They function well as primary speakers in bedrooms, dens or living rooms; as main or surround speakers in home theaters; or in large arrays in commercial spaces. The CS525/CS650 offer a unique combination of adaptability, performance and value which makes them perfect in a wide variety of applications. DS00245A/CS 3/8/99 4:13 PM Page 3 Features and Benefits Features and Benefits Hi-Polymer Woofer The CS525 and CS650 models feature a unique woofer construction process called Hi-Polymer Bonding that combines a waterproof nylon layer with a traditional pulp-based long throw woofer with a treated foam rubber surround. Both models feature custom perforated baskets to keep construction debris from coming in contact with the woofer cone. Polycarbonate Dome Tweeter The 1” polycarbonate tweeter offers surprisingly wide dispersion characteristics for great stereo imaging, remarkable clarity, and moisture resistance. X-Matrix™ Reinforced Baffle The X-Matrix Baffle design uses specially molded ribs constructed of ABS plastic to add rigidity to the baffle assembly. The end result is better clarity and detail. Absolutely Flush to the Wall Appearance The unique mounting system of the CS loudspeakers powerfully clamps the speaker to the bracket, sandwiching the wall material between them. Additionally, the Niles mounting system is carefully optimized to stiffen the surrounding drywall and prevent it from resonating. You hear only the music, not the drywall. Easy Retrofit Installation in your Existing Home Designed for ease of installation, the Niles mounting system makes installations simple and fast. A supplied template assures fast and accurate hole cutting. The bracket slips behind the drywall and the tightening of the screws sandwich the drywall between the bracket and speaker. The grille mounts over the speaker. 3 Eight Ohm Impedance The speakers are designed to be placed in multi-room systems with many pairs of speakers. The eight ohm impedance is a very easy electrical load for most amplifiers. This allows many pairs of CS speakers to be wired to a single amplifier using a Niles speaker selection system. Low Diffraction, Paintable Aluminum Grilles CS speakers utilize rustproof aluminum grilles. The painted aluminum grille has hundreds of precisely sized perforations, creating an acoustically transparent grille. Infrared Sensor Mount The speaker baffle has a locator designed for the Niles MS-1 MicroSensor,™ a miniature infrared sensor. The MS-1 installs discreetly behind the aluminum grille and therefore minimizes wall clutter in your home. When you want to control your equipment, you simply point your remote control at the speaker from up to 15 feet away. DS00245A/CS 3/8/99 4:13 PM Page 4 Figure 1 Frame/ Speaker Baffle Bracket IR Knockout Grille Installation Considerations Recommended Amplifier Power For satisfactory performance, we recommend an amplifier with a power rating of five to fifty watts for the CS525 and CS650. Curiously, most speakers are not damaged by large amplifiers but by small amplifiers. If your system is playing loudly, a small amplifier will run out of power very quickly. When an amplifier runs out of power it creates damaging “clipping” distortion. A large amplifier will play at the same volume without distorting. See the section on operating the speakers for more information about clipping distortion. Incorporating a Local Volume Control In a multi-room system there is one indispensible control for true convenience—a local volume control. It allows you to adjust the volume of the speakers without leaving the room. Plan to wire the system so that each pair of speakers has its own volume control built into the wall (think of a volume control as a dimmer switch for sound). Niles makes a wide range of high performance indoor and outdoor volume controls. They are available in Standard or Decora® style cover plates (just like your DS00245A/CS 3/8/99 4:13 PM Page 5 Installation Considerations light switches and dimmers). Volume controls are connected in line with the speaker, 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 CS speakers to your receiver or amplifier. For most applications, we recommend you use 16 or 18 gauge wire. For wiring runs longer than 80 feet we recommend 14 gauge wire. The spring loaded terminals of the CS speakers will accommodate up to 12 gauge wire directly. Larger sizes can be accommodated via pin connectors. trol all of the functions of your system from the room with the remote pair of speakers. Niles makes a number of IR sensors which install in the wall, in the ceiling, in cabinetry, on tabletops, or even behind the grille of your Niles CS speakers. An IR sensor requires that a 2-conductor shielded wire (West Penn D291 or equivalent) be home run from each sensor location to the main equipment location. This wire is normally run beside the speaker wire at the same time. Typically, the sensor is placed in a location that faces your listening position. Most remote controls will have an effective line of sight range of 18 to 30 feet with any Niles sensor placed TECH TIP Wire size is expressed by its AWG (American Wire Gauge) number. The lower the number, the larger the wire, i.e. twelve AWG is physically larger than fourteen AWG. When you run wire inside walls, special jacketing (CL-2 or CL-3) is required to both protect the wire and for fire prevention. In some areas conduit is required. For a trouble-free installation, low voltage wire such as speaker wire must be run in accordance with the National Electrical Code and any applicable provisions of the local building code. If you are unsure of the correct installation techniques, wire jacket or type of conduit to use, consult a professional audio/video installer, your building contractor, or the local building and inspection department. Incorporating a Remote Control If you are planning to use a stereo system with a hand held IR remote control, consider the advantages of installing a Niles IR Repeater system. You are able to con- 5 in a wall, ceiling, on a cabinet or tabletop However, when you place a Niles MS-1 MicroSensor behind the perforated aluminum grille of a speaker the effective range is reduced to 9 to 15 feet. Insulating the Wall Cavity For best performance from your speakers fill the wall cavity behind the speaker with fiberglass insulation (e.g. R-19 unbatted insulation). Try to keep the same amount of insulation for each speaker, particularly in the same room, for consistent bass response. DS00245A/CS 3/8/99 4:13 PM Page 6 Speaker Placement 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. Here are some guidelines to make the process of placement quick and easy. Make sure the sound will not be blocked or reflected off of furniture or other objects. You should have a direct line of sight with the front of the speaker. To determine the best position, measure the “listening” distance between the ideal listening position (your favorite chair or couch) and the wall in which you plan to install the speakers. Try to place the speakers so that they are equally distant from your listening spot and at least one half of the listening distance apart (this maintains a large pleasant stereo “image”). In home theater applications where there is a center channel you may choose to space the left and right main speakers farther apart for a “bigger than life” sound with Dolby® encoded movies and TV shows. However, for combined music and movie usage stay within the good placement zone for music. For example; if you are ten feet back from the wall, the speakers should be between five and ten feet apart (See Figure 2). Speaker Placement Zone 10’ 5’ Speaker Placement Zone Figure 2 10’ DS00245A/CS 3/8/99 4:13 PM Page 7 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 good rule of thumb is if you always listen to your current pair of speakers with the bass turned up, you’ll enjoy corner placement. If you keep your tone controls at neutral, try to keep the speakers at least one or two feet from the boundaries of the room. Placement for Varying Listening Positions If you want the freedom to sit anywhere in a room facing any direction, and/or find that you prefer the “all around you” sound of some car stereos to a conventional “sound stage” facing you, consider the speaker placement techniques professional installers use in restaurants and bars. They place speakers in an array around the listening area, so that the music is always surrounding 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. Curiously, this is not so that you can play the music louder, but so that you can play it softer! When you have only one pair of speakers in a large room you will notice that when the sound is perfect in one part of the room, it is too loud near the speakers. By placing more than one pair in the room you will avoid these “hot spots” of loud sound and you will create still more sonic ambiance while maintaining clarity and a rich sound everywhere. 7 You can make listener position still less critical by using mono rather than stereo This can be difficult to achieve with normal stereo amplifiers. However, Niles manufactures Systems Integration Amplifiers which enable one room to be wired in stereo while other rooms are wired in mono! Consult your local Niles dealer for more information. In smaller rooms or rooms that are infrequently used, you typically can’t justify the expense of more than two speakers Try to bracket the room with the two speakers. Diagonal placement is a very effective way to stretch the coverage pattern of two speakers. You can also compromise between direct sound (for detai and clarity) and reflected sound (the ambient or “all around you” effect). By trying to place the speakers so that they create as much reflected sound as possible you emphasize the ambient effect They can be up high in 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 volumes. You should use moderation, however, otherwise the compromise becomes too one sided and at high volumes the sound will be blurred and less distinct. Placement for Rear Home Theater Applications In a home theater, the goal is to reproduce the experience of a great movie theater in our homes. The biggest difference between the two is the rear or surround speaker array in a commercial theater Here, it is not uncommon to see twenty or thirty speakers around the audience This huge array of speakers assures that you will feel completely surrounded by the ambient soundtrack of the movie Film makers try to use the “surround” DS00245A/CS 3/8/99 4:13 PM Page 8 soundtrack to envelope you in the environment on screen. They will place background music, rain sounds, traffic noise, etc. on the “surround” soundtrack. In a home with a single pair of speakers it is easy for the jungle sounds to sound like they are “in the middle of your head” just like headphones! A single pair of CS 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. If you place the speakers near a corner, wash the sound down a wall from a ceiling location, or mount the speakers as far away as you can from the listening area, more reflections will occur. However, all of these placement techniques require that you work your surround sound amplifier channels harder. If the surround sound system you are using has a small five or ten watt amplifier for the rear speakers, stay within five to eight feet of the listening location. If you are using a 25 to 50 watt amplifier you can mount the speakers 10 to 15 feet away from the listening location and still achieve reasonably high volume levels. Of course, the best way to emulate the sound of multiple speakers is to use multiple speakers. In large or unusually shaped rooms this might be the only way to achieve a good effect. If you like to listen to music surround modes which emulate concert hall acoustics, more than two surround speakers will prove extraordinarily effective. With Niles CS loudspeakers it is easy to add another pair without affecting the decor of the room. However, you will need to use a much more powerful amplifier than that which is built into a typical surround sound receiver or amplifier. Niles makes a number of Systems Integration Amplifiers with proprietary features that make them uniquely suited to enhance a good surround sound system. Consult your Niles dealer for more information. DS00245A/CS 3/8/99 4:13 PM Page 9 Installation Fundamentals Installation Fundamentals Running the Speaker Wire in New Construction If you have doubts about whether you are capable of installing a Niles Blueprint Series In-Wall Speaker 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. That way you can avoid wire routes which could potentially induce hum over the speaker wire. The basic rules are: • Never run speaker wire through the same hole as an electrical cable. • Never run speaker wire into the same J-box as electrical cable. • Avoid running the speaker wire beside the electrical cable. Keep it at least three or four feet distant from any electrical power cable. Figure 3 Side-by-side wiring is unavoidable in particular spots in every house, just move the speaker wire route away as soon as possible. If construction forces a side by side run for more than ten feet, install meta conduit or shielded speaker wire. Lowvoltage wires such as doorbells, intercoms, telephone, security, or television cannot cause interference or hum on your speaker wires, so you can safely run all of them at the same time, through the same holes, side-by-side. Before you drill any holes, mount the speaker brackets in the desired speaker locations and mount p-rings or open backed J-boxes where the in-wall volume controls and stereo equipment will be. Safety First! Wear gloves, safety goggles and head protection when drilling. Avoid nails, they ruin bits and they can create injury. Pay particular care when using “hole-hogs” and other powerful electric drills; the torque of the drill when suddenly stopped by a nail can break the wrist of a strong man. Drilling Use a bit that is large enough for the wires you plan to run. An auger bit is the preferred bit for rough-in wiring. It will actually pull itself through the wood, so that the drill motor, not you, does most of the work. You will be drilling a lot of holes, so this is important. Always drill the holes in the center of the stud. If you have to notch the stud or dril the hole closer than one inch from the edge of the stud, protect the wire with a nail plate (See Figure 3). When drilling holes in ceiling joists dril in the center of the joists and try to locate the hole near the end of the joist. DO NOT drill through a “gluelam” or any load bearing beam without the direction of your contractor. 9 DS00245A/CS 3/8/99 4:13 PM Page 10 Try to line the holes up perfectly, because it makes pulling the wire much easier. A good technique is to snap a chalk line across the face of the studs or against the bottom of the ceiling joists. Then work backward so that you can always see the holes you have already drilled. Paying careful attention to this will save you a lot of time later on! 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. Whenever you run the wire further than four and one half feet from a hole in a stud or joist (open attic space, going up walls, etc.), fasten the wire to the joists or studs using cable clamps or appropriately sized wire staples. The wire should not have large sags in it, nor should it be too tight. Try to protect the wire from being stepped on in attics or other unfinished crawl spaces. There are guard strips, raceways and conduits which can be used to protect the cable. Consult the local building code for special requirements in your area. Concealing Speaker Wire in Existing Walls This is actually a fairly simple task if you restrict your choice of speaker locations and wire routes to the interior walls or ceilings of your home. Interior walls in almost all North American residences are hollow, so that it is easy to flush mount speakers into them and route new speaker cable around the house. What you see when you look at the painted wall board, plaster, or paneling is only the skin of the wall. Behind the skin is the skeleton; two-by-four wood or metal “studs” running vertically from the floor to the ceiling in walls and two-by-six or larger “joists” running horizontally in the ceilings and floors. In between the studs and the joists is the space for the wiring and plumbing of your home. Exterior walls are different. They must insulate the house from the heat and cold outside, so they are stuffed with insulation. The national building code requires that the hollow wall space in exterior walls be broken by a horizontal stud placed between the vertical studs. This “fire blocking” makes it very difficult to retrofit long lengths of wire. In some areas of the country the exterior walls are constructed of solid masonry, and have no hollow space for speakers or wires. Start by examining all the possible routes you might take to run the speaker wire from the speaker to the volume control and back to the stereo. Use a stud sensor or other device to locate the internal structure of the wall. You want to avoid all studs or joists. A typical route would be: from the speaker location up the inside of the wall to a new hole drilled into the top “plate” (horizontal two-byfour at the top of the inside of the wall), into the attic crawl space, then down to the volume control location through another top plate, back up to the attic, across the attic, and finally down another plate to the wall behind the stereo system itself (See Figure 4). The other very common route is through the bottom plate of the wall into an unfinished basement or crawl space. DS00245A/CS 3/8/99 4:13 PM Page 11 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 the wire is free of obstructions (See Figure 5). Volume Control Location Speaker Location Figure 4 Stereo Location Identify where all of your electrical, phone, and TV wiring is likely to be and plan to route around it all. You can accidentally induce 60 Hz hum on your speakers if you run your speaker wire right beside electrical wire for more than a few feet. Try to keep speaker wire running parallel to power cables at least 3 feet away. To find exactly where an electrical cable is routed, try inspecting the inside of the wall by turning off the breaker for a particular power outlet or switch, removing the Unobstructed space for speaker wiring Figure 5 11 When you don’t have access above or below the wall, try to estimate the existing wire and pipe locations from the positions of electrical outlets and plumbed fixtures on both sides of the wall. Take a look at the outside of your house too, sometimes conduit, vents or drain pipe will be visible that give useful information Choose the route with the fewest potential obstacles. If your house is built on a slab or you are wiring between two finished floors, look for baseboards which could be removed and replaced with the wire behind them Doorjambs can be removed and often have enough space for speaker wire al the way around the door (See Figure 6). 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 conditioning vents can be used as wire raceways for DS00245A/CS 3/8/99 4:13 PM Page 12 plenum rated wire (check your local building codes, some municipalities require conduit). 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 Figure 7). When you are dealing with the unknown because of the structure of your home, or with difficult to patch wall materials like plaster, lath and plaster, faux finishes, wallpaper etc., be patient. A careful study of the potential problems before you start the job will pay off. Figure 7 Figure 6 DS00245A/CS 3/8/99 4:13 PM Page 13 Installation of Speakers Installation of Speakers If the wires movement is obstructed by a pipe or cable, fill the hole (s) with spackle or other patching compound and try another location. 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). BE VERY CAREFUL NOT TO DRILL THROUGH EXISTING WIRES, PIPES, OR STRUCTURE. IF YOU FEEL ANY EXTRA RESISTANCE AS YOU ARE DRILLING, STOP. Cut a piece of coat hanger equal to the width of the bracket. Bend the wire in half creating a right angle. Poke the “Lshaped” wire into the pilot hole and turn it in a complete circle. If it turns freely, repeat the procedure from a hole about an inch above the center of your proposed speaker location (See Figure 11). Figure 11 13 2. When determining the final location of the cutout keep in mind that the frame and bracket will extend beyond the cutout. Make sure that you do not place the edge of the cutout directly next to a stud. Locate the studs using a stud sensor or hand-knocking. Once you have determined the correct position for the cutout, hold the supplied template up to the wal surface. Level the template in either the horizontal or the vertical position and mark the wall with a pencil. Drill the four corners with a 1/4” drill bit. 3. If you are cutting a painted or wal papered drywall use a sheetrock or keyhole saw. Cut the hole with the saw at a 45 degree angle. That way, the drywall section can be replaced cleanly if there is an unseen obstruction behind the wall. BE VERY CAREFUL NOT TO SAW THROUGH EXISTING WIRES, PIPES, OR STRUCTURE IF YOU FEEL ANY EXTRA RESISTANCE AS YOU ARE CUTTING, STOP. 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 meta cutting blade into a sabre saw and very slowly and carefully saw the lath. Sawing the lath can easily vibrate plaster off the wall. If you have the patience, use a pair of tin snips to slowly nip away at the lath instead. There is no risk with this method, it is just time consuming. DS00245A/CS 3/8/99 4:13 PM Page 14 Installing a Niles MS-1 MicroSensor™ There is a 1/2" round molded "IR Sensor Knockout" on the face of the speaker baffle.

Connect all wires and continue 3. If you have gold pin connectors which your installation. you wish to use, affix them to the stripped wire ends now. 5. Fill the wall cavity with insulation at this point. Remember to use equal amounts of insulation for each speaker. 4. Connect one stripped wire end (or connector) to the black and one to the red terminal. Pay attention to the markings on the wire. Each speaker must be connected to the amplifier in the same way. 5. Slip the bracket through the hole. Orient the speaker so that the speaker is level. Secure the speaker and the bracket by tightening the baffle 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). The screws should pull the speaker and bracket together (sandwiching the drywall) so that the frame is absolutely flush with the wall surface. There should be no gaps between the wall and the frame (See Figure 13). 6. Carefully fit the grille into its recess so that it is barely in place. Starting with one corner, go around the speaker, pushing the grille in a little bit each time. You should be gentle, the aluminum grille can be easily bent out of shape. The speaker will have an absolutely flush appearance when it is fully in place. Figure 13 DS00245A/CS 3/8/99 4:13 PM Page 15 Installation of Speakers Speaker Phase Speaker wire has two conductors. One conductor is attached to the negative (-) terminals and one conductor is attached to the positive (+) terminals of both your speaker and your amplifier. Usually, the wire is marked for your convenience. There are different ways wires are marked: a stripe on one wire, a ribbed area of one conductor you can only feel, different colors of metal wire on each conductor, or there might be a fabric strand or string wound into one of the conductors. Of course, there are some wires which appear completely identical. Be careful, or you might make a mistake. If you make a mistake, one speaker will be playing “out-of-phase” with the other speaker. An out-of-phase pair of speakers work against each other and the sound of the two speakers playing together will be lacking in bass and be “phasey” sounding. If you suspect the sound is not right and you cannot see any markings on the wire, try this simple test: 1. Stand half way between the two speakers. 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”. 15 Painting the Aluminum Grilles The grille is important to the sound of the CS loudspeakers. Do not fill the holes of the grille with paint. The grille is constructed of aluminum with a perfectly even powder coat overall. This powder coat is an ideal primer. 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. DS00245A/CS 3/8/99 4:13 PM Page 16 Operation Listening at Higher Volumes It requires more power to achieve a reasonable volume of sound in a large room than it does in a small room. It is possible (even if you are not a teenager) to turn the volume so high that the amplifier runs out of power. This creates “clipping” distortion. Clipping distortion makes treble sound very harsh and unmusical. When you hear harsh sounding treble from any good speaker, turn the volume down immediately! Those harsh sounds are masking some much more powerful ultra-high-frequency sound spikes which will quickly damage any fine loudspeaker. You are much less likely to damage a speaker with a large amplifier because it will be very loud indeed before it produces any clipping distortion. Cleaning You can clean the speaker with a dampened soft cloth or paper towel. If the speaker is mounted high up on a wall or ceiling, use a broom to gently brush it off.
