DS00245A/CS 3/8/99 4:13 PM Page 2 Introduction The CS or Contractor Series group of Blueprint Series In-Wall Loudspeakers ® offers speakers expressly designed for flexibility of use. 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.
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.
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.
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.
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.

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.
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.
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.

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.
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).

IMPORTANT: Before you cut into any wall, review the sections on running wire and speaker placement. 1.
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. To prevent damage to the crossover network Installing the Speaker you must remove the If the grille is already knockout from the rear of installed, remove it by the speaker. Do not attempt using a bent paper clip or to remove the knockout the tip of a corkscrew and with the speaker face up.
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.
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.
