Speaker positioning is very important as it affects the overall sound quality of the system. Place the speakers in locations that will optimize the sound quality at your listening position. The position of the subwoofer is not as critical as the position of the other speakers because low bass tones are not highly directional. Refer to "Positioning the subwoofer (SW-P270)" on page 4 for more information. Positioning the front and surround speakers (NX-E270) Non-skid pad Note: These speakers are magnetically shielded. However, if you place them too close to a TV, they may impair picture color. In this case, move the speakers further away from the TV. Front speakers: Place the two front speakers on the left and right sides of the TV, at approximately the same height as the TV, facing directly forward. Surround speakers: Place the left and right Front R TV-set Front L Center Surround R Subwoofer surround speakers behind your listening position, facing slightly inward, about 1. 8 m (approx. 6 feet) above the floor. Surround back speaker (for NS-P276 systems only): Position the surround back speaker behind your listening position, precisely between the surround speakers, about 1. 8 m (approx. 6 feet) above the floor. Surround back (for NS-P276) Surround L You can set the front, surround, and surround back speakers on tables or other supports, or mount them on a wall or speaker stand. (For more information, see "Mounting the front and surround speakers" on page 5. ) Non-skid pads: When placing the speakers on a flat surface, attach the included non-skid pads to the corners of the speaker bottoms, as shown above. The non-skid pads will prevent the speakers from sliding. 3 Positioning the center speaker (NX-C270) Place the center speaker precisely between the front speakers, facing directly forward. You can place the center speaker on top of a TV (if the top of the TV is flat), on the floor beneath the TV, or in an entertainment center. Be sure to place the speaker in a stable location. When placing the speaker on top of a TV rack, etc. , to prevent the speaker from falling, attach the provided fasteners at two points on the bottom of the speaker and on top of the TV, as illustrated below. Positioning the subwoofer (SW-P270) It is recommended to place it on the outside of either the right or the left front speaker. B is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may lessen because the sound from it and the sound reflected by the wall may cancel out each other. To prevent this from happening, face the subwoofer system at an angle as in fig. A. Note: There may be a case that you cannot obtain enough super-bass sounds from the subwoofer when listening in the center of the room. This is because "standing waves" have been developed between two parallel walls and they cancel the bass sounds. In such a case, face the subwoofer obliquely to the wall.
