INSTALLATION CONSIDERATIONS

We recommend using the following tools and material to install your Niles CM loudspeaker:

•Cordless drill with 1/4 – and 1/2- inch drill bits and a 1-inch paddle drill bit (for drilling through studs)

•Stiff wire, fish tape or glow rods for routing cables

•Rubber gloves and protective eyewear

•Keyhole or drywall saw

•Phillips screwdriver set

•Wire stripper

•Stud finder

•Cable ties

•Pencil

Before starting the installation, please observe the following precautions:

•Turn off all system power before making any connections

•Always wear protective eyewear when using tools

•Make sure hands are clean before installation

•Wear gloves when working with fiberglass insulation

RUNNING WIRES IN WALLS OR CEILINGS

When running loudspeaker wire inside walls or ceilings, use special jacketed cable (a minimum of 18 to 16-gauge two-conductor CL-2 or CL-3 rated loudspeaker wire) to protect the wire and for fire prevention. In some areas, conduit is also required. For a trouble-free installation, low-voltage wire such as loudspeaker 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, building contractor, or the local building and inspection department.

SELECTING THE LOCATION FOR YOUR LOUDSPEAKERS

The CM850Si loudspeaker is designed to be installed in any standard ceiling. There are two considerations for placing the loudspeaker; ease of running the cable to the loudspeaker and coverage of the loudspeaker. The best stereo effect will be achieved if the loudspeaker is placed in the center of the listening area. Avoid installing the loudspeaker near a corner to prevent a “boomy” or diffracted sound. The CM850Si loudspeaker will cover an area of a circle with a 16-foot diameter when mounted at an 8-foot height and pointed straight down. (See Figure 1)

EXISTING CONSTRUCTION INSTALLATION

IMPORTANT: BEFORE YOU CUT INTO ANY WALL, REVIEW THE PRIOR SECTION ON LOUDSPEAKER PLACEMENT WHEN SELECTING THE LOCATION FOR YOUR LOUDSPEAKERS.

1.When determining the location of the loudspeaker cutout, keep in mind that the mounting dogs will extend 3/4” beyond the cutout. Make sure that you do not place the edge of the cutout directly next to a ceiling joist. Locate the joists using a stud sensor or by hand knocking. Use the supplied cutout template (remove the largest perforated circle and use cardboard square with hole as the template) to determine how large of a hole you will need to cut. These templates are packed with your loudspeakers between the styrofoam packing and the ends of the box.

2.Once you have determined a possible position for the cutout, drill a 1/8” pilot hole just barely through the ceiling (1/2” to 5/8” deep in most homes) in the center of your proposed loudspeaker location.

BE VERY CAREFUL NOT TO DRILL THROUGH EXISTING WIRES, PIPES, OR STRUCTURE. IF YOU FEEL ANY EXTRA RESISTANCE AS YOU ARE DRILLING, STOP.

CM850Si specifications

The Niles Audio CM850Si is a robust in-ceiling speaker that combines high-performance sound quality with the aesthetic appeal required for modern home environments. Designed with the consumer in mind, this model stands out in the audio market due to its innovative features and reliable build quality.

One of the most notable features of the CM850Si is its 8-inch polypropylene woofer, which delivers rich, deep bass responses while maintaining clarity across all frequencies. This driver is paired with a 1-inch pivoting silk dome tweeter, allowing users to direct sound towards the listening area, enhancing the overall audio experience. The combination of these elements makes the CM850Si suitable for various applications, from filling a room with music to enhancing home theater experiences.

The CM850Si is engineered with Niles' exclusive SmartSelect™ technology, which optimizes the speaker's frequency response based on its installation environment. This unique feature allows the speaker to adapt to different room acoustics, ensuring that sound reproduction remains consistent, regardless of where the speaker is mounted. This adaptability makes installation simpler and less time-consuming, as installers can achieve excellent sound without extensive calibrations.

Another key characteristic is its elegant design. The CM850Si features a low-profile bezel and a paintable grille, allowing it to blend seamlessly into any ceiling, whether it's in a living room, kitchen, or dedicated home theater space. The speaker's traditional round shape can also be mounted in square configurations, thanks to available optional square grilles, further enhancing its versatility in design.

Durability is not overlooked in the CM850Si. The construction includes moisture-resistant materials, making it suitable for installation in bathrooms or covered outdoor areas without compromising sound quality. With a power handling capacity of up to 150 watts, this speaker is well-equipped to handle a variety of usage scenarios, from soft background music to dynamic movie audio.

In summary, the Niles Audio CM850Si in-ceiling speaker offers a compelling combination of advanced audio technology, sleek design, and reliable performance. The incorporation of SmartSelect™ technology, high-quality drivers, and installation adaptability make it an excellent choice for consumers seeking an unobtrusive yet powerful audio solution in their homes. Whether used for music listening or home theater applications, the CM850Si delivers excellence in sound that meets the demands of today's audio enthusiasts.
