Grille Removing The Speaker If the grille is already installed remove it by using a bent paper clip or the tip of a corkscrew and pulling it away from the frame Utilizing two small screwdrivers or two needle nose pliers release the snaps that hold the speaker to the frame Insert the screwdrivers into the holes in the snaps and exert force straight down towards the woofer until the snaps release Once the snaps release the speaker can be tilted away from the frame to be removed Do not attempt to use the frame for leverage as this may damage the surface of the frame See Figure 21 Figure 21 Operation Listening at Higher Volumes lt 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

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 infre quently 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 pat tern of two speakers You can also com promise between direct sound for detail 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 possi ble 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 vol umes You should use moderation how ever otherwise the compromise becomes too one sided and at high volumes the sound will be blurred and less distinct Placement for Home Theater Rear Applications In a home theater the goal is to repro duce the experience of a great movie the ater 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

10. 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 two or three 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 conven tional sound stage facing you consider the speaker placement techniques profes sional installers use in restaurants and bars They place speakers in an array around the listening area so that the music is always surrounding you regard less 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 plac ing more than one pair in the room you will avoid these hot spots of loud sound and you will create more sonic ambiance while maintaining clarity and a rich sound everywhere You can make listener position still less critical by using mono rather than stereo This can be difficult to achieve with nor mal stereo amplifiers However
