[. . . ] In 7. 1channel applications, place two of the surround speakers in the side positions, and place the two surround back speakers on the rear wall. In Dolby* Digital and DTS® systems, it is best to aim all of the speakers (except the subwoofer) toward the listening position at about ear-level height. In systems where only analog surround processing (such as Dolby Pro Logic*) is available, it may be preferable to aim the speakers straight out from the wall to obtain a more diffuse sound. The low-frequency material reproduced by the subwoofer is mostly omnidirectional, and this speaker may be placed in a convenient location in the room. However, bass reproduction will be maximized when the subwoofer is placed in a corner along the same wall as the front speakers. Experiment with subwoofer placement by temporarily placing the subwoofer in the listening position and moving around the room until the bass reproduction is best.

On the wall. Wall brackets are included. On optional stands. ATTACHING THE SHELF STAND TO THE SPEAKER 1. Thread the two conductors through the two holes in the stand bracket. The floor stand adaptor screws may be found in Hardware Bag B. Use the larger screw in the upper screw hole, and the smaller screw in the lower screw hole. Screw the floor stand adaptor into the floor stand's threaded insert until the speaker is firmly attached to the stand. Back off slightly from the fully-tightened position until the speaker is oriented as desired, then rotate the thumbwheel at the bottom of the floor stand adaptor to secure the speaker to the stand. Slide the Molded Nut onto the Ball and Shaft with the threaded opening facing the ball. Thread the metal nut all the way onto the Ball and Shaft, with the star washer side away from the ball. Refer to the exploded drawing for the proper orientation of these parts. Screw the Ball and Shaft into the Threaded Insert on the back of the Satellite Speaker until it is fully seated in the Threaded Insert, but do not tighten as you might dislodge the Threaded Insert. Such damage would not be covered under the warranty. Tighten the Metal Nut with the star washer side between the Metal Nut and the back of the Satellite Speaker, using large needle-nose pliers, until it is firmly seated against the back of the Speaker and has locked the Ball and Shaft and the Satellite Speaker together. Note that once the Metal Nut is fully tightened, it may embed some marks on the back of the Satellite Speaker. However, these marks will be covered by the Metal Nut. Mount the Attachment Plate into a wood stud on the wall, using four #10 pan-head wood screws at least one inch long (not supplied). [. . . ] (c) In Dolby Digital or DTS modes, make sure that the receiver/processor is configured so that the speaker in question is enabled. (c) Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly. Turn everything back on, and determine whether the problem has followed the speaker, or has remained in the same channel. If the problem is in the same channel, the source of the problem is most likely with your receiver or amplifier, and you should consult the owner's manual for that product for further information.
