Operation

Listening at Higher Volumes

It requires more power to achieve a reason- able 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 immedi- ately! Those harsh sounds are masking some much more powerful ultra-high-fre- quency 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 clip- ping distortion.

Cleaning

You can clean the speaker with a damp- ened 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.

Speaker Placement

Introduction

Although the CM5PR and CM6PR have extensive ability to compensate for unusu- al placements with their unique pivoting tweeters and acoustic fine-tuning switch- es; placement is still the primary tool for satisfying your particular listening needs. In the following section, we discuss how speakers should be placed and how tweet- ers should be directed and how the acoustic fine-tuning switches should be set for different purposes.

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, or you listen criti- cally to movie soundtracks or music videos in your home theater, you will need your speakers placed so that they are optimized for critical listening. 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 lis- tening position (your favorite chair or couch) and the location 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 far- ther 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 place- ment zone for music. For example; if you are ten feet back from the speakers, the speakers should be between five and ten feet apart (See Figure 4).

Tweeters should be directed at the listen- ing position.

CM6PR, CM5PR specifications

Niles Audio, a renowned name in the audio industry, introduces the CM5PR and CM6PR, both part of their premium in-ceiling speaker range designed to deliver exceptional sound quality in any environment. These models are engineered for customers who prioritize both aesthetic appeal and superior acoustics in their home audio systems.

The CM5PR features a 5.25-inch polypropylene woofer, delivering a well-balanced sound profile that is rich in detail across the entire audio spectrum. Coupled with a 1-inch aluminum dome tweeter, it provides crisp highs and smooth midrange tones, making it an ideal choice for music enthusiasts and movie lovers alike. The CM6PR, on the other hand, ups the ante with a larger 6.5-inch polypropylene woofer, enabling it to deliver even deeper bass response. The tweeter remains consistent, ensuring both speakers provide uniform sound quality throughout different rooms.

One of the standout technologies behind the CM5PR and CM6PR is the patented IN-CEILING speaker design, which minimizes sound distortion while providing a broad dispersion pattern. This enables a more immersive listening experience, as the speakers can fill the room with clear sound regardless of the listener's position. The speakers are also equipped with a unique speaker grille that can be painted to match the room decor, making them blend seamlessly into any environment.

Furthermore, both models come with adjustable tweeter and woofer controls that allow users to customize the sound to their liking. This is particularly beneficial for rooms with challenging acoustics, where fine-tuning can lead to significantly improved audio performance.

Installation is simplified by their direct-connect system that allows for quick integration into existing audio systems. The CM5PR and CM6PR speakers are compatible with a wide range of amplifiers and receivers, making them versatile choices for various setups.

In terms of durability, Niles Audio has designed these speakers with a moisture-resistant construction, making them suitable for installation in humid areas such as kitchens and bathrooms without compromising sound quality.

In summary, the Niles Audio CM5PR and CM6PR speakers are exceptional choices for anyone looking to enhance their home audio experience while ensuring aesthetic harmony with their living spaces. With their advanced technologies and thoughtful design features, they set a standard in in-ceiling audio solutions.
