New Construction Wings Bracket Frame Speaker Baffle Grille Recommended Amplifier Power For satisfactory performance, we recom- mend an amplifier with a power rating of twenty to two hundred watts for the A T8500 and A T8700 speakers. Curiously , most speakers are not damaged by large amplifiers but by small amplifiers.
are connected in line with the speaker , so you must connect the wire from the ampli- fier to the volume control and then from the volume control to the speaker . Speaker Wire Use 2-conductor speaker wire when con- necting A T speakers to your receiver or amplifier .
appreciate the tighter bass and extended frequency response into the lower octaves that the use of a backbox (or blocking off the wall cavity) will provide. A hole cutting template is provided with the A T8000 Series Bracket Kit. The cutout for the speak- er must measure 9 -3/4” x 1 7 -1/4”.
clarity , detail and the textures of the individ- ual instruments, you are a critical listener . In a home theater , the intelligibility of dialog and action reproduced by the front speakers is paramount! The position of the speakers plays a very important role in how clear the sound is and how a stereo image is created.
speakers in an array around the listening area, so that the music is always surround- ing you, regardless of the direction you face. The rule of thumb is to add one pair of speakers for every 100 to 200 square feet of listening area.
the wall or even down low at power outlet height, in the ceiling, near corners, or directed at reflective objects and walls. The more reflected sound there is in the room the stronger the ambient effect at low vol- umes.
lation of an array of speakers. If you place them near a hard reflecting surface you can make one pair of speakers sound like sever- al. Create as many reflections as possible by mounting the speakers.
Inst allation Fundamen tals Running the Speaker Wire in New Construction If you have doubts about whether you are capable of installing Niles A T Series speak- ers in your walls, consult a Niles dealer or professional installer . They have special tools, techniques, and experience to make the impossible possible.
Pulling the Cable Pull the cable in sections (from the stereo to the volume control, from the volume control to the speaker). Start with the longest sections and use left over wire to complete the short sections.
stereo system itself (See Figure 9) . The other very common route is through the bottom plate of the wall into an unfinished basement or crawl space. Identify where all of your electrical, phone, and TV wiring is likely to be and plan to route around it all.
Sometimes, an under -the-carpet run is possible (there are special flat speaker wires made for under -the-rug wire runs). As a last resort, heating and air condi- tioning vents can be used as wire race- ways for plenum rated wire (check your local building codes, some municipalities require conduit).
Inst allation of Br acket s, Fr ames and Grilles in Ne w Construc tion Stage One: Before Drywall is Hung Insulating the W all Cavity . If feasible, fill the wall cavity with insula- tion at this point. Attach the wings to the bracket by snapping them into the sides of the bracket.
Screw one side of the assembled bracket with wings to the stud using one of the sup- plied screws. Level the bracket. Screw the other side of the bracket to the stud. T wo or three screws (depending upon the size of the model) on each side makes for a very secure installation.
Inst allation of Br acket s, Fr ames and Grilles in Existing W alls Important: Before you cut into any wall, review the sections on running wire and speaker placement.
7. Attach the frame to the bracket by screw- ing the frame to the bracket using the supplied screws. Do not overtighten the screws, this will distort the frame and the grilles will not fit (this is not permanent, just loosen the screws and the grille will pop in).
Installing the Speaker If the grille is already installed, remove it by using a bent paper clip or the tip of a corkscrew and pulling it away from the frame (See Figure 1 8) . 1. Separate the speaker wire so that at least two inches of each conductor are free.
In-W all at Ear Level The A T8500 and A T8700 speakers will per- form their best when installed at ear level and spaced within the “good placement zone for music” (See “Speaker Placement” on page 5) .
When utilizing A T8500 or A T8700 speakers to reproduce rear channel information in a home theater , the goal is to create as many reflections as possible by mounting the speakers up high in the wall or in the ceiling and aim the Midrange/T weeter Array into the corners or at an adjoining wall to diffuse the sound (See Figures 5 and 6 on page 8) .
