Congratulations! Thank you for choosing a High Definition In-Wall Loudspeaker from Niles. With proper installation and operation, you'll enjoy years of trouble-free use. Niles manufactures the industry's most complete line of custom installation components and accessories for audio/video systems.
thunderous action in a movie. They are perfect anywhere that quality of sound is the most important consideration. The HD or High Definition group of In-Wall Loudspeakers offers speakers expressly designed for superior sonic quality. They employ advanced technology components designed to extract the subtle nuances in recorded music or the An HD5/HD6/HD8/HD8.3 Speaker Kit; and the corresponding Bracket Kit (5, 6 or 8) is required to install one pair of HD5/HD6/HD8/HD8.
Features and Benefits BumpBack™ Woofer Magnet Niles engineers have utilized a unique motor construction enabling far greater “throw” or voice coil excursion. This allows a high level of bass performance to be achieved. Moisture Resistant Construction The HD loudspeakers are suitable for use in high moisture environments. The drivers are impervious to moisture; the grille is made of powder-coated aluminum, and all exposed hardware is made of stainless steel.
Installation Considerations Figure 1 Model HD8 Shown New Construction Wings Bracket Frame Speaker Baffle IR Knockout Grille Installation Considerations Recommended Amplifier Power For satisfactory performance, we recommend an amplifier with a power rating of ten to one hundred watts for the HD5; and ten to one hundred twenty-five watts for the HD6, and ten to one hundred fifty watts for the HD8 and HD8.3. Curiously, most speakers are not damaged by large amplifiers but by small amplifiers.
Installation Considerations er, so you must connect the wire from the amplifier to the volume control and then from the volume control to the speaker. Speaker Wire Use 2-conductor speaker wire when connecting HD speakers to your receiver or amplifier. For most applications, we recommend you use 16 or 18 gauge stranded wire. For wiring runs longer than 80 feet we recommend 14 gauge stranded wire. The no-strip terminals of the HD speakers will accommodate 12 to 18 gauge wire.
Placement for Critical Listening If you like to imagine that the band or orchestra is playing in front of you as you listen to music, or you are very conscious of clarity, detail and the textures of the individual 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.
Speaker Placement The Boundary Effect Corners can affect the bass response of the speaker powerfully! This is called the boundary effect. You will emphasize particular bass frequencies and cancel out other bass frequencies when you place speakers close to the wall/ceiling boundary or a corner wall boundary. This can make the speaker sound excessively boomy and inaccurate to some listeners, while to others it just seems like more bass sound.
A single pair of HD Loudspeakers, properly placed, can create a very convincing simulation of an array of speakers. If you place them near a hard reflecting surface you can make one pair of speakers sound like several. Create as many reflections as possible by mounting the speaker up high in the wall so that the ceiling will act as a powerful reflector.
Installation Fundamentals Installation Fundamentals Running the Speaker Wire in New Construction If you have doubts about whether you are capable of installing a Niles HD loudspeaker in your walls, consult a Niles dealer or professional installer. They have special tools, techniques, and experience to make the impossible possible. The installer can provide you with an estimate before any work is done. Scheduling and Preparation Plan to schedule the speaker wiring after the electrical wiring is finished.
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. If you plan to pull many rooms at the same time through a central route, walk off the distance to each destination, add a generous fudge factor for turns and other obstacles, then cut off each section so that you have a bundle of wires you can pull at once.
Installation Fundamentals cover plate and switch or receptacle, and shining a penlight into the wall. If you have access to an attic or basement space you can quickly see which part of the wall space is free of obstructions (See Figure 5).

In traditional wood stud/drywall construction you can cut the hole for the speaker and utilize the large hole to auger holes across, up or down the wall for as far as your drill bit will take you. If you have matching paint and take reasonable care in patching you can cut a hatch in the drywall at each stud, run your wire, and patch and touch-up the wall (See Figure7). Figure 6 Installation Fundamentals plenum rated wire (check your local building codes, some municipalities require conduit).
Installation of Brackets, Frames and Grilles in New Construction Installation of Brackets, Frames and Grilles in New Construction Stage One: Before Drywall is Hung. Insulating the Wall Cavity. If feasible, fill the wall cavity with insulation at this point. Attach the wings to the bracket by snapping them into the sides of the bracket. The wings can be shortened by breaking them along the scored lines if their length will interfere with a corner or eaves.
Remove the grilles before painting. If you are using spray paint, use two thin coats without any primer. If you are using a compressor and a spray gun, use the finest, most diffuse setting. Practice first on some paper if you have no experience painting with spray paint. If you are using an applicator or brush, and a can of paint, thin the paint first. You do not want to have to poke hundreds of holes in your beautifully painted grilles.
Installation of Brackets, Frames and Grilles in Existing Walls Installation of Brackets, Frames and Grilles in Existing Walls IMPORTANT: Before you cut into any wall, review the sections on running wire and speaker placement. 1. Drill a 1/8” pilot hole just barely through the wallboard or dry wall (1/2” to 5/8” deep in most homes) about an inch below the center of your proposed speaker location (an inch to the side if you are mounting the speaker horizontally).
4. If you are cutting into lath and plaster walls, use masking tape to outline your penciled marks, drill the four corners with a 1/4” bit and use a razor to score the plaster down to the lath beneath. Then use a chisel to remove all of the plaster within the taped outline. Finally, insert a metal cutting blade into a sabre saw and very slowly and carefully saw the lath. Sawing the lath can easily vibrate plaster off the wall.
Installation of the Speaker and Grille in New or Existing Construction 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 13). 8. IMPORTANT: When installing the speakers in the ceiling, or Figure 13 if the installation is in an 1. Separate the speaker wire so earthquake zone, it is recomthat at least two inches of each mended that you utilize the conductor are free.
2. Play some music with the amplifier or radio set to Mono. 3. Listen to the richness of the bass and the loudness of the sound. 4. Turn off the amplifier and reverse the connections on one amplifier channel only. 5. Repeat the listening test with the same setting of the volume control. When the sound has a richer bass and is slightly louder the speakers are working together or “in-phase”. Figure 17 Speaker Phase Speaker wire has two conductors.
Installation of the Speaker and Grille in New or Existing Construction 19 Adjusting the Tweeter The tweeter is housed in a precision adjustment mechanism which enables precise aiming of the directional high frequencies to provide optimum performance. To adjust the tweeter: 1. Carefully grasp the tweeter housing by placing your thumb and forefinger in the indentations provided. 2. Rotate the tweeter housing either clockwise or counter clockwise as required.
