They employ advanced technology components designed to extract the subtle nuances in recorded music or the thunderous action in a movie. They are Introduction Features and Benefits perfect anywhere that quality of sound is the most important consideration. Each model features Niles' patented two-piece no-strip speaker wire terminal which reduces installation time. Features and Benefits Injection Molded TCC Woofer with Butyl Rubber Surround The CM High Definition series loudspeakers employ a newly developed cone material that combines injection molded polypropylene with talc, carbon and ceramic stiffening agents. The result is a cone that offers extreme stiffness and light weight for accurate, dynamic response. Additionally, the woofer employs a vented pole piece for increased bass linearity and a Butyl Rubber Surround for improved midrange damping and clarity as well as moisture resistance. Pivoting Fluid-Cooled Ultra-Wide Dispersion Tweeter in Custom Pivoting Coaxial Enclosure The CM High Definition series Teteron Tweeter employs a tri-laminate design consisting of an inner textile layer which forms the dome, a high damping layer to kill unwanted resonances and an outside layer of urethane to add stiffness and prevent breakup modes. The result is a transparently clear, sweet, natural sounding tweeter which still maintains extended frequency response. The tweeter can pivot up to 20° within its mount allowing for perfect alignment of the high frequencies, optimum performance and without the diffraction distortion typical of traditional pivoting tweeters. No-Strip Speaker Terminal Niles patented No-Strip terminal enables speakers to be connected without stripping the speaker wire. No-Strip terminals eliminate fumbling with wire strippers and input terminals. They are color coded and simply plug into the crossover circuit boards on the back of Niles speakers, resulting in positive in-phase connections every time. Moisture, UV Resistant Construction The CM5HD, CM6HD and CM8HD loudspeakers are suitable for use in high moisture environments. The drivers are resistant to moisture and UV exposure; the grille is made of powder-coated aluminum. However, the speakers are not waterproof and direct contact with water should be avoided. Engineered for Ceiling Placement The CM5HD, CM6HD and CM8HD have been specifically designed and tuned for optimum performance when mounted in a ceiling. The custom designed low diffraction tweeter housing is mounted coaxially to avoid the "venetian blind" effect common with ceiling speakers that employ sub-baffles as tweeter mounts. The 20° tweeter pivot angle ensures optimum high-frequency coverage. contined on next page 2 Installer Selectable Acoustic Fine Tuning Installers can select to de-emphasize the bass or treble by 2dB to accommodate reflective surfaces and corner loading. This selection is accomplished via bafflemounted controls that are accessible after the speaker has been installed. MicroPerfTM Grilles The CM5HD, CM6HD and CM8HD employ Niles exclusive MicroPerfTM grille construction. the exceptionally tight hole pattern provides acoustic transparency at all audio frequencies and enables the speaker elements to remain invisible. MicroPerf grilles can also be painted to blend seemlessly with the surrounding decor. Easy Installation The CM5HD, CM6HD and CM8HD employ a bracketless mounting system in existing ceilings. Simply cut a hole in the mounting surface, remove the grille from the speaker, connect the wires and place the speaker in the hole. Then tighten the four mounting "dogs" via the front panel screws. The dogs first swivel 90°, then clamp the speaker frame to the drywall as you tighten the screws. 4 or 8 ohm Selectable Impedance The dual voice coil feature of the CM5HD, CM6HD and CM8HD gives the installer flexibility to select the speaker's impedance -- 4 ohms for systems where maximum current transfer and output level is desired; 8 ohms for systems utilizing multiple speaker pairs where amplifier loading is a consideration. Hole Saving Bracket Available as an optional accessory, CM5 Series, CM6 Series and CM8 Series New Construction Brackets can be installed as a "hole-saver" before the drywall goes up. The drywall contractor cuts the holes as the drywall is installed, reducing installation time and minimizing the chance for lost wires.

Connectors accommodate 12 to 20 gauge stranded wire. Installation Considerations Recommended Amplifier Power For satisfactory performance, we recommend an amplifier with a power rating of 10 to 100 watts for the CM5HD; 10 to 125 watts for the CM6HD and 10 to 150 watts for the CM8HD. 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.
