normally omnidirectional, meaning the listener cannot localize them to a specific place in the room. However, frequencies between 75Hz ­ 150Hz can be localized, especially at higher volume levels. Positioning your subwoofer as recommended will provide the most natural soundstage and imaging from your loudspeaker system.
